Keeping track of File System Utilization in Ops Center 12c

Enterprise Manager Ops Center 12c provides significant monitoring capabilities, combined with very flexible incident management. These capabilities even extend to monitoring the file systems associated with Solaris or Linux assets. Depending on your needs you can monitor and manage incidents, or you can fine tune alert monitoring rules to specific file systems.

This article will show you how to use Ops Center 12c to

  • Track file system utilization
  • Adjust file system monitoring rules
  • Disable file system rules
  • Create custom monitoring rules

A recording of this community call is now available here:

Monitoring File Systems for OS Assets

The Libraries tab provides basic, device-level information about the storage associated with an OS instance. This tab shows you the local file system associated with the instance and any shared storage libraries mounted by Ops Center.

More detailed information about file system storage is available under the Analytics tab under the sub-tab named Charts. Here, you can select and display the individual mount points of an OS, and export the utilization data if desired:


In this example, the OS instance has a basic root file partition and several NFS directories. Each file system mount point can be independently chosen for display in the Ops Center chart.

File Systems and Incident  Reporting

Every asset managed by Ops Center has a "monitoring policy", which determines what represents a reportable issue with the asset. The policy is made up of a bunch of monitoring rules, where each rule describes

  • An attribute to monitor
  • The conditions which represent an issue
  • The level or levels of severity for the issue

When the conditions are met, Ops Center sends a notification and creates an incident.

By default, OS instances have three monitoring rules associated with file systems:

  • File System Reachability: Triggers an incident if a file system is not reachable
  • NAS Library Status: Triggers an incident for a value of "WARNING" or "DEGRADED" for a NAS-based file system
  • File System Used Space Percentage: Triggers an incident when file system utilization grows beyond defined thresholds

You can view these rules in the Monitoring tab for an OS:

Of course, the default monitoring rules is that they apply to every file system associated with an OS instance. As a result, any issue with NAS accessibility or disk utilization will trigger an incident. This can cause incidents for file systems to be reported multiple times if the same shared storage is used by many assets, as shown in this screen shot:


Depending on the level of control you'd like, there are a number of ways to fine tune incident reporting.

Note that any changes to an asset's monitoring policy will detach it from the default, creating a new monitoring policy for the asset. If you'd like, you can extract a monitoring policy from an asset, which allows you to save it and apply the customized monitoring profile to other OS assets.


Solution #1: Modify the Reporting Thresholds

In some cases, you may want to modify the basic conditions for incident reporting in your file system. The changes you make to a default monitoring rule will apply to all of the file systems associated with your operating system. Selecting the File Systems Used Space Percentage entry and clicking the "Edit Alert Monitoring Rule Parameters" button opens a pop-up dialog which allows you to modify the rule.

The first screen lets you decide when you will check for file system usage, and how long you will wait before opening an incident in Ops Center. By default, Ops Center monitors continuously and reports disk utilization issues which exist for more than 15 minutes.

The second screen lets you define actual threshold values. By default, Ops Center opens a Warning level incident is utilization rises above 80%, and a Critical level incident for utilization above 95%

Solution #2: Disable Incident Reporting for File System

If you'd rather not report file system incidents, you can disable the monitoring rules altogether. In this case, you can select the monitoring rules and click the "Disable Alert Monitoring Rule(s)" button to open the pop-up confirmation dialog.

Like the first solution, this option affects all file system monitoring. It allows you to completely disable incident reporting for NAS library status or file system space consumption.

Solution #3: Create New Monitoring Rules for Specific File Systems

If you'd like to have the greatest flexibility when monitoring file systems, you can create entirely new rules. Clicking the "Add Alert Monitoring Rule" (the icon with the green plus sign) opens a wizard which allows you to define a new rule.

 This rule will be based on a threshold, and will be used to monitor operating system assets. We'd like to add a rule to track disk utilization for a specific file system - the /nfs-guest directory. To do this, we specify the following attribute

FileSystemUsages.name=/nfs-guest.usedSpacePercentage

The value of name in the attribute allows us to define a specific NFS shared directory or file system... in the case of this OS, we could have chosen any of the values shown in the File Systems Utilization chart at the beginning of this article.

usedSpacePercentage lets us define a threshold based on the percentage of total disk space used. There are a number of other values that we could use for threshold-based monitoring of FileSystemUsages, including

  • freeSpace
  • freeSpacePercentage
  • totalSpace
  • usedSpace
  • usedSpacePercentage

The final sections of the screen allow us to determine when to monitor for disk usage, and how long to wait after utilization reaches a threshold before creating an incident. The next screen lets us define the threshold values and severity levels for the monitoring rule:

If historical data is available, Ops Center will display it in the screen. Clicking the Apply button will create the new monitoring rule and active it in your monitoring policy.


If you combine this with one of the previous solutions, you can precisely define which file systems will generate incidents and notifications. For example, this monitoring policy has the default "File System Used Space Percentage" rule disabled, but the new rule reports ONLY on utilization for the /nfs-guest directory.

Upgrading Agent Controllers in Oracle Enterprise Manager Ops Center 12c

Oracle Enterprise Manager Ops Center 12c recently released an upgrade for Solaris Agent Controllers. In this week's blog post, we'll show you how to upgrade agent controllers.

Detailed instructions about upgrading Agent Controllers are available in the product documentation here. This blog post uses an Enterprise Controller which is configured for connected mode operation. If you'd like to apply the agent update in a disconnected installation, additional instructions are available here.

Step 1: Download Agent Controller Updates

With a connected mode Ops Center installation, you can check for product updates at any time by selecting the Enterprise Controller from the left-hand Administration navigation tab.

Select the right-hand Action link “Ops Center Downloads” to open a pop-up dialog displaying any new product updates. In this example, the Enterprise Controller has already been upgraded to the latest version (Update 1, also shown as build version 2076) so only the Agent Controller updates will appear.

There are three updates available: one for Solaris 10 X86, one for Solaris 8-10 SPARC, and one for all versions of Solaris 11. Note that the last update in the screen shot is the Solaris 11 update; for details on any of the downloads, place your mouse over the information icon under the details column for a pop-up text region.

Select the software to download and click the Next button to display the Ops Center license agreement.

Review and click the check box to accept the license agreement, then click the Next button to begin downloading the software.


The status screen shows the current download status. If desired, you can perform the downloads as a background job. Simply click the check box, then click the next button to proceed to the summary screen.


The summary screen shows the updates to be downloaded as well as the current status. Clicking the Finish button will close the dialog and return to the Browser UI. The download job will continue to run in Ops Center and progress can still be viewed from the jobs menu at the bottom of the browser window.

Step 2: Check the Version of Existing Agent Controllers

After the download job completes, you can check the availability of agent updates as well as the current versions of your Agent Controllers from the left-hand Assets navigation tab.

Select “Operating Systems” from the pull-down tab lets to display only OS assets. Next, select “Solaris” in the left-hand tab to display the Solaris assets. Finally, select the Summary tab in the center display panel to show which versions of agent controllers are installed in your data center.


Notice that a few of the OS assets are not displayed in the Agent Controllers tab. Ops Center will not display OS instances which do not have an Agent Controller installation. This includes Enterprise Controllers and Proxy Controllers (unless the agent has been activated on the OS instance) and and OS instances using agentless management.

For Agent Controllers which support an update, the version of agent software (in this example, 2083) appears to the right of the currently installed version.

Step 3: Upgrade Your Agent Controllers

If desired, you can upgrade agent controllers from the previous screen by selecting the desired systems and clicking the upgrade button. Alternatively, you can click the link “Upgrade All Agent Controllers” in the right-hand Actions menu:

In either case, a pop-up dialog lets you start the upgrade process. The first screen in the dialog lets you choose the upgrade method:

Ops Center provides three ways to upgrade agent controllers:

  • Automatic Upgrade: If Agent Controllers are running on all assets, Ops Center can automatically upgrade the software to the latest version without requiring any login credentials to the system
  • SSH using a single set of credentials: If all assets use the same login credentials, you can apply a single set to all assets for the upgrade process. The log-in credentials are the same ones used for asset discovery and management, which are stored in the Plan Management navigation tab under Credentials.
  • SSH using individual credentials: If assets use different login credentials, you can select a different set for each asset.

After selecting the upgrade method, click the Next button to proceed to the summary screen. Click the Finish button to close the pop-up dialog and start the upgrade job for the agent controllers.

The upgrade job runs a series of tasks in parallel, and will upgrade all agents which have been selected. Once the job completes, the OS instances in your data center will be upgraded and running the latest version of Agent Controller software.

My Favourite Features of Enterprise Manager Cloud Control 12c - Today’s topic: Incident Management

Enterprise Manager Cloud Control 12c (EM12c) is a huge release, both in terms of its adoption rate (that is, its uptake in the market) and the amount of functionality included in the product. For those of us that have been around for a long time, it’s very reminiscent of the massive functionality leap from Oracle RDBMS version 6 to version 7 – a quantum leap that makes it difficult to even grasp the breadth of the product now.

To try and make the new features a bit more understandable, I’ll be writing a number of blog entries over the coming months to highlight just some of my favourite new features for EM12c. From an administrator’s perspective, one of those standout features (and the subject of today’s entry) has to be incident management.

The goal of incident management is to enable administrators to monitor and resolve service disruptions that may be occurring in their data centre as quickly and efficiently as possible. Instead of managing the numerous discrete individual events that may be raised as the result of any of these service disruptions, we want to manage a smaller number of more meaningful incidents, and to manage them based on business priority across the lifecycle of those incidents.

To do this, Enterprise Manager now provides a centralized incident console called Incident Manager that will enable the administrator to track, diagnose, and resolve incidents, as well as providing features to help rectify the root causes of recurrent incidents. Incident Manager also directly leverages Oracle’s own expertise via My Oracle Support knowledge base articles and documentation to enable administrators to accelerate the process of diagnosing and resolving incidents and problems. Finally, Incident Manager also offers the ability to do lifecycle operations for incidents, so you can assign ownership of an incident to a specific user, acknowledge an incident, set priority for an incident, track an incident’s status, escalate an incident or suppress it so you can defer it to a later time. You can also raise notifications on an incident or open a helpdesk ticket via the helpdesk connectors.

Events

Enterprise Manager continues to be the primary tool for managing and monitoring the Oracle data center, so it manages and monitors Oracle applications as well as the application stack from presentation layer to middleware, databases to hosts and the operating system, as well as non-Oracle technology. When Enterprise Manager detects issues in any of this infrastructure, it raises events. Sample events might be:

1. Metric alerts (for example, CPU utilization or tablespace usage alerts) where a critical threshold you set has been crossed

2. Job events – events are raised by the job system for job statuses that you specify, for example an event is raised to signal the failure of a job.

3. Standards violations – if you are using compliance standards and any of the targets that are being monitored violate any of the compliance standards, then a standards violation event could be raised.

4. Availability events – if a target is down and Enterprise Manager detects that, an availability event that the target is down can be raised

5. Other events – there are other types of events that occur as well

All these events signal particular issues have occurred in the managed data centre. As an administrator, you really want to be able to determine which of these events are significant. From these significant events, you then want to be able to correlate discrete events that are related to the same underlying issue, so you in fact have to manage a smaller number of significant incidents.

Incidents

An incident could then be defined as an object containing a significant event (such as a target being down, for example) or it could be a combination of events that all relate to the same issue (for example, running out of space could be detected by Enterprise Manager as separate events raised from the database, host and storage target types). For example, you may have a performance incident that amalgamates a number of performance events, another incident related to space, and a different incident based on availability problems.

Sound good? OK, so how do we do this? Well, events are significant occurrences in your IT infrastructure and that Enterprise Manager detects and raises. Each event has a set of attributes– what type of event it is, the severity (fatal, critical and so on), the object or entity on which the event is raised (typically a target but it can also be a job or some other object), the message associated with the event, the timestamp at which it occurred, as well as the functional category (such as availability, security etc.)

Some examples of the different types of events include:

· Target availability: raised when a target is down or has gone into an agent unreachable state.

· Metric alert: raised when a metric crosses its threshold.

· Job status change: raised, for example, when a job fails.

· Compliance standard rule: raised when a compliance standard rule is violated.

· Metric evaluation: raised when there is an error with the evaluation of a metric.

· Other events such as SLA Alert, High Availability and Compliance Standard Score violation can also be raised, and of course, users can cause an event to be raised.

Associated with these event types are event severities. The first of these, “Fatal”, is a new severity level in Enterprise Manager specifically associated with the target availability event type for when the target is down. Critical and warning events have the same meaning as they had in previous releases, and then we have the Advisory level. Typically, this is associated with non-service-impacting events such as compliance standard violation events. The informational level is an event severity used to indicate simply that an event has occurred, but there is no need to do anything about it.

As we discussed previously, an actual incident will contain one or more events. Let’s look at the details of an incident with one event. For example, Figure 1 shows us an availability event:

Figure 1: Incident with one event

The event signals that the database DB1 is down and includes a timestamp of when the event was raised. Because this is a target availability event and the database is down, the severity is marked as Fatal. An incident can be created for that event, so the incident contains only one event. In order to manage and track the resolution of the incident, the incident has other attributes such as owner (the Enterprise Manager user that is working on the incident), status, incident severity (which is based on the event severity), priority and a comment field.

Many incidents will instead contain multiple events, where those events are related and pointed to the same underlying cause. In the example shown in Figure 2, we have two metric alert events on a host target -- a memory utilization metric alert event and a CPU utilization metric alert event because the host is starting to suffer from heavy load. We have a warning severity memory utilization metric alert event, and a short time later a critical severity CPU utilization metric alert event.


Figure 2: Incident with multiple events

An incident can be created containing both events in order to manage and track the resolution of the incident. In the current release, the administrator needs to manually combine events into an incident in the Enterprise Manager console (the automatic grouping of related events into an incident is a future enhancement). Again, we have additional attributes associated with the incident like we had in the previous example. Enterprise Manager automatically assigns the incident severity, based on the worst case event severity of all the events contained in the incident. Since the worst event severity is Critical, the incident severity is also set to Critical. Finally, the incident has a summary which is a short description of what the incident is about. The individual events are indicating the machine load is high so you can set the summary to that. Alternatively, you can set the incident summary to be the same as the event messages.

If you are using one of the helpdesk connectors to interface to a helpdesk system, an incident might also result in a helpdesk ticket which can allow the helpdesk analyst to work on the ticket. Within Enterprise Manager, we’ll be able to track both the ticket number and the status of that particular ticket.

Problems

A problem is the underlying root cause of an incident. In Enterprise Manager terms, a problem is specifically related to either an Automatic Diagnostic Repository (ADR) incident or Oracle software incident. Enterprise Manager will automatically create a problem whenever it detects an ADR incident has been raised. An ADR incident can be thought of as a critical Oracle software problem where the resolution of the software problem typically involves contacting Oracle Support, opening a service request and possibly receiving a patch for that problem.

Whenever an ADR incident is raised, we generate one incident in Enterprise Manager for that ADR incident, and we also automatically generate a problem as well. All the ADR incidents that have the same problem signature (that is, the same root cause) will be linked into a single problem object. The administrator can manage the problem in Incident Manager in the same way as you would manage an incident, so you can assign an owner to the problem, track the resolution and so on. In addition, there are in-context links to Support Workbench functionality which allows the administrator to package the diagnostic material, open a service request and view the status of diagnostic activity such as the SR number and ultimately bug number (if one is generated) within the user interface.

Figure 3 shows a diagrammatic example of how incidents and problems are related. Two ADR incidents have occurred, in this example two ORA-600 errors have occurred in my database. Both of these incidents are of critical severity. Enterprise Manager automatically creates a problem containing those incidents. Within the Incident Manager interface you can link to the Support Workbench to open a service request which you can then track from Incident Manager.

Figure 3: Incidents and problems

So now you have an understanding of the terminology and relationships between these terms, what’s next? Well, the next thing to understand is just how you deal with these incidents. That will be the topic of my next blog, so stay tuned for more!

Forrester Consulting: Oracle Real Application Testing Delivers 224% ROI

Leading analyst firm, Forrester Consulting has recently published a Total Economic Impact™ (TEI) Study for Oracle Real Application Testing, an Oracle Database 11g Enterprise Edition option. In the study Forrester Consulting found that Oracle Real Application Testing delivered a very favorable 224% return on investment (ROI), based on a three year risk-adjusted period with a payback of 5.9 months.

Forrester Consulting's TEI results were calculated from in-depth interviews with Oracle customers and applied to a hypothetical organization developed within their TEI financial model. The study measured both the benefits and cost savings in areas around planned and unplanned maintenance, infrastructure upgrades and database performance management.

New Feature Roundup for Oracle Enterprise Manager Ops Center 12c

On April 4th, we announced the release of Oracle Enterprise Manager Ops Center 12c at Oracle OpenWorld in Tokyo. We followed up with a Webcast last week to demonstrate our great new cloud control capabilities.

In today's post, I'm going to discuss the new product features in this version of Ops Center. There are so many that it's a little challenging to cover them all, so I'll start with a high-level summary. In future posts, we'll talk about these features in greater detail, and show how you can use them to manage your datacenter more effectively than ever before!

The Big 3: Cloud Control, Engineered Systems, and Solaris 11

The big news during the product launch was the newly introduced support for Cloud Control, Oracle Engineered Systems and the Solaris 11 operating environment.

Cloud Support and the Virtual Datacenter

Ops Center allows users to build the managed assets into Virtual Data Centers, or vDCs. vDCs can leverage the full power of Oracle technologies, including:

  • Hardware – Sun Oracle servers and Oracle Engineered Systems
  • OS – Solaris 11, Solaris 10 and Oracle Enterprise Linux
  • Virtualization – Oracle VM Server for X86 and Oracle Solaris Zones

The vDC provides a full stack of coordinated resources for Cloud computing, including systems, network infrastructure, storage, virtualization hosts and a self-contained user and permission model. Ops Center users can leverage this functionality in two ways: by logging directly into the Ops Center UI, or by using the programmatic API and CLI for Infrastructure as a Service. (IaaS) These features enable Ops Center to greatly speed the deployment and management process for cloud-based infrastructure.

Oracle Engineered System Support

Ops Center provides management support for the SPARC SuperCluster T4-4, and enhances the existing management capabilities for the Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud.

The SuperCluster and Exalogic systems are delivered with an Ops Center instance that simplifies Oracle Engineered Systems management and allows these systems to be more effectively used as virtual datacenters.

Solaris 11 Management

Oracle Enterprise Manager Ops Center 12c can now be installed on Solaris 11, providing full lifecycle management capabilities for Solaris 11 OS assets. This includes

  • OS provisioning, using the Automated Installer
  • OS update management, using the Image Packaging System
  • Creation and management of Solaris 11 zones and boot environments
  • Solaris 11 OS monitoring analytics

Ops Center allows administrators to effectively leverage the power of Solaris 11, and to use its considerable capabilities for cloud infrastructure.

These features represent a huge advance in Ops Center management. However, Oracle Enterprise Manager Ops Center 12c provides an even greater set of enhancements which touch on all parts of the product functionality. In the sections that follow, I'll present key features for the Ops Center infrastructure, the User Interface, Core Product Functions, Hardware Management and Provisioning, OS Management and Virtualization Management.

Ops Center Infrastructure

Oracle Database

We're now using the Oracle Database 11g for persistence management. Users can install a co-located database with their enterprise controller, or create an instance in an existing DBMS. We've created views in Oracle, providing better data query and reporting capabilities than ever before.

High Availability (HA)

Using Oracle Clusterware, Ops Center can configure two enterprise controller instances in an active-passive HA configuration. What's more, it's now possible to migrate your managed assets between proxy controllers in an Ops Center installation.

Role-Based Permissions Model

Every user is now associated with one or more roles, with each role defining a standard set of capabilities. Ops Center administrators can replicate the roles between users, allowing them to easily assign duplicate management capabilities.

LDAP Directory Servers

It's also possible to import a set of user accounts from an LDAP server, allowing you to easily set up a group of Ops Center users.

User Interface Enhancements

Customizable User Experience

It's now possible to save your Ops Center UI preferences, such as start page, timeout and navigation display.

Configuration Settings

You can now view and edit the Ops Center configuration defaults directly from the UI. This allows you to more easily modify Ops Center defaults such as job timeouts and throttling settings.

Free-Format Tags

All assets can now be associated with user-defined tags, which can be used for searching and filtering. This makes it MUCH easier to keep track of a large number of managed assets.

Core Product Functions

Enhanced Discovery Management

Ops Center allows users to save and customize standard discovery profiles, IP address ranges, and authentication credentials. In addition, Ops Center automatically manages newly discovered assets.

Automated Service Request (ASR) Integration

Ops Center can now forward ASR events for your warrantied hardware assets. With support enabled, incidents with your ASR-compatible assets will be forwarded to Oracle and used to open a service request. You can even provide contact information on a global or per-asset basis.

Integrated OCDoctor

There's now a UI option to run OCDoctor checks, diagnostics and optimizations for the enterprise controller, proxy controller and agent controllers. Diagnostic results are saved, and can be used as the basis for future evaluation and tuning.

Hardware Management and Provisioning

Newly Supported Hardware

Ops Center has always provided rich management capabilities for a broad range of Sun hardware, and this release expands support to the next generation of servers. Key products now supported for discovery and management include

  • The Sun Fire X86 M3 server family
  • The Sun Netra M3 server family
  • The Sun SPARC T4 server family
  • Power Distribution Units (PDUs)
  • The Cisco Catalyst 4948 Switch

ILOM 3.0 Snapshot of BIOS Configuration

Using Oracle's HMP 2.2, Ops Center can save snapshots of the BIOS state for supported ILOM 3 servers. They can subsequently apply the snapshots to easily change SP configuration settings and replicate the state of BIOS to other servers in the datacenter.

WAN Boot Capabilities

Ops Center now supports WAN boot as a provisioning technology for Solaris 10 and 11 for qualified SPARC systems. If systems are compatible, Ops Center automatically uses WAN boot to provision them.

OS Management Capabilities

Agentless OS Management

Ops Center now allows basic OS monitoring and management to be performed without agent installation. In an agentless model, the Proxy controller periodically logs into the managed OS instance and directly performs management actions.

OS Analytics

Ops Center now provides extremely detailed data about OS assets. Administrators can take advantage of service and process-level data, as well as detailed metrics associated with system load and CPU, memory, network and file system utilization.

Profiles to Create Boot Environments

Ops Center now provides a new type of profile to automate the creation of boot environments. This makes it easier than ever before to set up live upgrade capabilities on a new OS instance.

Enhanced Update Management

We've introduced several improvements to greatly simplify the patch process. Ops Center now filters out redundant reboot operations, displaying a single reboot operation which would be performed during a multi-step patch process. In addition, OS update policies now provide an option to automatically filter out patches requiring an OS reboot.

Virtualization Management

Management of Oracle VM for X86

Ops Center now can discover Oracle VM Managers and use them to create and manage Oracle VM for X86 guests.

Creation Profiles for all Virtual Guest Types

In addition to Oracle VM server for SPARC, Ops Center now provides profiles and plans to create Oracle Solaris Zones and Oracle VM for X86 guests.


Server Pools for all Virtual Guest Types

All types of virtual assets can now be defined as part of a server pool: Oracle VM Server for X86, Oracle VM Server for SPARC, Solaris Zones for X86 and Solaris Zones for SPARC.

Expanded Storage Management Capabilities

Ops Center now supports storage management using iSCSI for Solaris. This allows Logical Unit Numbers (LUNs) to be dynamically created for any type of virtualized guest and made available through TCP/IP.

Management of Pre-Existing Zones and LDOM Guests

We've expanded the capabilities provided by Ops Center to pre-existing zones and Oracle VM Server for SPARC. This allows users to discover and manage existing virtualization environments.

Summary

Oracle Enterprise Manager Ops Center 12c has dramatically raised the bar for cloud and datacenter management. Hopefully, this article has provided a perspective on the many interesting enhancements available in this version of the product.
