Top new features of Oracle Enterprise Manager App for Grafana v2.0.0
We are excited to announce the second major release of Oracle Enterprise Manager (EM) App for Grafana version v2.0.0. This version includes several new features and performance enhancements:
Dashboard for WebLogic Server Performance Summary
The image below is a screenshot of the WebLogic Sever Performance Summary Report dashboard. It has pre-defined panels for WebLogic metrics, such as CPU, Heap, Memory Pool, Active Sessions or Garbage collection, which are the metrics collected by Enterprise Manager.

Build dashboard panels for String based metrics columns
This feature is used to show configuration information on a dashboard without writing a query. EM Metrics sub-system collects numeric performance information like “Total Archive Used (%)” and text information such as “Automatic Archiver” status “Started, Stopped, Failed”. Another example would be the value for metric “Database Status”, which could be “Active, Suspended, Instance Recovery”. Version 2.0 of the EM Grafana plugin lists down the configuration type text metric information to be shown on a dashboard.

Highlight SQL Syntax for better readability

This helps speed up the time required to get context of a query, spot issues or modify sub part of a long complex query.

Build dashboards from data collected using Metric Extension. This lets you build charts that are unique to your IT environment.
Knobs to throttle the Grafana REST API usage. This helps prevent overuse of the API that in turn can compromise the operational performance of key EM subsystems.
EM RU version compatibility checker to help identify any compatibility issues. This version is certified with Grafana version 7.3 and EM version 13c Release 4 Release Upgrade 7+.
Additionally, we would like to highlight the “Access Remote Repository” on the App’s Data Source page. It allows to create dashboards on pre 13.4 version of EM in your environment.

Below are the steps for setting up Remote Repository Data Source as shown in Figure 5.
- Host and Port where the remote repository resides.
- SID or Service Name of the remote repository.
- Named Credential the App will use to log in to the remote repository. Note: The named credential must be a Global Named Credential that has already been defined in Enterprise Manager.
These Global Named Credentials must be defined in Enterprise Manager Release 13.4, Release Update 3 and above only. For more information about Global Named Credentials, see Named Credentials in the Enterprise Manager Cloud Control Security Guide. See Figure 5 above for more details.
For detailed explanation on installation, upgrade, and usage, refer to the Oracle Enterprise Manager App for Grafana User’s Guide. Note: Grafana API are disabled by default and need to be enabled using the OMS property “oracle.sysman.db.restfulapi.grafana.enable”
The EM App is an example of Oracle’s ongoing commitment to extend the use of Oracle Enterprise Manager via various extensibility mechanisms.
