Highlights

Redesigned Query Analyzer

The user interface of the Query Analyzer has been redesigned, improving navigation and introducing advanced configuration options.

Query Analyzer

It is now possible to customize the Query Analyzer graph and data visualization, sorting and filtering by clicking on Configure View button.

Configuration View

When you click on a SQL statement, the Statement Details page now lets you browse all example statements in the specified time range (rather than just being shown the one with the worst run time). Drill into any of these examples to see their individual statistics, literals used, and EXPLAIN plan.

Query Details

Scrolling down the page, graphs show you the execution pattern of the selected query during the specified time period. 

Query Graphs

MySQL Enterprise Monitor collects non-normalized examples of statement executions each minute when collecting aggregate statement statistics. You can visualize the latency of these Examples over the specified time period in the new Statement Distribution Chart. Each point on the chart represents a specific example statement execution time. Statements with an associated EXPLAIN plan are represented by a circle in the Distribution Chart. Points which are a square had no EXPLAIN plan captured for them. The red circle or square is the SQL statement that had the longest execution time for the specified period.

Example Statements

Clicking on a Statement Example within the Distribution Chart shows its query text in the original form, some additional execution context information, and its EXPLAIN plan.

Deleting Assets from the Inventory

The MySQL Enterprise Monitor Inventory user interface got a new functionality to remove assets. Now you can select and delete one or multiple entries for clusters, topologies, agents, hosts, and instances which were monitored, but are no longer in use.

Delete Confirmation

Note deleting assets only removes them from the inventory, and it does not remove or uninstall assets from their installed locations. 

New Views for Agents and Hosts

You can now examine the configuration and current status of Agents and Hosts in great detail.

The Agents view shows the MySQL Enterprise Monitor Agents currently registered with the MySQL Enterprise Service Manager.

Agents View

On a single screen, you see relevant information about the health of multiple agents, their versions, the number of assets monitored by each agent, last contact time, MySQL instances uptimes, versions, and data dir.

You can go further and check more details of a specific agent by selecting its More Info button.

Agent Details

The Agent details view displays JVM configuration and status, details on all MySQL connections, processes, instances, and detailed information on the host's operating system.

The Hosts view shows all currently monitored hosts and their configuration.

Hosts View

The Hosts view allows you to quickly inspect different hosts hardware configurations, their Operating Systems, number of filesystems, and number of monitored MySQL instances.

To drill-down and see more details of a host, select its corresponding More Info button.

Hosts Details

In the Host detail view, you see all the filesystems, the MySQL instances, and greater detail of the hardware configuration such as RAM, CPUs, and network interfaces.

Additional NDB Clusters Views

The new NDB Clusters configuration view complements the NDB Cluster monitoring with the visualization of all currently monitored clusters, their membership, and configurations.

NDB Clusters

The top-level list summarizes the NDB Cluster topology by displaying the number of Management, API and Data Nodes with their number of replicas. It also shows if the cluster is running on diskless mode.

To inspect the status and configuration details of the NDB Cluster nodes, select the More Info button.

NDB Cluster View

Memory Usage

The Global Memory Usage report builds upon the Memory instrumentation exposed within Performance Schema to provide greater insight into where memory is being allocated within the MySQL Instance - not just at the InnoDB Buffer Pool level, but for all memory allocations, across all connections and threads within MySQL. The report breaks down memory by allocation types, such as memory allocated for sorting, the buffer pool, or various other internal buffers used for statement processing.

MySQL Server 8

MySQL Enterprise Monitor 8.0 supports monitoring MySQL Server 8.0.11+, so you can monitor MySQL Server from version 5.5 onwards. MySQL Enterprise Monitor 8.0 also has MySQL Server 8.0 as its bundled repository or you can also use MySQL Server 8.0 as an external data repository.
