Percona Monitoring and Management 1.3.0Percona announces the release of Percona Monitoring and Management 1.3.0 on September 26, 2017.

Percona Monitoring and Management 1.3.0 introduces basic support for the MyRocks storage engine. There is a special dashboard in Metrics Monitor that presents the essential metrics of MyRocks as separate graphs. Also, Metrics Monitor graphs now feature on-demand descriptions that remain visible as long as hover over them.

For example, this graph helps you visualize MyRocks database operations of Next and Seek attributes:

There are many improvements to QAN (Query Analytics) both in the user interface design and in its capabilities. In this release, QAN starts supporting all types of MongoDB queries. For example, if you need to limit the list of available queries to only those that you are interested in, use the Query Filter field next to the database selection button:

Orchestrator is not enabled by default because leaving it in a non-configured state was confusing to users. It is still possible to enable it along with the docker run command.

For install and upgrade instructions, see Deploying Percona Monitoring and Management.
