Percona Monitoring and Management 1.3.0

  • Date

    September 26, 2017

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

In release 1.3.0, Percona Monitoring and Management introduces a basic support for the MyRocks storage engine. There is a special dashboard in Metrics Monitor where the essential metrics of MyRocks are presented as separate graphs. And Metrics Monitor graphs now feature on-demand descriptions.

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.

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.

  • PMM-1314: The selected time range in QAN could be applied incorrectly. This problem is not observed in the new design of QAN.
  • PMM-1398: The Prometheus server was not restarted after PMM was upgraded. This bug is now fixed.
  • PMM-1427: The CPU Usage/Load graph in the MySQL Overview dashboard was displayed with slightly incorrect dimensions. This bug is now solved.
  • PMM-1439: If the EXPLAIN command was not supported for the selected query, there could appear a JavaScript error.
  • PMM-1472: In some cases, the monitoring of queries for MongoDB with replication could not be enabled.
