Percona Monitoring and Management 1.1.4

  • Date

    May 29, 2017

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

This release includes experimental support for MongoDB in Query Analytics, including updated QAN interface.

Query Analytics for MongoDB

To enable MongoDB query analytics, use the mongodb:queries alias when adding the service. As an experimental feature, it also requires the --dev-enable option:

sudo pmm-admin add --dev-enable mongodb:queries

Note

Currently, it monitors only collections that are present when you enable MongoDB query analytics. Query data for collections that you add later is not gathered. This is a known issue and it will be fixed in the future.

Query Analytics Redesign

The QAN web interface was updated for better usability and functionality (including the new MongoDB query analytics data). The new UI is experimental and available by specifying /qan2 after the URL of PMM Server.

Note

The button on the main landing page still points to the old QAN interface.

You can check out the new QAN web UI at https://pmmdemo.percona.com/qan2
