✨ Release highlights¶

Disable individual metric collectors per service¶

PMM 3.9.0 adds a Disable collectors field to the Add service form for MySQL, PostgreSQL, MongoDB, and ProxySQL. You can now exclude specific metric collectors from collection without removing the service or modifying the exporter configuration.

This is useful when certain collectors generate metrics you don’t need, add overhead on resource-constrained hosts, or cause issues with specific database configurations.

Disable collectors field in Additional options

To use it, go to PMM Configuration > Add Service, expand Additional options, and enter a comma-separated list of collector names in the Disable collectors field.

For the full list of available collectors per database type, see Connect MySQL databases to PMM and Connect PostgreSQL databases to PMM.
