Percona Monitoring and Management 2.36.0

Release date: Mar 23, 2023
Installation: Installing Percona Monitoring and Management

Percona Monitoring and Management (PMM) is an open source database monitoring, management, and observability solution for MySQL, PostgreSQL, and MongoDB.

Release Highlights

pg_stat_monitor 2.0 support in QAN

We are excited to announce PMM 2.36 now supports pg_stat_monitor 2.0 (PGSM 2.0) in QAN, a powerful PostgreSQL query performance monitoring tool. By downloading this update, you will have access to the latest improvements and fixes covered by PGSM2, including:

  • Improved internal architecture that results in fewer lock acquisitions and increases performance by approximately 20%.
  • Support for PostgreSQL 15
  • Enhanced consistency with pg_stat_statements so that the pg_stat_monitor view has identical column names, columns, and data types as pg_stat_statements for every major version of PostgreSQL from versions 11 to 15.
  • A bucket status indication (done vs. current) eliminates the need for the tool to evaluate bucket status and facilitates accurate data display.
  • The generation of a unique ID for a query makes it easier to monitor query planning, execution, and performance regardless of version, database, user, or schema.

For more information on the enhancements in PGSM2, refer to the full list.


PMM 2.36 and PGSM 2.0 now support PG 13, 14, and 15. Support for older versions (PG 11 and 12) will be introduced in PMM 2.37.

Revamped Advisors page

We’ve improved the structure of the Advisors page to group Advisors by categories and clearly show the Advisors available for your current subscription.

With this change, we have renamed all the tabs on the page, and added an option to easily integrate with Percona Platform for extra Advisors for free:


PostgreSQL Advisors executed against more databases (DBs)

To give you additional insights on your PostgreSQL DBs, PostgreSQL Advisors now try to perform checks on all the databases accessible with the credentials used during pmm-client setup. In most cases, these are the databases available for the PMM database account user. For more information, see the Create a database account for PMM topic in the PMM online Help.”

Backup Management enabled by default

Since the PMM 2.32 release, we have continuously improved the Backup Management functionality in terms of backup locations, restore options and user experience.

As a mature and generally useful feature, this option is now enabled by default for easier access to your backups and restore artifacts.


  • Upgrading to PMM will automatically enable this feature for existing PMM instances. You can disable it at any time from your PMM dashboard on the Advanced Settings page or using the Docker environment variable DISABLE_BACKUP_MANAGEMENT=1.
  • While we have GA’ed Backup Management for MongoDB since PMM 2.32, Backup Management for MySQL still in technical preview, and, therefore, subject to change. For more information, see the Percona Release Lifecycle.

Components upgrade

Grafana has been upgraded to version 9.2.13.

New Features

  • PMM-9474 - PostgreSQL Advisors are now executed against all the available databases (DBs), not only the one connected to PMM
  • PMM-11363 - Starting with PMM 2.36.0, you no longer need to unassign a role before deleting it. If you try to delete a role assigned to a user, you will see a dropdown with replacement roles. As a result, the selected role will be assigned to the user.


  • PMM-11640 - [Backup Management]: The Backup Management feature is now enabled by deault forf easier access to your backups and restore artifacts.

  • PMM-11182 - [Platform integration]: Renamed the Disconnect button on the confirmation message that pop-ups when you are terminating Percona Platform connections as an Administrator. The button is now called Force disconnect to better differentiate between situations where you are disconnecting using a Percona Platform Account.

    Force-disconnecting only clears the connection in PMM without automatically removing the disconnected servers from Percona Platform. We recommend that you always disconnect while logged in with your Percona Account. Otherwise, make sure to manually remove the force-disconnected servers from your list of PMM instances in Percona Platform.

  • PMM-11381 - Starting with PMM 2.36.0, you can scrape Kubelet metrics with DBaaS or VictoriaMetrics operator. Using Kubelet metrics, you can gather volume-related information.

  • PMM-11566 - You now have Admin Access to PMM Demo instances so that you can experiment with all the features of PMM.

  • PMM-11699 - Improved documentation and descriptions for Advisor checks.

  • PMM-10974 - Usage of pg_stat_monitor by default.
