Percona Monitoring and Management 3.9.0 has been released

We're excited to announce the release of Percona Monitoring and Management 3.9.0, available since Thursday, July 30, 2026.

This release adds a new Alert Status page for viewing all active alerts by node or service, new MongoDB and PostgreSQL dashboard panels, and CSV export for Real-Time Analytics (RTA) data.

It also removes the provisioned PostgreSQL datasource as a security measure, adds Ubuntu 26.04 LTS support for PMM Client, and completes the removal of UI-based PMM Server upgrades announced in PMM 3.8.0.

Get hands-on with PMM 3.9.0 by setting up your instance using our quickstart guide.

Here's a summary of the main changes in this release:

• Alert Status page (Alerts > Status) for viewing every active alert affecting a node or service in a single view, with filtering by state and direct silencing from the table
• Removed provisioned PostgreSQL datasource to prevent Viewer-role users from running arbitrary SQL against PMM's internal database — you can still add it manually if needed
• Data size panels for MongoDB on the ReplSet Summary and Sharded Cluster Summary dashboards to track current data size and growth over time
• Disable collectors field in the Add service form for MySQL, PostgreSQL, MongoDB, and ProxySQL, so you can exclude specific collectors without modifying the exporter configuration
• Four new PostgreSQL Top Queries panels for identifying queries causing high CPU, memory, I/O, and shared block read pressure
• CSV export for Real-Time Analytics data to preserve a snapshot of in-progress query data that would otherwise be lost when queries are killed before finishing
• UI upgrade functionality removed. Upgrade PMM Server using Docker, Podman, or Helm from the command line
• Ubuntu 26.04 LTS support for PMM Client on AMD64 and ARM64, including Percona Distribution for PostgreSQL 18, Percona Server for MySQL 8.4, and Valkey 9.1
