Release Highlights

  • Backup Management can now be enabled from the UI. Go to Configuration → Settings → Advanced Settings, and you will see it in the Technical Preview section. We also added support for MongoDB services on-demand backup and restore. For now, it only supports ReplicaSet on S3-compatible storage.

  • Dashboards improvements

    • There are several community-driven improvements to ProxySQL data collection, with new dashboards to expose such metrics like: Queries Latency histograms and SHUNNED_REPLICATION_LAG state.

    • Fixes for Amazon Aurora service detection on the dashboard, MongoDB ReplicaSet Summary, and other MongoDB memory-related panels.

  • Improvements to DBaaS secrets by generating strong passwords for operators. This is an improvement to the Automated Operator Installation released in PMM 2.18, which will greatly enhance security.
