Release Highlights

  • Backup Management can now be enabled from the UI. Go to Configuration SettingsAdvanced 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.
