Percona Monitoring and Management 3.7.1 has been released
We're announcing the release of Percona Monitoring and Management 3.7.1, available since Thursday, April 30, 2026.
This is primarily a security release. It fixes several CVEs in third-party dependencies, upgrades Grafana, Nomad, and VictoriaMetrics, and masks database credentials in logs to make log sharing safer. It also adds a MongoDB storage fragmentation view, makes PMM Client setup more flexible for containerized environments, and fixes issues in Real-Time Analytics, dashboards, and exporters.
Get hands-on with PMM 3.7.1 by setting up your instance using our quickstart guide.
Here's a summary of the main changes in this release:
- MongoDB storage fragmentation analysis — the MongoDB Cluster Summary and MongoDB ReplSet Summary dashboards now include a Fragmentation Analysis panel showing the ratio of free to allocated storage per collection
- Automatic credential masking in logs — PMM now masks database passwords and connection-string credentials in logs, so you can share logs for troubleshooting without exposing sensitive values
- Flexible PMM Client setup for containers — use the new
--proc-mounts-pathflag orPMM_AGENT_SETUP_PROC_MOUNTS_PATHenvironment variable to tell PMM Client where to find/proc/mountsin non-standard environments - Security fixes addressing a gRPC authorization bypass (CVE-2026-33186), a Grafana SQL expressions remote code execution vulnerability (CVE-2026-27876), and multiple Go standard library vulnerabilities
- Key components upgraded: VictoriaMetrics v1.140.0, Nomad v2.0.0, Grafana 11.6.14, and Grafana ClickHouse Datasource v4.15.0
