Percona Monitoring and Management 1.6.0

    January 18, 2018

Percona announces the release of Percona Monitoring and Management 1.6.0. In this release, PMM Grafana metrics are made available in the Advanced Data Exploration dashboard. The integration with MyRocks has been improved and its data are now collected from SHOW GLOBAL STATUS.

The MongoDB exporter now features two new metrics: mongodb_up to inform if the MongoDB Server is running and mongodb_scrape_errors_total reporting the total number of errors when scraping MongoDB.

In this release, the performance of the mongodb:metrics monitoring service has been greatly improved.

PMM 1.6.0 also includes version 4.6.3 of Grafana which includes fixes to bugs in the alert list and in the alerting rules.

New Features

  • PMM-1773: PMM Grafana specific metrics have been added to the Advanced Data Exploration dashboard.


  • PMM-1485: Updated MyRocks integration: MyRocks data is now collected entirely from SHOW GLOBAL STATUS and we have eliminated SHOW ENGINE ROCKSDB STATUS as a data source in mysqld_exporter.
  • PMM-1895: Update Grafana to version 4.6.3:
    • Alert list: Now shows alert state changes even after adding manual annotations on dashboard #9951
    • Alerting: Fixes bug where rules evaluated as firing when all conditions was false and using OR operator. #9318
  • PMM-1586: The mongodb_exporter exporter exposes two new metrics:
    • mongodb_up informing if the MongoDB server is running and
    • mongodb_scrape_errors_total informing the total number of times an error occurred when scraping MongoDB.
  • PMM-1764: Various small mongodb_exporter improvements
  • PMM-1942: Improved the consistency of using labels in all Prometheus related dashboards.
