Thank You to the Community!
We would like to mention some of the key contributors in this release, and thank the community for continued support of PMM:
- tcaxias for fixing our Docker deployment so that supervisor is PID 1
- pschultz who helped us improve the Disk Performance and Percona XtraDB Cluster graphs to better leverage Grafana tooltips
- Andrii Skomorokhov from Percona for fixing the Grafana tooltip bug #7708
- Tim Vaillancourt from Percona for a number of improvements to mongodb_exporter
New Dashboards and Graphs
This release includes the following new dashboards:
- MongoDB MMAPv1 dashboard provides insight for the MMAPv1 storage engine:
- MongoDB InMemory dashboard includes graphs related to the InMemory storage engine:
- MariaDB dashboard includes three new graphs for the Aria storage engine. There will be a detailed blog post about monitoring possibilities with these new graphs:
The new MariaDB dashboard also includes three new graphs for monitoring InnoDB within MariaDB. We are planning to move them into one of the existing InnoDB dashboards in the next PMM release:
- The InnoDB Defragmentation graph shows how
OPTIMIZE TABLEimpacts defragmentation on tables when running MariaDB with
- The InnoDB Online DDL graph includes metrics related to online DDL operations when using
ALTER TABLE ... ALGORITHM=INPLACEin MariaDB.
- The InnoDB Deadlocks Detected graph currently works only with MariaDB 10.1. We are planning to add support for MariaDB 10.2, Percona Server, and MySQL in the next PMM release.
- The Index Condition Pushdown graph shows how InnoDB leverages the Index Condition Pushdown (ICP) routines. Currently this graph works only with MariaDB, but we are planning to add support for Percona Server and MySQL in the next PMM release.
