pg_monz (PostgreSQL monitoring template for Zabbix) is a Zabbix template for monitoring PostgreSQL. It enables various types of monitoring of PostgreSQL such as alive, resource, performance, etc. Pg_monz also supports automatic discovery of databases and tables using the discovery feature of Zabbix and can automatically start monitoring.
The following is a summary of the major changes.
pg_monz 2.0 now supports monitoring of Streaming Replication which is embedded in PostgreSQL since 9.0.
Various monitoring items such as Primary / Standby servers alive monitoring, delay of replication data propagation and conflicts occurred by operation to Primary and Standby are available.
It is also that a trigger which can detect the occurence of write block query when useing synchronous replication is provided.
Monitoring items are grouped by each application to clarify them.
The following are main applications.
| application name | summary of monitoring |
|---|---|
| pg.transactions | Connection count, state to PostgreSQL, the number of commited, rolled back transactions |
| pg.log | log monitoring for PostgreSQL |
| pg.size | garbage ratio, DB size |
| pg.slow_query | slow query count which exceeds the threshold value |
| pg.sr.status | conflict count, write block existence or non-existence, process count using Streaming Replication |
| pg.status | PostgreSQL processes working state |
| pg.stat_replication | delay of replication data propagation using Streaming Replication |
| pg.cluster.status | PostgreSQL processes count as a cluster |
Previously, pg_monz accesses the monitoring DB every when gathering one monitoring item about DB, which may affect the performance of monitoring DB. With this update, to reduce the frequency of DB accesse, pg_monz gathers collectable monitoring items all at once.
pg_monz requires the following software products:
- Zabbix server, zabbix agent, zabbix sender 2.0 or later
- PostgreSQL 9.2 or later
Please see the included quick-install.txt.
pg_monz 2.0 does not have backward compatibility with the 1.0. When upgrading from 1.0, please install the new version again.
