PostgreSQL Database Last Vacuum and Analyze

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

This check allows you to monitor the last VACUUM and ANALYZE time for tables in a PostgreSQL database. You can configure limits specifiying the maximum age of the last operation. Without additional limits configuration this check is always OK.

This check relies on data reported by the agent-side plugin mk_postgres.

Check status:

For every table the time since it has last been analyzed or vacuumed is checked according to the WATO rule "PostgresSQL VACUUM and ANALYZE: Time since the last VACUUM" and "Time since the last ANALYZE" respectively. For tables that were never analyzed or vacuumed the time period for which they exist is checked according to the WATO rule "PostgresSQL VACUUM and ANALYZE: Age of never analyzed/vacuumed tables".

Discovery

Two services for each database. One for VACUUM and one for ANALYZE.
