PostgreSQL: Statistics
Distribution	offizieller Teil von Check_MK
Lizenz	GPL
Unterstützte Agenten	Linux

This check handles the metrics returned from PostgreSQL's statistics functions {pg_stat_database} and {pg_database_size}. It allows monitoring of {disk blocks read}, but PostgreSQL seems to not have a simple "written bytes" or "write IOs" counter, meaning this information cannot be directly monitored. Instead, the check allows more fine-grained monitoring of database activity by tracking what the queries really do. You can monitor both "read statements" like {fetches}, as well as "write statements as {update/delete/insert}. Finally it allows monitoring of {commits}, which PostgreSQL tracks down to the sub-transaction level. You can then define levels on the per-second amount of the statements. This check relies on data reported by the agent-side plugin {mk_postgres}
