Re: PostgreSQL 9.3: monitor read vs write activity

[Sergey Arlashin <sergeyarl.maillist@xxxxxxxxx>]

Thank you for your response and sorry for answering so late. Didn't have a chance to check it. 

But I cannot figure out how I can measure read vs write activity of my postgresql database with the help of "check_postgres"? I haven't seen anything related to it in "check_postgres --help" output. Moreover it seems I can get all the data that check_postgres provides simply by querying postgresql system tables like  pg_stat_database, pg_stat_user_tables, pg_stat_activity and so on. 

Let me explain. 

When I used MySQL I was able to measure read vs write activity by counting the number of selects vs inserts/updates/deletes etc. But I cannot find anything similar in PostgreSQL.

There are many monitoring system that provide this metricts like nagios,
munin, zabixx,... most of them rely on

Check the wiki http://wiki.postgresql.org/wiki/Monitoring

You can also do post monitoring by enable the logging and later running an analyser like pgbadger.
