Statistics Views for Monitoring the Server

 

PostgreSQL: Important Statistics Views for Monitoring the Server

 In this post, I am sharing few important system or statistics views which we can use for monitoring the PostgreSQL Server.

We should monitor the different statistics of the server which help us for improving the overall database performance.

Below are few important views:

Return the running queries/connections information:

1

select * from pg_stat_activity 

Return the SSL information for each connection:

1

select * from pg_stat_ssl

Check the database statistics:

select * from pg_stat_all_tables

Check the system table statistics:

select * from pg_stat_sys_tables

Check the index statistics:
