Command line tool for PostgreSQL server activity monitoring.

  • psycopg22.2.1
  • psutil0.5.1

Installation from sources: setuptools0.6.14

sudo python setup.py install

Usage

pg_activity works localy or remotely. In local execution context, to obtain sufficient rights to display system informations, the system user running pg_activity must be the same user running postgresql server (postgres by default), or have more rights like root. Otherwise, pg_activity can fallback to a degraded mode without displaying system informations. On the same way, PostgreSQL user used to connect to the database must be super-user.
ex:

sudo -u postgres pg_activity -U postgres
