• psutil ≥ 0.5.1

Installation from sources: setuptools ≥ 0.6.14

Installation

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

Notes

Length of SQL query text that pg_activity reports relies on PostgreSQL parameter track_activity_query_size. Default value is 1024 (expressed in bytes). If your SQL query text look truncated, you should increase track_activity_query_size.
