pgCluu is a PostgreSQL performance monitoring and auditing tool. It is a Perl program used to perform a full audit of a PostgreSQL
Cluster and System performance. It is divided in two parts:
- A collector used to grab statistics on the PostgreSQL cluster using the psql command line utility and sar from the sysstat package.
- A pure Perl grapher that will generate all HTML and charts output without any requirements.
If you don't need system utilization reports or don't want to install the sysstat package, you can disable it at command line. You will only have reports about your PostgreSQL Cluster. If you are running pgCluu from a central server using option -h to monitor remotely a PostgreSQL Cluster, the call to sar is automatically disabled.
If you just want to have system utilization reports or generate graphs from a sar data file, it's also possible.
