## pgCluu, PostgreSQL Cluster Utilization

pgCluu is a Perl program used to perform a full audit of a PostgreSQL Cluster performances. It is divided in two parts, a collector used to grab statistics on the PostgreSQL server using psql and sar, a reports builder that will generate all HTML and charts output.

New or enhanced reports/features:

* Add collect and report of unused trigger functions.
* Add system statistics dedicated to PostgreSQL process through stats reported by pidstat.
* Add report of CPU scaling_governor to check if it set to powersave, setting it to performances can improve performances up to 20% following the PostgreSQL load. For more information on this kernel parameter see [](

New command line options:

* Add command line option -t | --lock-timeout with default to 3 seconds to self terminate a SQL query that could be lock by the activity of an other session like a drop table for example.

New configuration directives :

* Add STATS_REPORT_OUTDIR configuration directive to pgcluu.conf to set the directory where the pgCluu reports will be saved. Default to /var/lib/pgcluu/report/.

Backward compatibility:

- Change default retention time to 30 days instead of no storage limit to avoid possible out of memory on uncontrolled installation.

See [ChangeLog]( for a complete list of changes and bug fixes.

## About

The goal of this project is to provide a complete PostgreSQL auditing tool that don't need any dependency to be run easily to audit a local or remote server.

If you just have a sar output file, pgCluu can also be use to draw graphs about the system utilization from this file.

pgCluu is a collection of tools published under the PostgreSQL License to be shared, any one is welcome to contribute.
