history

Project history and usage

check_postgres is a Perl monitoring plugin for PostgreSQL, designed primarily for Nagios but also documenting MRTG, Cacti, and simple output modes.

Project history

The script copyright begins in 2007 under Greg Sabino Mullane. Its GitHub repository was created in May 2009, and the embedded documentation describes many PostgreSQL actions, output modes, rc-file support, and mailing lists for announcements and general development.

Adoption history

The README gives both a quick Nagios-script installation path and a standard Perl Makefile.PL build path. The batch input records packaging across Homebrew, Alpine, Debian, Ubuntu, Fedora, and openSUSE families.

How it is used

Administrators use check_postgres actions to monitor connections, locks, bloat, replication, database size, transaction age, settings checksums, pgbouncer state, and many other PostgreSQL operational signals.

Why package nerds care

check_postgres is a classic ops package: a single Perl monitoring tool with many symlink-friendly subcommands, Nagios exit codes, packageable docs, and long-running compatibility concerns around PostgreSQL client binaries and credentials.
