Getting to know check_postgres

Our friends at Bucardo created a useful, general-purpose PostgreSQL checking utility. The check_postgres tool currently has an inventory of more than 50 checks to monitor PostgreSQL servers.

While this is an exceptionally useful tool, integrating it into our overall stack is necessary to fully take advantage of its capabilities. This recipe will cover the basic usage and integration with Nagios for easy PostgreSQL monitoring of large database clusters.

Getting ready

Though some Linux distributions package the check_postgres utility for easy installation, the versions that are included are usually very old. We recommend that you obtain a copy of the latest check_postgres source code. At the time of writing this book, the latest version is 2.22.0, released on June 30, 2015. Obtain the latest copy of the check_postgres source code from this URL: https://bucardo.org/wiki/Check_postgres

Shaun Thomas

Shaun M. Thomas has been working with PostgreSQL since late 2000. He is a frequent contributor to the PostgreSQL Performance and General mailing lists, assisting other DBAs with the knowledge he's gained over the years. In 2011 and 2012, he gave presentations at the Postgres Open conference on topics such as handling extreme throughput, high availability, server redundancy, and failover techniques. Most recently, he has contributed the Shard Manager extension and the walctl WAL management suite. Currently, he serves as the database architect at PEAK6 Investments, where he develops standard operating procedure (SOP) guidelines to facilitate reliable server architecture among many other tasks. Many of the techniques used in this book were developed specifically for this extreme environment. He believes that PostgreSQL has a stupendous future ahead, and he can't wait to see the advancements subsequent versions will bring. https://www.linkedin.com/in/bonesmoses
