NagiosGrapher is an Open-Source tool which extends the monitoring software Nagios by automatically graphing performance data and embedding links to it into the Nagios web interface.

[edit] How it works

Nagios check plugins usually return strings containing extended information about the check result. NagiosGrapher filters out numeric data of check information by using regular expressions and stores it in an RRD databases. By storing filtered data, NagiosGrapher also extends the Nagios configuration and automatically embeds links into Nagios' web interface which lead to the performance graphs. It is also possible to browse and view performance charts via the NagiosGrapher web interface.

[edit] Features

To receive data, NagiosGrapher uses default interfaces provided by Nagios. New hosts and services integrated into the Nagios-monitoring infrastructure are recognized automatically and once data is stored via NagiosGrapher, the regarding links are embedded into the Nagios frontend.

Due to hook functionality, data can be stored in an SQL database, too. This enables the users to do further data processing of any kind. The hooks offer a powerful way to easily extend NagiosGrapher.
