TYPO3 Monitoring with Nagios

Nagios® is the industry standard in open-source server/service/network monitoring.

Use this software in combination with the TYPO3 extension "Nagios" to monitor your TYPO3 instances and get notified in the case of suspicious events, warnings, or fatal errors.

The TYPO3 extension gathers information about the TYPO3 system and exposes the data for a Nagios® server to retrieve. The Nagios® server parses and analyses the data and acts according to its configuration. A typical use case for Nagios® and the TYPO3 extension is to monitor a server farm with dozens of TYPO3 servers and to make sure that the infrastructure is fully functional, up-to-date, and secure.

The source code is available at GitHub.
