I recently build my own Sophos UTM firewall based on the home license and wanted to get it under Zabbix monitoring. I’ve been using Zabbix for at least 8 years now and i recommend it as a (enterprise grade) monitoring system.
I’ve build an Template for public use, see: http://wouter.borremans.nl/computer-related-howto/programming/zabbix-monitoring-template-sophos-utm-firewall/
I’ve added an HOWTO to explain how to integrate Twitter’s Oauth authentication method with your own PHP pages. After batteling quite some time to get it working i decided to document a working approach to avoid future integration problems. Feel free to take advantage of the examples listed at this page: http://wouter.borremans.nl/computer-related/programming/php/twitter-oauth-integration/
