SUSE Linux Enterprise 10 – Monitoring the online patch updates with Nagios through SNMP
|
|  |
Automating the the watch for new online patch updates is extremly helpful.
Especially when it is integrated into a existing Monitoring and notification
tool like Nagios, it eliminates the need to explicitly check each systems
updater icon through direct logon. There are already descriptions on
the web that explain such a setup for Redhat and Debian Linux in detail.
Below is the modification to make it all work for with SUSE Linux
Enterprise Server 10 (SLES10 SP2).
