Nagios is an open source tool that can be installed on SLES/OES that allows you to monitor your network and servers. The plugins attached are specifically written to monitor some of the functions of Open Enterprise Server and eDirectory, so you can remotely see how your server is performing. A big thanks to Novell Technical Services in Germany who contributed these scripts.
The wonderful thing about Nagios, is anyone with some scripting ability can write additional monitoring plugins. The intent here is that this will start as a good base of plugins and that other administrators would contribute additional plugins.
Send me a note if you have an additional plugin you have written to monitor SLES or OES and I'll update this thread with the additions. You can also post it separately on cool solutions as a tool and earn additional points!
It does look like you've done some collections from other projects, as well as included some new items. Some of what you've done addresses the same checks as those I created - you may wish to review mine for other ideas or for inclusion and improvement:
