Some time ago, I created a video and wrote a blog on a quick and painless way to install the LINUX agents for SCOM. Well, came time to do that again and I noticed, even after downloading the management packs from the catalog, I could not find the rpm files!
After some exasperating searching and much gnashing of the teeth, I finally found the download for the updated management packs. Installing the ones from this pack will give you the rpms. In the past, the rpms could be found on the CD/DVD.
