I have found out the hard way that the only time Zenoss is a resource hog is when you are monitoring A LOT of devices.. when I am running htop it looks like it eats up the resouces due to the fact that it cannot write to mysql well enough.. I had 16000 devices doing SNMP trapping to it, and thats when I saw the issue. When being pushed this hard thats when you can see its limitations. When I was using it for only 300+ devices it was very good, but needed to be closely watched, since there are no watchdogs on the daemons and they get grumpy when busy. This was on a Dual proc quad core 3gHz box with 4 gigs of ram on it. For small to mid size installs with less than 1000 devices on a quiet network it will work really well from what I can see, and most of the bugs can be worked around. If you have a noisy network, and a lot of devices I dont believe that Zenoss is ready for it yet. It does not appear to be able to handle the loads on a single machine well enough, and I cannot find any real documentation on if it is possible to split out event monitoring to multiple installs, and still have an integrated front end for our NOC to use. It looks like Zenoss is going to have to be able to support a heavy SQL backend, as well as have process monitoring / restarting of its own daemons before this can really be considered Enterprise ready. I am really looking forward to seeing what the next major update will have. Currently I am running x2 2.0.2, and x1 2.0.3 side by side for perf managment only and they are working quite well for that, other than the zenperfsnmp processes dieing every once in a while. This happens on all 3 boxes, two with identical hardware and OS, and the third is only a dual proc with a gig of ram. They are watching ~500 devices currently, and I am going to load up the "light" box with all 16000 and see how the performance daemon behaves. Grin, this was a long response, to your question but hopefully there is some useful info in here... ------------------------ Christopher Hubbard -------------------- m2f -------------------- Read this topic online here: http://community.zenoss.com/forums/viewtopic.php?p=9140#9140 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
