The difficulty with Zenoss is that it can become very I/O bound. We are monitoring 640 devices and about 20.000 data points on an old dual Xeon single core server with 4 GB of RAM. Main reason why we are currently in the process of upgrading to a new dual quad core system with 16 GB for Zenoss isn't that we urgently need more CPU power or more RAM. The reason is that Zenoss currently is roasting the two mirrored 72 GB disk it uses for data storage. 20.000 data points means updating 20.000 RRD files every 5 minutes and if your storage isn't able to handle that kind of load your Zenoss system will become very sluggish and unresponsive. So my advice for anybody who wants to monitor lots of data points in Zenoss is: Get the best storage system you can effort and don't settle with anything less than a RAID 5 with battery buffered write cache. Once you have done that choose the CPU and RAM size that fits the price category of your storage system and you should end up with a decent Zenoss system for you needs. -------------------- m2f -------------------- Read this topic online here: http://forums.zenoss.com/viewtopic.php?p=29183#29183 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
