Hello everybody,
We've been running a Zenoss server for more than two years and now the time has come to migrate it on a new server and at the same time upgrade to the latest version of Zenoss. Unfortunately we are being pressed into running Zenoss on a virtual server and I'm expecting to be plagued by performace problems.
Up to this time we have been running on an IBM X series with 16GB of RAM, 1 Intel dual-core CPU and a RAID 5 made of 7K RPM disks.
I noticed that hardware requirements are based on the number of devices being monitored but that does not work very well for our environment. We are using Zenoss to monitor networking equipments only, 200 devices (switches, routers and firewalls) having close to 44000 interfaces (in excess of 350000 data sources) being polled and graphed, and planing to add more devices. At this point the disk usage is impacting the performance with CPU waiting for IO an average of 20% with bursts up to 80% but the server still shows an acceptable response time. The big mistery is how is this going to work in a virtual server and here I have a couple of questions.
* Is anyone running Zenoss on a virtual server for the same kind of environment (low number of devices but high number of datasources) and if yes, are there any issues I will have to address in terms of virtual environment configuration (VMware) ?
* Even if applying the recommended fine-tuning for storage might help improving the situation a little bit, I doubt the server could take an additional 50 networking devices and the fact that the server will be using a shared storage will surely not bring a performance boost so what other options do IÂ have ?
