Hi We have an esx pool of about 120 VMs, and about 4-5 service checks per vm (disk/stock web/ssh/ldap/ssl certificate expiry/tomcat web apps/etc etc). The nagios monitor (also a vm) hits them all. Only ‘unique’ issue we have since the vms are in a really aggressive load balancer, outages in ne

I would be very very wary of running Nagios on a VM (we use VMware here). The reason for this is Clock Skew. Clock Skew causes the virtual clock on the guest OS to lag behind then skip forward depending on the loading and sleep times of the guest. Note that this will not affect 'Para-virtuali

This definitely a question of scale. I suspect a virtual solution could support a couple thousand services or even more in a distributed environment. For a smaller environment it would be a no-brainer. We virtualize everything by default so the next nagios server will go virtual in our MS Hyper-

This was a year or two ago, but we found that when we ran Nagios in this way it worked in general, but because of the sort of variable size of a second on VMware, the latencies were kind of screwed up. This was clearly evidenced when we looked at the performance statistics. Nagios indicated th

Hello people, I would like to know if it is advisable (or best practice) to install and run a Nagios monitoring server on a virtual machine (in this case, with OpenSuSE as the OS) with the intention of monitoring physical hardware client machines on the same LAN. If so, what known issues should I
