HI Team,
Actually, we installed our Nagios XI Server, Offloaded MYSQL Server and Incident Manager servers on VMware ESXi boxes....
We are guessing the problem would be with "iowait" and also thinking the problem may be with storage IOPS... Can u pls suggest us whether i am right on that...
and i am attaching my free -m output for youre reference,...

Re: Nagios XI Performance Issues-RAM Utilization
It looks like 10gb of the 12gb of memory in use are used by disk buffers. Essentially, this means that nagios is using 2gb or less of ram and the kernel is allocating 10gb to disk buffers. So no problem there.
The top output you posted showed oi wait at 0%. You may want to run top for a while, checking the io wait for spikes . . .anoop wrote:We are guessing the problem would be with "iowait" and also thinking the problem may be with storage IOPS... Can u pls suggest us whether i am right on that...
