Nagios Support Forum

Hi Team,

We have observed that the memory utilization on our Nagios XI servers (4 servers) is mostly high. I am attaching the screen shots here.
Please check and let us know if this much of utilization is fine or we need to add more memory.

This is normal on a Linux server, the bulk of the memory is actually Cached for fast recall of recent used data.

There is no need to add additional memory with this type of usage.
