Nagios Support Forum

I have an Ubuntu 10.10, and Nagios 3.5.1, and MKlivestatus. At the beginning my ram memory has nearly 50% free (I have 1GB ram). But, day by day, the memory is been consumed. After 5 days working, my system has only 10% memory free, and swap starts working logically. How Nagios increase the use of ram memory? Nagios are sending pings and snmpget commands to 44 different machines (no one are accesible, it´s a test). Why continue consuming memory? Is a problem with MKLivestatus?
Thank you in advanced.

Can you run the "top" command and post a screenshot or the actual output?

Possibly. What does the ram usage look like? What process name is mostly to blame? Are the nagios forks for checks hanging?

This is a screenshot

When you restart nagios does your unassigned memory reset to a more suitable number?

When I restart Nagios, memory goes from 164KB free to 262kB free, but at the begining my system had 500KB free. Day by day my memory continues reducing my free memory. I attach two snapshot, one before de restart Nagios, and the other after restart Nagios.
It should be the use of mklivestatus...
Thank in advanced.

And this is the snapshot after restart...

Lets check the amount of ram that is used for disk buffers: Could you also run:

After 7 days working I did your commented command: free -m
As you can see I think I´m losing buffers day by day (or is not used).
Thank you.

It looks like you only have around 200mbs free after buffers. It the server load/memory spikes, you start using swap. Can you increase the provisioned ram for this vm?
