Nagios Support Forum

I have the Nagios Agent installed on Linux servers. It appears that the numbers do not match (see attached screen print). How does the agent calculate memory?

Can you share the /usr/local/nagios/etc/nrpe/common.cfg from the remote server as well as the configuration for this service?

As requested...

Can you also share the configuration for this service in XI?

Sorry for the delay in responding. Can you share with me how to export the config?

Configure -> CCM -> Services
Click on the "View Config" icon next to this service.

then find the definition for this service name

Sorry, didn't realize you just wanted a copy of the config file. Changed hostname & ip along with notified users for proprietary reasons.

this all looks correct.

I'm looking at your first post and what do you not think is correct?

The server has 43082744 bytes memory, which is 42072 MB

Thanks Scott... I will forward to my Linux Admin who was questioning this. I will get back to you.

Sounds good
