Hello Team,

We have upgraded nagios xi to latest version 5.5.5 post which check_nrpe nagios plugin updated to latest version 3.2.1 because of that we are facing issue in nagios for the exchange server memory usage, previeasuly memory usage alert will say only for committed memory, but right now we are getting alert for physical memory usage as well.

So as of now we don't need physical memory alerts in nagios also i have attached nsclient++ file for your reference.
Please help us out to over come from this issue.

[root@xxxxx]# ./check_nrpe --host xx.xxx.xxx.xxx --command check_memory
OK: committed = 29.455GB, physical = 27.6GB|'committed'=29.45488GB;57.57142;64.76784;0;71.96427 'committed %'=40%;79;89;0;100 'physical'=27.59968GB;38.37287;43.16947;0;47.96608 'physical %'=57%;79;89;0;100

If you didn't want to monitor the physical memory, you could specify the type to "committed" only. Also, you could use a warning and critical thresholds that make sense to you and your environment, in order to eliminate false alerts.

Example:

Code: Select all

[root@main-nagios-xi libexec]# ./check_nrpe -H x.x.x.x -c check_memory -a type=committed "warn=free < 2G" "crit=free < 1G"
OK: committed = 9.032GB|'committed'=22.88891GB;2;1;0;31.92112 'committed %'=72%;6;3;0;100

Hi Lmiltchev,

My bad, i have mentioned the flag wrongly so as per below command i have tryied and now we can able to see only the committed memory.

Before:
[root@xxxxxxx libexec]# /usr/local/nagios/libexec/check_nrpe -H x.x.x.x -p 5666 -c check_memory type=committed -a warn=used">"80% crit=used">"90%
CRITICAL: committed = 59.98GB, physical = 58.768GB|'committed'=59.98048GB;79.97141;89.96784;0;99.96427 'committed %'=60%;79;89;0;100 'physical'=58.76759GB;51.17287;57.56947;0;63.96608 'physical %'=91%;79;89;0;100

After:
[root@vwukm2sunix019_test libexec]# ./check_nrpe -H x.x.x.x -c check_memory -a type=committed warn=used">"80% crit=used">"90%
OK: committed = 30.218GB|'committed'=30.21777GB;57.57142;64.76784;0;71.96427 'committed %'=41%;79;89;0;100

Thanks for sorting out the problem, hence you can close the thread.
