Monitoring MAC OS

[paulol]

Im monitoring some MAC machines with NRPE. I created the host and services with the wizard "MAC OS X" but the memory usage doesnt show anything, only swap.

What version of NRPE / Nagios Plugins are you using?

[paulol]

I downloaded from this link:

https://assets.nagios.com/downloads/nag ... ent.tar.gz

[hsmith]

Can you run this from the command line?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H IPADDRESSOFYOUROSXMACHINE -c check_mem -a '-w 10 -c 5'

[paulol]

[root@DOUAI libexec]# ./check_nrpe -H 192.168.0.71 -c check_mem -a '-w 10 -c 5'
OK: Memory Usage - % RAM, 19.82% Swap | phyUsed=%;10;5;0;100 swpUsed=19.82%;;;0;100

The "check_mem" uses the "check_osx_mem.sh" plugin. As far as I remember, this used to work. I am not sure what changed, i.e. a new version of "top" or "bc"... Log into the OSX box, run the following command, and show us the output:

Code: Select all

/usr/local/nagios/libexec/check_osx_mem.sh -v

[paulol]

Following the result.

I was able to recreate the issue:

Code: Select all

sh-3.2# ./check_osx_mem.sh -v
expr: syntax error
(standard_in) 1: parse error
pctPhyUsed=
(standard_in) 1: parse error
pctPhyAllUsed=
pctSwpUsed=60.05
rawOutput=0
pctWarning=
pctCritical=
pctSwpWarning=
pctSwpCritical=
OK: Memory Usage - % RAM, 60.05% Swap | phyUsed=%;;;0;100  swpUsed=60.05%;;;0;100

I spoke to one of our developers, and I was told that the plugin no longer shows the correct output, because of some changes made by apple. It will take some time before the plugin is fixed/patched.

I noticed that in addition to the issues I see (in my output), you also have an "illegal character: M" error. Did you try to modify this plugin in a text editor?

[paulol]

No, i didnt make any change in this files. I just downloaded and installed.

I see. I filed an internal bug report to our system (TASK ID 7839). It is up to our developers now to fix/patch the plugin. Thank you!
