Memory utilization not showing in HP-UX through NRPE

[lmiltchev]

You get a value for the PERCENTUSED variable just fine, and your command (run on the remote box) displays a percentage. So, the other possibility is that nagios user cannot run swapinfo (permissions issue) or doesn't have the full path to grep, sed or awk, which are used to determine the value of PERCENTUSED.

Code: Select all

PERCENTUSED=$(swapinfo -m | grep memory |  sed 's/'%'//' | awk ' { print $5 }')

Can you run the same command on the remote machine but as nagios user and show the output?

Code: Select all

su - nagios
/usr/local/nagios/libexec/check_mem -w 80 -c 90

Hi Team,

We have run those command with Nagios user and we were getting desired output, i"ll share the snapshot soon please suggest what need to be done next.

[lmiltchev]

Let's verify the output of the following commands:

On the Nagios XI server:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H <remote ip> -c check_mem -a '-w 80 -c 90'

On the remote machine:

Code: Select all

su - nagios
/usr/local/nagios/libexec/check_mem -w 80 -c 90

We have shared the output with nagios user only and yes nagios user is able to run this plugin and getting output with percentage details. no problem in doing this on server with nagios user also.

Only NRPE is not able to fetch the details its only showing OK without no. in percent no matter if the output is in critical state or in warning state it will only show OK.

I don't see it anywhere... You showed us the command run as "root":

HSOLMANDEV:/usr/local/nagios/libexec #./check_mem -w 80 -c 90
OK - System Memory is at 10% |memory=10;90;80;00;80
HSOLMANDEV:/usr/local/nagios/libexec #

HSOLMANDEV:/usr/local/nagios/libexec #/usr/local/nagios/libexec/check_mem -w 80 -c 90
OK - System Memory is at 10% |memory=10;90;80;00;80
HSOLMANDEV:/usr/local/nagios/libexec #

Am I missing something?

Hi Team,

Appoligies from our end.

Yes Nagios user is not able to run the command we were doing it wrong,

please find below output

$ /usr/local/nagios/libexec/check_mem -w 80 -c 90

===========================================================


we have tried to give permission on swapinfo command

HSOLMANDEV:/ #which swapinfo
/usr/sbin/swapinfo
HSOLMANDEV:/ #ll /usr/sbin/swapinfo
-r-sr-xr-x 1 bin bin 77428 Nov 28 2013 /usr/sbin/swapinfo
HSOLMANDEV:/ #

but no success.

still nagios is not able to run the command.

[lmiltchev]

Try adding the following line to sudoers:

Code: Select all

nagios ALL=NOPASSWD: /usr/sbin/swapinfo *

then test running the check again with sudo, logged in as nagios user:

Code: Select all

su - nagios
sudo /usr/local/nagios/libexec/check_mem -w 80 -c 90

If it works, you can change your command in the nrpe.cfg file by adding "sudo" to it.

Code: Select all

command[check_mem]=sudo /usr/local/nagios/libexec/check_mem $ARG1$

[progressive.nagiosXI]

the first time sudo required nagios password which we have not set as its using by NRPE,

is there any default password??

[lmiltchev]

No, there is no 'default' password for the nagios user. Did you add the following line to sudoers on the remote machine?

Code: Select all

nagios ALL=NOPASSWD: /usr/sbin/swapinfo *

It is strange that it is asking you for a password...

Hi Team,

This is working the only problem was this that in the plugin check_mem command 'swapinfo' was getting used directly not with pure path ' /usr/sbin/swapinfo'

so the problem in HP- UX was this that root user is able to run the command by juust typing swapinfo but rest of the users need to type the exact path of this /usr/sbin/swapinfo

Thanks team.

Thanks
