Nagios Support Forum

Hi Scott,
meanwhile in the bat cave... , working on another plugin..... check_dirsize.

Works fine on the commandline, but not trough nrpe ...

Commandline on the remote server:

./check_dirsize -d /ConnectionsContentStoreLink/blogs/upload/f/b/c/fbc40af7-f364-4114-bd59-6cdddd04f6d0/BLOGS_UPLOADED_IMAGES -w 2000 -c 2048 -f
1698 MB - ok|'size'=1698MB;2000;2048

On the nagios-server commandline:

./check_nrpe -H linux-host -c check_dirsize -a '-d /ConnectionsContentStoreLink/blogs/upload/f/b/c/fbc40af7-f364-4114-bd59-6cdddd04f6d0/BLOGS_UPLOADED_IMAGES -w 2000 -c 2048 -f'
Error: invalid option -- 'w' /usr/bin/du

nrpe.cfg:
command[check_dirsize]=/usr/lib64/nagios/plugins/check_dirsize -d '$ARG1$' -w '$ARG2$' -c '$ARG3$' -f

Tried several options in the nrpe.cfg, but did not get it to work....

change this to this

Hmm, it may have to be set on the first time it is loaded.

I can only suggest not sending a passive result setting the status to OK

Hi Scott,
in the nagios web interface, you can force execute the check. After done that, the state Pending was not showing anymore.

to this

Hi Scott,
i made the adjustment. I am getting an other message now:

-bash-4.2# ./check_nrpe -H linux-server sudo su - -c check_dirsize -a '-d /ConnectionsContentStoreLink/blogs/upload/f/b/c/fbc40af7-f364-4114-bd59-6cdddd04f6d0/BLOGS_UPLOADED_IMAGES -w 2000 -c 2048 -f'
Error: Permission denied

The check trough the commandline on the linux-server works fine..

-bash-4.2# ./check_dirsize -d /ConnectionsContentStoreLink/blogs/upload/f/b/c/fbc40af7-f364-4114-bd59-6cdddd04f6d0/BLOGS_UPLOADED_IMAGES -w 2000 -c 2048 -f
1698 MB - ok|'size'=1698MB;2000;2048

Do i have to do something with sudo...?

Regards, Paul.

Can you show the permissions of these

In order to allow the nagios user to read from that directory you either need to make it readable to others or add nagios to the wasadmin group

chmod o+r /ConnectionsContentStoreLink/blogs/upload/f/b/c/fbc40af7-f364-4114-bd59-6cdddd04f6d0/BLOGS_UPLOADED_IMAGES

or add nagios to the wasadmin group

I have done chmod o+r, the error message changed to Error: permission denied /usr/bin/du

I have got it to work; added this to /etc/sudoers.d/ 040_nrpe_dmgr

nrpe ALL = (wasadmin) NOPASSWD: /usr/bin/du
nrpe ALL = (wasadmin) NOPASSWD: /usr/lib64/nagios/plugins/check_dirsize -d /ConnectionsContentStoreLink/blogs/upload/f/b/c/fbc40af7-f364-4114-bd59-

6cdddd04f6d0/BLOGS_UPLOADED_IMAGES -w 2000 -c 2048 -f

nrpe.cfg:

command[check_dirsize]=sudo -u wasadmin /usr/lib64/nagios/plugins/check_dirsize $ARG1$

Is this the correct way to do it?

Paul.

Glad to hear you got it working
