Re: [Nagios-users] puzzling no output from nrpe run of check_load

[David Harbaugh]

'su -' makes the shell a login shell ... which requires a real shell, not 
/bin/false.

What if you do this?

sudo su nagios more /proc/loadavg

Skip the -, which should run more directly, which should work even with 
/bin/false listed as the shell.

If that works, then you should be able to modify your nagios command definition 
the same way ...

Yes, ls -l /proc/loadavg shows:

-r--r--r--  1 root   root

which I believe mean any user can read it. 

Yet, 
sudo su - nagios more /proc/loadavg
returns nothing when the nagios user has /bin/false for a shell, and returns 
the expected output when the nagios user has /bin/bash for a shell.

I added the following line to /etc/sudoers:
nagios ALL=(ALL) NOPASSWD: /proc/loadavg
but that doesn't fix the problem.

thanks,
Peter

[Nagios-users] ServiceGroup Best Practices Question

[David Harbaugh]

I'm new to Nagios.  Running Nagios 3.2.3.

I want to start using Service Groups, but I'm not sure of the best place to put 
the service group definitions.

What is making me question the location is eventually I will want to create a 
service group that contains services hosted on both Linux and Windows machines, 
so I'm thinking of creating a new config file to hold the service groups, then 
in nagios.cfg use cfg_file= to load it in after the Windows and Linux machines 
are loaded.

Where do you create service groups?
