Yes I agree with Ed as well on the remote stuff -
And yes, the *nix OS determines what shell/program (eg perl/bash/sh/zsh etc) to
execute the script with by the shebang line in the top of the file, and whether
or not it's executable.
I would definitely try and execute it as the nagios user - that is all that is
left in your case it seems (?)

If this is run on a remote host using nrpe this what I would check:
- type "which bash" on the remote host and make sure the path matches what's in
your script.
- verify your nrpe.cfg has an entry in it for your script I.e "check_myscript"
- verify on the master that check commands matches the remote entry

Actually I verified that this script runs fine manually using default (Bourne)
shell too.
So now I have "#!/bin/sh" in the beginning of my script and it still is not
being picked up by service.
And I restart Nagios to initiate the service attempt.
Do you refer to Bourne shell ("#!/bin/sh" ) in this part of your explanation:
“ (If it's a shell script, nagios will execute it using the proper interpreter,
so there is no way to "tell" nagios to use bash if that makes sense)?”
If you do, and since I still can’t initiate the script should I su - nagios
user anyway?
And responding to Edwin’s question, it is on local host.
Thanks.
Mikhail.

Ok, so it's working fine when you run it from the command line, but not for
nagios user, correct? (If it's a shell script, nagios will execute it using the
proper interpreter, so there is no way to "tell" nagios to use bash if that
makes sense)?
I usually su - nagios user, then try and run it from that user account - that's
usually where the problem is, it runs fine for root or whoever, but fails for
the nagios user for whatever reason...

Sorry for confusion - I was just trying different combinations.
But initially my command definition was following:
define command{
command_name dlg_notifications
command_line /usr/local/nagios/libexec/nagios-msg-broker.sh
}
I have "#!/bin/bash" in the top of my shell script, and shell script is set to
be executable.
perfserver-10:/usr/local/nagios/libexec$ ls -l nagios-msg-broker.sh
-rwxrwxrwx 1 nagios nagcmd 149 Mar 30 10:04 nagios-msg-broker.sh
Thanks.
Mikhail.

I'm slightly confused - Do you have "#!/bin/bash" in the top of your shell
script, and is it set to be executable by (at least) the nagios user? (Not
sure why you are calling bash then the script name as an arg, that is odd to
me, but maybe I'm missing something)?

Hello,
I have the following command:
define command{
command_name dlg_notifications
command_line /bin/bash /usr/local/nagios/libexec/nagios-msg-broker.sh
}
And the following service
define service{
use mypc
service_description
dlg_Alerts_notifications
check_command dlg_notifications
max_check_attempts 1
retain_status_information 0
retain_nonstatus_information 0
}
/bin/bash /usr/local/nagios/libexec/nagios-msg-broker.sh
runs fine manually.
Service defined above can’t run it though.
While googling around, I found out that apparently Nagios does not know that
script should be executed by /bin/bash
How would I let Nagios know about /bin/bash
Thanks.
Mikhail.
