[Nagiosplug-help] NRPE returns correct data, while Nagios shows "No Output"

[Erik Cummings]

James,

                It doesn't sound the same - but the last time I ran into
this it was because the SUDO session for all users required TTY.  The
NRPE session doesn't have a TTY.  But for us this caused the REMOTE NRPE
call to fail.  It sounds like you are able to do the remote call
properly...so probably not the same thing.

"No Output"

 

Hi all, 

I've written some custom plugins that monitor some software around a
cluster.  I can run them on the individual cluster nodes with "sudo -u
/usr/local/nagios/libexec/plugin.pl" and i get a single line printed to
stdout and the correct return value. 

All looks good?

So then I run the nrpe client on the nagios server to retrieve the
values returned from the plugin like so:
"sudo -u nagios /usr/local/nagios/libexec/check_nrpe -H cluster_node -t
30 -c check_remote_plugin" 

Which also prints the expected string and return value ( which is
something like "plugin:OK blahh text \n")
and returns the correct value ( 0 in this OK state).

So far so good?

But when I go to the nagios servers web page (status grid) I get WARNING
"(No output!)" 

I've been scratching my head about this for a while now, can anyone over
a solution??
