Subject: Re: [Nagios-users] Nagios ignoring Perl Shebang -
Was: Notification script problems.. How do I debug
You've probably got a Nagios with embedded Perl running. There's a
section in the manual with some hints how to write your Perl
scripts in
that case.
Arno
I don't think so.
I haven't been following this thread so I don't have too much helpful to
say but embedded Perl doesn't care about the shebang.
If the plugin text contains the string '/bin/perl' - usually in the
shebang line,
then the plugin is assumed to be Perl and is compiled by the Perl
compiler (called
by eval { }) once, and thereafter the in core op-codes executed without
recompilation.
Yes, but I *think* I recall something about special requirements for
Perl plugins that are interpreted by he embedded Perl engine. The manual
section docs/embeddedperl.html lists some restrictions and things to
consider. Anyway, since I never used ePN,I have no hands-on experience
if any "normal" Perl program needs chenges.
In any case, all my plugins and all the standard plugins have a standard
shebang line
that works fine with embedded Perl.
The usual way to deal with _any_ misbehaving program that Nagios runs -
plugins,
event handlers, the whole shebang - is to wrap the offender in a
reliable script that
captures the argv it was called with, invokes the program with those
args and then
logs args and stdout, stderr to somewhere convenient.
(I wish that were more common knowledge)
I know that this matter of wrappers has been discussed on this list
before
(my name and Andreas Ericsson).
Indeed, and those are valuable hints.
Arno
Yours sincerely.
