Re: Citrix plugin

Dear Jens,

(Konqueror looks pretty sharp.)

Please would you let me know if you are using the embedded Perl Netsaint
[1]

If you are, I think that may be the root of the problem [2].

Really, this is a problem that should be fixed in Netsaint/Nagios: the
plugin argument handling in the driver for the embedded Perl interpreter
needs revision. (this is the program named p1.pl)

There is only one work around that I am aware of: wrap the plugin in a
C wrapper so that Netsaint doesn't see it as a Perl program [3]

Yours sincerely.

that echos its arguments.

embedded perl plugin return code and output was: 0 & '$ARGV[1]: 'In
$ARGV[2]: the $ARGV[3]: beginning $ARGV[4]: was $ARGV[5]: the
$ARGV[6]: word' $ARGV[7]: 'and $ARGV[8]: the $ARGV[9]: word' '

Enter file name: ap5 ''In the beginning'' ''was the word''             
embedded perl plugin return code and output was: 0 & '$ARGV[1]: ''In

3 C wrapper for Perl plugins that won't run with an embedded Perl
interpreter.

It's a good idea to rename your Perl program with a .pl suffix so you
can use the unsuffixed name for the executable name.


int
main(int argc, char *argv) {
  execv("/usr/local/netsaint/libexec/<your_perl_program>.pl", argv) ;
}

gcc -o <check_name> wrapper.c
