[Nagiosplug-help] check_squid

[Ralph.Grothe at itdz-berlin.de]

Hi Ryan,

yes, I am afraid your plugin is a completely different one than
the one that I use,
though both of them are implemented in Perl.

I can't even compile your plugin (where did you get it from?)
because I lack a prerequisite module libplugins.pm

$ perl -cw check_squid1.pl 
Can't locate libplugins.pm in @INC (@INC contains: .

If your system meets the prerequisite libplugins.pm (and possibly
others)
then there should be nothing against using this plugin instead.

I don't feel that inclined to look at the implementation of your
check_squid.
So I gave it only a very superficial peek for the help message.
Unfortunately I couldn't find it (might be in the missing
libplugins.pm though?).
I only noticed that although GetOptions takes an $opt_h
it never seems to referred to later on.
Maybe this is still work in progress and the plugin author hasn't
found time yet
to add the help screen?


Excerpt from your plugin:

     64 
     65 my ($opt_V,$opt_h,$opt_m);
     66 
     67 GetOptions (
     68         "V"             => \$opt_V,     "version"
=> \$opt_V,
     69         "h|?"   => \$opt_h,     "help"
=> \$opt_h,
     70         "man"   => \$opt_m,
     71         "d=i"   => \$DEBUG,     "debug=i"
=> \$DEBUG,
     72         "w=i"   => \$opt_w,     "warning=i"
=> \$opt_w,
     73         "c=i"   => \$opt_c,     "critical=i"    =>
\$opt_c,
     74         "H=s"   => \$opt_H, "hostname=s"        =>
\$opt_H,
     75         "p=s"   => \$opt_p, "password=s"        =>
\$opt_p,
     76         "P=i"   => \$opt_P, "port=i"            =>
\$opt_P,
     77 );



$ grep -n \$opt_h check_squid1.pl 
65:my ($opt_V,$opt_h,$opt_m);
69:     "h|?"   => \$opt_h,     "help"                  =>
\$opt_h,


Good luck

Ralph
