perfdata

[Anthony Montibello]

hi all,

in responce to Mark's comment of:
Also, it's not going to hurt, but you don't really need to say
"/usr/bin/perl /usr/share/nagios/nagiosgraph/insert.pl" as long as
insert.pl is executable and has "#!/usr/bin/perl" as the first line.

Acctually it may hurt.  There was a thread in the Nagiosplugin Help mailing
list this week that discussed this.

if the insert.pl is called without the /usr/bin/perl and Embedded Perl is
enabled then the Embedded perl will run the script despite the #! on the
first line of the script. This may cause the script to not work.  likewise
with the /usr/bin/perl in the command then it will always use the External
Perl.

If Embedded Perl was not compiled into the Nagios install, then what you say
would be completly true.
