Re: [Perfparse-users] Perparse Method 4 (pipe)

[Tim W. <tim...@gm...>]

You can update the perl script that nagios uses to write the data to
the pipe (in your config this is
/usr/local/nagios/bin/perfparse_nagios_command.pl), so that it will
not write anything if the pipe does not exist. That way, you prohibit
the script from creating it as a regular file if it doesn't exist yet.
I believe this should do the trick.

Tim.

#! /usr/bin/perl -w

use strict;
my $file = shift @ARGV;
exit(0) unless (-p $file);
open FH, ">$file" or die "'$file' could not be opened for appending\n";
print FH join("\t", @ARGV);
print FH "\n";
close FH;
