[Perfparse-users] Perparse Method 4 (pipe)

[Tong Y. <To...@in...>]

I have read through the documentation and groups and got it working, but
I need to manually run ./perfparsed before the service-perfdata.log file
is created by nagios.  Is this by design?
=20
Should I create some script to run perfparsed before nagios starts.  Or
did I miss something that is suppose to run perfparsed by itself?
Thanks!

If you are running nagios-1.2, yes, this is by design.
Perfparsed reads from a pipe, and creates it if necessary. If you run nag=
ios-1.2 before,
it will write to whatever the file is, and if it does not exist, write a =
new file.
If the design was to run perfparsed after nagios, you would loose the dat=
a written in
that file, or have perfparsed block because of that regular file.

[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;
