[Perfparse-users] Nagios 1.X and PIPE

[Michael G. <mic...@pa...>]

Hello,

I have complied nagios 1.2 with --with-default-perfdata --enable-
embedded-perl --with-perlcache

I then complied perfparse 0.105.6

I want nagios to feed perfparse via a PIPE since that seemed like the
best option.

In my nagios.cfg file I have the following:
cfg_file=/home/mgale/downloads/network-
monitor/netmonitorbase/etc/nagios_perfparse.cfg
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata

In perfparse I have:
Service_Log = "|/home/mgale/downloads/network-
monitor/netmonitorbase/var/serviceperf.log"

And I setup the DB area:
DB_User =                    "perfpase_user"
DB_Name =                    "perfpasedb"
DB_Pass =                    "perfuser"
DB_Host =                    "127.0.0.1"

In my resource.cfg file I provided $USER2$ with the path if the
perfparse install.

I added this to my nagios_perfparse.cfg file:
define command{
        command_name    process-service-perfdata
        command_line    $USER2$/bin/perfparse_nagios_command.pl $USER2
$/var/serviceperf.log "$TIMET$" "$HOSTNAME$" "$SERVICEDESC$" "$OUTPUT$"
"$SERVICESTATE$" "$PERFDATA$"
        }

Now in my .../path/var directory where all the nagios logs and perfparse
logs are setup there is a serviceperf.log what is incrementing with all
the data:

But nothing is being added to the database ... and there are no reports.
Now I have only started the Nagios process. I do not have to start any
perfparse process because it is feed with a PIPE ?

Have been going through the online documentation for a few hours trying
to figure this out ... 

Thanks.

Michael.

you should start perfparsed daemon in order to process data written to 
the pipe and to store that into the DB

Another solution should be this posted in list by Tim:
*******************begin cut and paste*******************
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;
*******************end cut and paste*******************

A note: use perfparse_nagios_pipe_command.pl instead of
perfparse_nagios_command.pl in your perfparse_nagios_command.pl
definition. Obviously modify perfparse_nagios_pipe_command.pl perl 
script  ;)

Re: [Perfparse-users] Nagios 1.X and PIPE

[Michael G. <mic...@pa...>]

Hello,

	I believe I have my nagios working correctly with perfparse now ... no
thanks to the documentation. 

I followed all the steps in the how to for using the PIPE method. Now
the data would just fill up in the serviceperf.log and never get into
the database.

It turns out that you have to run the perfparsed binary to start / open
the PIPE. 

Now this does not simple work by executing the binary .. you will need
to pass it parameters for how the data should be stored.

The log files should show "No module was loaded. Check the
Storage_Module_Load config option" .. so I run the binary with:

./bin/perfparsed --storage_modules_load mysql &

This started the perfparsed app and created the PIPE. Now data is being
sent into the database ... so it seems to be working.

Michael.
