Own Custom Graphs

Posted: Mon Dec 21, 2015 3:15 am
by gmikhailov
Hello All.
I would like to make my own custom graph based on nagios bandwidth.
What I did:
1. I created new command "testddos" - a little modified script "check_iftraffic64.pl" -
2. I did php file /usr/local/nagios/share/pnp/templates/testddos.php

Code: Select all

<?php
$opt[1] = " --vertical-label \"Traffic\" -b 1024 --title \"Interface Traffic for $hostname / $servicedesc\" ";
$def[1] .= "DEF:var1=$rrdfile:$DS[3]:AVERAGE " ;
$def[1] .= "DEF:var2=$rrdfile:$DS[4]:AVERAGE " ;
$def[1] .= "CDEF:real1=var1,1,* " ;
$def[1] .= "CDEF:real2=var2,1,* " ;
$def[1] .= "LINE1:real1#003300:\"in  \" " ;
$def[1] .= "GPRINT:real1:LAST:\"%7.2lf %Sb/s last\" " ;
$def[1] .= "GPRINT:real1:AVERAGE:\"%7.2lf %Sb/s avg\" " ;
$def[1] .= "GPRINT:real1:MAX:\"%7.2lf %Sb/s max\\n\" " ;
$def[1] .= "LINE1:real2#00ff00:\"out  \" " ;
$def[1] .= "GPRINT:real2:LAST:\"%7.2lf %Sb/s last\" " ;
$def[1] .= "GPRINT:real2:AVERAGE:\"%7.2lf %Sb/s avg\" " ;
$def[1] .= "GPRINT:real2:MAX:\"%7.2lf %Sb/s max\" " ;
?>
I want to make outgoing and incoming graph on one DS.

3. I checked rrd

Code: Select all

[root@nagiosz1s1 templates]# rrdtool fetch /usr/local/nagios/share/perfdata/Physical_Channel_MTC_DC_-_DefaultGateway/DDoS_test_check.rrd MAX -r 900 -s -40m (the service name is DDoS_test_check)

It looks OK.

4. I checked xml

Code: Select all

It looks fine too.

But graph doesn`t draw (screenshot in attachment).

Please write, where I made mistake.
Thank You.

Can you also post a screenshot of the 'Advanced' tab for us to take a look at as well?

Hi, rkennedy
The screenshot of the 'Advanced' tab in attachment.
I would like to combine 2 graphs in one - inBandwidth and outBandwidth. ([3] [4] in php file).

From my experience, this can be frustrating to diagnose.

The problem is most likely in your template file.

I would do two things:
1)

Code: Select all

tail -f /var/log/httpd/error_log
This should report any coding errors.

2)
Make the php template as basic as possible. Start off with just the heading line and comment everything else out.
Once doing that, does it work?
If yes, then uncomment the next line and repeat.

1. There are no any mistakes in log file.
2. Of course the mistake in template. I think, that my template is very simple and it must work.

I understand, but 1 line is more simple than 13. It just takes one mistake to make it break.

OK, I`ll try to check template by your recommendation.

Thanx to all for help.
