RRDTool exits with errors -> ERROR: can't make a graph without contents

[Navdeep Sidhu]

Hi

 

I'm using Nagios 2.8 with RRD tool version 1.0.50 & PNP version 0.3

installed. Nagios is running on RHEL-4. I'm facing an issue in RRD Tool.
Recently I have configured this tool

for Cisco devices (under serviceextinfo.cfg file) so that memory & CPU

utilization should be available in graphs however I'm getting following

error when trying to view the graphs.

 

RRDTool exits with errors -> ERROR: can't make a graph without contents.

 

 

This tool is working fine with Intel platform servers & displaying the

graphs however not working in Cisco devices.

 

I'm pasting excerpt of my host configuration & serviceextinfo file to
provide clear picture. In fact, in Nagios web console, I'm able to see
Memory & CPU utilization of Cisco devices however unable to view the
graphs. I'm using check_snmp_mem.pl plugin to capture Memory utilization
of Cisco devices. Let me know if any other info required from me. 

 

 

Excerpts of host Configuration File

 

define command{

        command_name    process-service-perfdata

        command_line    /usr/bin/perl
/usr/local/nagios/libexec/process_perfdata.pl

        }

 

Excerpts of Serviceextinfo File

 

define serviceextinfo{

              host_name                            L3-Switch

              service_description               MEM

              action_url
/nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$

              }

 

I would really appreciate your help in this regard.

 

Regards

Navdeep
