Final stage of getting MRTG working with Nagios v2

[AJay]

Your mrtg is probably not working correctly, check you mrtg.cfg and /var/spool/mail/root to see what's going on with mrtg.

 Subject:  [Nagios-users] Final stage of getting MRTG working with Nagios v2

  
 Hello,
  
 I have been fluffing around with Nagios for a couple of weeks, and have nearly finally nailed it.
  
 I just have one thing to go.
  
 I am trying to get MRTG to work with Nagios.
  
 I have got MRGT working locally on my machine , and can see it working by going to these 2 sites  (locally)  in a browser:
  
 file:///usr/local/mrtg-2/share/mrtg2/icons/index.html and 
  
 file:///usr/local/mrtg-2/share/mrtg2/icons/localhost_2.html
  
 I followed the tutorial below to set up my router with Nagios:
  
 http://www.thegeekstuff.com/2008/11/how-to-monitor-network-switch-and-ports-using-nagios/
  
 however I am yet to get MRTG working with Nagios:
  
 PING OK 11-14-2009 13:13:56 21d 16h 10m 13s 1/3 PING OK - Packet loss = 0%, RTA = 1.38 ms  
 Port 1 Bandwidth Usage UNKNOWN 11-14-2009 13:09:49 21d 16h 8m 43s 3/3 check_mrtgtraf: Unable to open MRTG log file  
 Port 1 Link Status OK 11-14-2009 13:11:29 12d 22h 37m 5s 1/3 SNMP OK - up(1)  
 Uptime OK 11-14-2009 13:10:29 12d 22h 27m 57s 1/3 SNMP OK - Timeticks: (152738042) 17 days, 16:16:20.42
  
 My switch.cfg currently has the following:
  
 # Monitor bandwidth via MRTG logs
 define service{
use     generic-service ; Inherit values from a template
host_name    Billion
service_description   Port 1 Bandwidth Usage
check_command    check_local_mrtgtraf!/usr/local/mrtg-2/share/mrtg2/icons/localhost2.log!AVG!1000000,1000000!5000000,5000000!10
 }
  
 
My localhost2.log is at the location above: /usr/local/mrtg-2/share/mrtg2/icons/localhost2.log ,however I still must have something wrong for it to not work.
  
 When I run: /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg , it says: "Things look okay - No serious problems were detected during the pre-flight check"
  
 When I run: /usr/local/mrtg-2/bin/mrtg /home/mrtg/cfg/mrtg.cfg , it says: 
  
 -----------------------------------------------------------------------
ERROR: Mrtg will most likely not work properly when the environment
       variable LANG is set to UTF-8. Please run mrtg in an environment
       where this is not the case. Try the following command to start:
  
        env LANG=C /usr/local/mrtg-2/bin/mrtg /home/mrtg/cfg/mrtg.cfg 
----------------------------------------------------------------------- 
  
 When I run: env LANG=C /usr/local/mrtg-2/bin/mrtg /home/mrtg/cfg/mrtg.cfg  , there are no errors. 
 
 Does anyone know what I am still doing wrong
  
 Thanks for any help,
  
 Kind regards,
 Anthony
