Hi Slansing,
Below is the output
Code: Select all
[root@nagios155 ~]# ll /var/lib/mrtg/172.17.241.9_14.rrd
ls: /var/lib/mrtg/172.17.241.9_14.rrd: No such file or directory
Can you please also help me with the SNMP error that i am getting for other Nodes as seen in screenshot

Do you have snmp enabled on those devices? It would seem that they are not responding to snmp queries. You can test with:
As for your rrd issue, if mrtg is not able to access snmp on the remote device, it cannot create an rrd, and therefore check_rrdtraff(the command used to display router info) will not work properly. So hopefully this all comes down to simply getting snmp working on those remote devices.

Hi
SNMP is been enabled on the Devices, and we are getting this error only for some port on the switches,
Below is the output of NMAP
Code: Select all
[root@nagios155 ~]# nmap -sU -p 161 172.16.201.152
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-06-04 14:20 IST
Interesting ports on 172.16.201.152:
PORT STATE SERVICE
161/udp open|filtered snmp

Have these ports in particular been removed and readded or reconfigured from nagios configurations and mrtg? Alternatively have they been continually running and the rrd removed at some point?
