Nagios Support Forum

To the contrary, It is the absence of bandwidth with high ping times that confounds me. We have ample bandwidth at all branches (according to Nagios graphs) but still experience severe slowdowns and high pings at times throughout the day. Without access to the ATT routers in between I am certainly f...

No Errors in MRTG

[rot@localhost ~]# ls -al /etc/mrtg/conf.d/ | wc -l
36
[root@localhost ~]# ls -al /var/lib/mrtg/ | wc -l
760

I have asked myself the question and I determined that it appears to be either MRTG or a sampling issue with snmp on ADTRAN routers. Are you aware of any issue with ADTRAN router snmp or MRTG accuracy? If you can rule those two out then I'll go back to ATT ask them for their graphs again. Something ...

CentOS 2014R2.6 VM The issue: MRTG shows very low bandwidth on 192.168.xx.1 Adtran routers (Under 1MB) but intermittently we get very high (500 -1000ms) ping times with severe slow downs at the branch endpoints. We have Netvanta 1238/1224 PoE and Adtran 3448 Routers with very basic configurations. W...
