OC12 Monitoring

[jeremy27]

Hello everyone,

I have a problem where I am monitoring a POS interface on our edge router and it shows as 0megs when it goes over 115 megs on the interface, I am using snmp2 and need help to why it will not show the bandwidth useage over 115

Thanks,

Jeremy

check your data source to make sure the limit isn't set at 115 for the values it will accept.
it might be set at 100, u might need to increase that, or if ur using a data template, don't set a maximum so it will show up in the data source as U

I tried the fix by upping the limit form 100000000 to 611000000 which is the max bandwidth on an oc12 (roughly) and it still did not registered. Somone mentioned something about 64bit counters but I could not get it to work either.

You can always increase the interval that cacti/cmd.php runs at for a temporary fix. RRDTool does a good job of interpolating data when fed at various intervals. Of course using 64-bit counters is definitely the best solution to this problem.

Everyone,

I have adjusted the counters to 64 bit, Now my graph says NaN, I am at a loss here since I really need to monitor this connection and I can' seem to get it to work.

For 64-bit counters to work, your device must be set to SNMPv2.

I readded the host and changed to snmp v2 and 64 bit counters it won't read any bandwidth coming though the GSR POC interface

Can you run the following snmpwalk command against your GSR device? Make sure to substitute the hostname and community name. This will tell you if your device supports 64-bit counters and that it is working correctly.

Code: Select all

snmpwalk -v2c -c public 172.16.100.1 ifHCInOctets

Which interfaces on this device are you trying to graph traffic for? According to this output, there are only two interfaces that are actually generating traffic. Are you using cmd.php or cactid? Either way, could you run the poller manually from the command line and see when the about looks like with respect to this device?
