Greetings,
I am running 2.2.3. I am trying to capture interface utilization numbers. While I have no trouble logging on ifInOctets MIB, I am just getting a cumulative or increasing value. What I am trying to log is the utilization for a point in time, i.e., Mbps. Am I missing an easy template or method for doing so?
I currently am logging ifIN and ifOut Octets. The key is named CPE_eth0_IN ( I could not used the named MIB because the device does not support, had to use OID and name the key). So I was hoping to create an calculated expression that would take the most recent value, minus the next recent, and divide by 60. Logic would be to sample every 60 seconds, so the difference between the 2 values divided by 60 would give me per second value. My most recent attempt at the expression has been "last(CPE_eth0_IN)-last(#2)(CPE_eth0_IN)/60".
Please help if I am missing an easier way, or if you can offer suggestions on how to properly write the expression for the calculated item.
Thanks in advance!
