How to check Device OID for Bandwidth Utilization


#1

So we are monitoring a bunch of Cambium APs and we are having to write scripts to create Weekly, Monthly Bandwidth Reports. I’ve seen that a report to email function has been mentioned as a feature request a few times. So this is out work around. Currently legacy Cambium APs are looking comparible to the reports that we were pulling from Zenoss. However the 450APs we would like to setup in Slot Utilization instead. My question is how do we check what OIDs the devices are using?


#2

Looking at the Cambium device page, you can open “capture” form the gear on the right side. This allows you to see the results of the discovery, poller, snmp and Alerts … is this what you are looking for?


#3

Is there output in this debug on the specific OID used to create the utilization graphs?


#4

Looking at the Libre Graphs VS SNMP walks at the same time that the polling’s occurring it’s clear that the DL utilization graphs are based on the 1 Minute utilization rather than 5 and 15 Minute. Is there a way to change the OID this graph is polling to the 5 Minute utilization. And if not how can I add a new graph with a Custom OID using the 5Min utilization.


#5

Hows that gonna work poller runs at 1 min or 5min?


#6

We are not wanting to change the poller we want to change the OID on the framing utilization that the AP stores locally. We will poll the different OID to get the 5 minute average (which the AP keeps on itself) from the AP when we poll it. The polling interval will not matter


#7

How’s it gonna pull the data?


#8

Via the SNMP oid for the 5min downlink utilization that the manufacturer provides via their MIB


#9

???. So is this not possible to use the 5 minute interval instead of the 1 minute that it is currently using.


#10

I guess you could change over to one minute polling.

check the docs for one minute polling.
