I'm advancing monitoring through SNMP. Our customer wishes to have some more parameters which are:
* airtime utilization which is presented in Flexmaster. Please provide the method how to calculate it from SNMP values (or better yet provide the OID).
* ratio of 2.4/5GHz customers. This I can calculate by myself, but what I miss is the OID including the number of current users in a WLAN (not on AP!) using 2.4 and 5GHz radio type.
We would like to retreive (or calculate) the airtime utilization through SNMP as well. In the webinterface you calculate this percentage by deviding airtime-total by rf-samples. How to calulate this number from OID-retreiveble values?
I am also curious to know if an OID for airtime utilization exists.
We currently use the command "get airtime wifiX" (where X=0 for 2.4GHz and X=1 for 5GHz) per AP. This command gives raw counters for Total, Busy (interference/PHY errors), Rx and Tx for the moment you issue the command.
For example, on an APs you can have this:
