AP MiB values for MRTG

I have found some archived posts for monitoring the Aruba's using MRTG  - is there a list anywhere of MiB's for the AP's. Im especially interested in building up historical usage graphs for our AP's. Ideally Id like to know how many users we are seeing on each AP over a period of time for capacity planning.

I have seen MiB's for the 6000 controllers giving me how many users per controller, but nothing for how many users per AP?

 

Is there any good documentation around for this?

 

Thx

Re: AP MiB values for MRTG

With current versions of ArubaOS, all SNMP erlated topics are covered in the ArubaOS SNMP MIB Guide.

 

The MIB files themselves are the best reference.

 

In additon, the Aruba Instant units offer good SNMP MIB support as well.

 

Most of the AP-specific stats are indexed by radio, and or BSSID as well as AP. Since most of this data

is relevant to a radio, a channel, or an SSID, the numbers are not simply indexed by physical AP units.

 

To give just a start on what is possible:

 

Dealing strictly with an ArubaOS controller, I'd reference the wlsxWlanAccessPointInfoGroup, and investigate down the MIB tree:

.1.3.6.1.4.1.14823.2.2.1.5.2.1

 

wlanAPNumBootstraps

.1.3.6.1.4.1.14823.2.2.1.5.2.1.4.1.20

 

wlanAPRadioNumAssociatedClients (indexed by AP and radio)

.1.3.6.1.4.1.14823.2.2.1.5.2.1.5.1.7

 

wlanAPBssidNumAssociatedStations (indexed by AP and BSSID)

.1.3.6.1.4.1.14823.2.2.1.5.2.1.7.1.12

 

 

These MIBs are indexed per BSSID

 

wlanAPNumClients

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.2

 

wlanAPTxPkts

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.3

 

wlanAPRxPkts

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.5

 

wlanAPFrameRetryRate

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.10

 

wlanAPFrameRetryErrorRate

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.15

 

wlanAPFrameRetryErrorRate

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.16

 

wlanAPFrameRetryErrorRate

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.17

 

wlanAPFrameRetryErrorRate

.1.3.6.1.4.1.14823.2.2.1.5.3.1.1.1.27

 

etc...

 

wlsxWlanStatsGroup.wlsxWlanAccessPointStatsGroup.wlsxWlanAPRadioStatsTable (indexed by AP and RADIO)

.1.3.6.1.4.1.14823.2.2.1.5.3.1.9

 

It really depends on how we want to see the data, and how many graphs one wants to create in tools such as MRTG.

It goes without saying -  the advantage offered by Airwave is that most of this work has been simplified, and is readily available in various forms.

 

I hope this is helpful.
