Whilst using some SNMP tools such as PRTG and Solar Winds, I've found the following OIDs to be useful for pulling certain info off the controllers.  I know I could trawl the MIB files, but has anyone else got any useful OIDs that they use? Total Number of Clients Associated to  controller 1.3.6.1.4.1.388.14.3.2.1.12.1.0 Number of Radios (not APs) seen by the controller 1.3.6.1.4.1.388.14.3.2.1.11.2.0 Number of clients associated to radio index "X" 1.3.6.1.4.1.388.14.3.3.1.2.11.1.18.X See the attached for an example of PRTG plotting the number of clients over 2 hours and 4 days.
