Nagios check in python review the number of APs associated to a Cisco Wlan Controller using snmp and trigger alarms if less than critical or warning threshold.
Nagios check in python to fetch by snmpwalk Cisco OID related to AP and trigger alarm based on it.
OID is 1.3.6.1.4.1.9.9.618.1.8.4.0 which is "Connected AP's".
It is tested on Cisco 5508 with 8.2.166.0. You do not need specific MIB.
I have tested only with snmp v3 (no reason to use snmp v1/2c) but it should work with same syntax from snmpwalk.

It is in fact just passing most of parameters "as is" to snmpwalk. I recommend to include some timeout and retry value like below. Adjust based on you need, check syntax from snmpwalk and use "" to define as a single string snmp argument.

Check if number of APs listed in critical is < than current on wlan controller, if not check if number of APs listed in warning .
Run as follow :
/usr/local/nagios/libexec/check_snmp_wlc_ap -H -c -w --snmp "-v 3 -a hash -A pass -l authPriv -u mysnmpuser -x cypher -X pass -r 5 -t 30"
