check_cisco_license_date

Project Notes

Nagios check in python to fetch by snmpwalk Cisco OID related to license expiration and trigger alarm based on it.
OID is 1.3.6.1.4.1.9.9.543.1.2.3.1.16 which is clmgmtLicenseEndDate.
It is setup for Cisco CSR 1000V which can use per year license (eg. in AWS).
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.

Run as follow :
/usr/local/nagios/libexec/check_cisco_license_date -H <IP> -c <number of days> -w <number of days> --snmp "-v 3 -a hash -A pass -l authPriv -u mysnmpuser -x cypher -X pass -r 5 -t 30"
