Monitoring LAS activation blob expiry

You can use the SVM GUI and CLI to track your LAS activation blob expiry and avoid unexpected license interruptions.
SVM GUI:
Navigate to SVM GUI > Configuration > System > Licenses > LAS Offline Activation > ADC Licenses, and monitor your Upcoming Renewal.

SVM CLI:
You can use the show license command and refer to the value of the Expiry Days parameter.
Sample:
show license 

                       Platform: 9120 
                        Cluster: false 
              Maximum Instances: 4 
            Available Instances: 4 
      Maximum Throughput (Mbps): 20000 
    Available Throughput (Mbps): 20000 
                isPooledLicense: false 
                    Expiry Days: 208 
                   isLASLicense: false 
              isLASFixedLicense: true

SNMP-based notification

The SNMP trap or alarm is named LicenseExpiry for upcoming expiry and LicenseExpired for already expired.The SNMP trap LicenseExpiry is triggered by default by the NetScaler SDX instance when the LAS activation blob expiry is upcoming in less than 30 days. This trap is generated every 24 hours, starting 30 days before LAS activation blob expiry, and continues until the blob is expired.
You must set an SNMP trap destination for the SDX/SVM. Once done, you will receive these SNMP traps.
Sample:
[EventNotification[#1]] Inside: send_ns_snmp_trap_LicenseExpiry

You can view the generated events by navigating to System > Events. The message shown is: "LAS Activation blob to expire within d days".
