Best practices for monitoring your LAS transitioned NetScaler environment
This document focuses on the best practices that you can follow to monitor your NetScaler environments that use LAS. This document applies to deployments that use LAS with NetScaler ADC form factors: VPX (excluding VPX on SDX), MPX, and BLX having the Fixed Capacity Subscription license type.

Prerequisites
-
Read the LAS for NetScaler page, including the FAQs for LAS with NetScaler ADC.
-
Read the License Activation Service and complete your LAS migration.
-
Ensure that you set up the relevant notifications, and monitor the NetScaler GUI and CLI regularly.
Note:
We intend to make continuous improvements to notifications and keep this documentation updated accordingly.
Monitoring LAS activation blob expiry
You can use the NetScaler ADC GUI and CLI to track your LAS activation blob expiry and avoid unexpected license interruptions.
NetScaler ADC GUI:
Navigate to ADC GUI > Configuration > System > Licenses > LAS Offline Activation > ADC Licenses, and monitor your Upcoming Renewal.
Monitor NetScaler ADC GUI
NetScaler ADC CLI:
You can use the
show ns laslicense command and refer to the value of the Renewalnextdate parameter.
Sample:
show ns laslicense
Status: ACTIVE
DaysToExpiration: 878
Renewalprev: 1777877347 Renewalnext: 1809414247
Renewalprevdate: Mon May 4 00:49:07 2026
Renewalnextdate: Tue May 4 01:04:07 2027

Notifications
Banner on NetScaler ADC GUI:
This banner on the NetScaler ADC GUI is triggered by the NetScaler instance when LAS activation blob expiry is upcoming in less than 30 days. It appears on the GUI every time a user logs in.
Banner on NetScaler ADC GUI
You can configure this setting to appear "x" days before expiry. The default is 30 days before expiry.
To configure this setting, navigate to ADC GUI > Configuration > System > Licenses > ADC Licenses > Notification Settings, and click the Pencil icon to edit the details.
Configure days before expiry
A similar banner is shown if the LAS activation blob has expired.

SNMP-based notification
SNMP trap for upcoming LAS activation blob expiry:
The SNMP trap is named
nsLicenseExpiry. This SNMP trap is triggered by a NetScaler 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 can configure your SNMP manager to recognize this SNMP alarm and set up notifications as needed.
Sample:
May 5 23:30:14 <local0.info> 10.102.201.33 05/06/2026:05:30:14 GMT 0-PPE-2 : default SNMP TRAP_SENT 0 0 : nsLicenseExpiry (nsPartitionName = default)
You can configure this SNMP alarm to be triggered from
x days before expiry. The default is 30 days before LAS activation blob expiry.
To configure this setting, navigate to ADC GUI > Configuration > System > Licenses > ADC Licenses > Notification Settings and click the Pencil icon to edit the details.
SNMP trap
SNMP for LAS activation blob already expired:
The SNMP trap is named
nsLicenseExpired. This SNMP trap is triggered by a NetScaler instance when the LAS activation blob has expired.
You can configure your SNMP manager to recognize this SNMP alarm and set up notifications as needed.
Sample:
May 12 01:03:48 <local0.info> 10.102.201.33 05/12/2026:07:03:48 GMT 0-PPE-2 : default SNMP TRAP_SENT 0 0 : nsLicenseExpired (nsPartitionName = default)
Syslog-based notification
Syslog for LAS activation blob upcoming expiry:
A syslog is triggered by a NetScaler 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 can set up your syslog manager to recognize this syslog and set up notifications as needed.
Sample:
May 5 23:30:14 <local0.crit> ns nsnetsvc[97782]: nscfe_licenseexp_timer_handler(): Some licenses are expiring in 19 days. Please ensure timely renewal and apply the license to ensure uninterrupted functioning
You can configure the syslog to be triggered from
x days before expiry. The default is 30 days before LAS activation blob expiry.
To configure this setting, navigate to ADC GUI > Configuration > System > Licenses > ADC Licenses > Notification Settings and click the Pencil icon to edit the details.
Syslog-based notification
Syslog for LAS activation blob already expired:
A syslog is triggered by a NetScaler instance when the LAS activation blob has reached an expired state (that is, 0 days to expiry). You can set up your syslog manager to recognize this syslog and set up notifications as needed.
Sample:
May 12 01:03:48 <local0.crit> ns nsnetsvc[94684]: nscfe_licenseexp_timer_handler(): License expired, system will be unlicensed now. Rebooting the system...
Monitoring license entitlement expiry (contract expiry)
NetScaler ADC GUI:
Navigate to ADC GUI > Configuration > System > Licenses > LAS Offline Activation > ADC Licenses and monitor your License Entitlement Expiry.

NetScaler ADC CLI:
You can use the
show ns laslicense command and refer to the value of the DaysToExpiration parameter.
Sample:
show ns laslicense
Status: ACTIVE
DaysToExpiration: 878
Renewalprev: 1777877347 Renewalnext: 1809414247
