System alerts (classic)

System alerts inform you of special circumstances during system operation. There are four types of system alerts. For each type of system alert, find below its associated warning messages along with the description of the situation that is at the origin of the alert.

The following recipients receive system alerts via email:

• For license alerts, the contacts specified in the Nexthink contract

• For all other types of system alerts, the admin account

License alerts

The Central License Manager (CLM) sends email notifications related to the status of the product license.

The recipients of the notification are those specified in the contract with Nexthink:

• To: Customer contact

• Cc: Partner contact

• Cc: Nexthink sales contact

The following types of notifications exist:

Activation key

When a new license is created on the Central License Manager, the system sends an activation key. Users need this activation key to activate the product.

Modification of the license

When there is a modification made to a license in Central License Management, the system sends an automatic notification.

For online licenses, the system automatically applies the modification after a maximum of 6 hours. If necessary, you can force the refresh of the license by going to the web interface, opening the view License Management and clicking the refresh button in the upper-right corner of the page.

For offline licenses, the system will send the modified license file attached to the notification. You must upload this file using the web interface, in the view License Management so that the system can apply the changes.

The system only sends notifications if the license is active and not revoked.

License alerts

The Nexthink solution also sends another type of license notification.
