+title: License Manager
+url: /instance-administration/license-manager/
+---
+
+_The License Manager is accessible from **[Administration > Configuration> License Manager](/#sonarqube-admin#/admin/extension/license/app)** as part of [Developer Edition](https://redirect.sonarsource.com/editions/developer.html) and [above](https://www.sonarsource.com/plans-and-pricing/)._
+
+## License Manager
+
+The License Manager enables retrieval of your Server ID (required for obtaining a License Key) and configuration of your SonarSource-provided License key.
+
+### Retrieving Server ID
+The Server ID is always available on the License Manager page, as well as in the System section of the System Info .
+
+Note that if the database connection string is updated, the server ID will be re-generated and a new license will be needed. When it is generated, the Server ID is unique. The same Server ID will never be generated twice, even on the same SonarQube instance.
+
+### Setting a License
+Using the "Set new license" button, you can set a new License to enable or disable features in SonarQube, or simply to update your license.
+
+### LOCs Consumption
+The gauge indicates the quantity of LOCs you are currently scanning and allows you to check if you are near the limit and if you need to purchase additional LOCs.
+
+### Global admin notifications
+The License Manager comes with two notification mechanisms built-in (notifications are sent to Global Admins):
+
+- when the license is about to expire–sent two months before expiration, with a reminder one month before
+- when the configurable LOC threshold is exceeded–this threshold can be modified via the indicator present on the LOC gauge
+- the background job, that checks threshold and decide if a notification should be sent, runs at server startup, then every 24 hours
+- the background job does not check validity of smtp server settings and if the emails addresses are set up for global administrators, 
+therefore for notifications to be received, these settings needs to be correctly configured before the LOC threshold is reached or exceeded
+
+### Features Included section
+
+This sections of the License Manager page lists the commercial features that are enabled by the license currently set.
+
+## Support
+
+### Access to SonarSource Support
+If your License entitles you to SonarSource Support, A **Support** tab will appear at **[Administration > Support](/#sonarqube-admin#/admin/extension/license/support)** to guide you through interactions with SonarSource Support.
+
+This page also allows you to collect the Support Information File of your instance. Make sure to provide this file for any interaction with SonarSource Support.
