The Chariot® MQTT Server Web UI allows for uploading, activating, and deactivating valid Chariot Licenses.
If you have deployed Chariot through AWS Marketplace or Azure Marketplace, then no additional steps are required - your license is already installed and activated.
This tutorial will cover the process for both online and offline activations and deactivations:
Prerequisites
- Request a valid Chariot License from Cirrus Link Support.
- Alternatively purchase a license through the UI.
- Follow the Chariot® MQTT Server Installation instructions to download and install Chariot MQTT Server instance.
License Activation
The Online Activation feature allows a Chariot License to be automatically activated on a Chariot MQTT Server instance that is connected to the internet. The Chariot MQTT Server will remotely connect and activate a Chariot License if it is valid and has an activation available.
Log into the Chariot MQTT Server Web UI and from the left hand menu bar select License as shown below:
Follow the wizard selecting first the license activation method type
- Online - Requires an external internet connection and Chariot license key
- Offline - No external internet, will require email communication with Cirrus Link providing generated codes to gain the appropriate access
- Floating - A self hosted license server that you provide a URL to, this will server available licenses to systems as needed
Online
Select "Online" activation method
Provide the text file containing the Chariot License Key. This can either be done by dragging and dropping, typing, or clicking the upload button and selecting a file.
Confirm you are finished with the wizard
Offline
Select the "Offline" method
Next select generate usage request
Enter a valid license key and click next a popup with your offline activation code will appear. This will have to be provided to Cirrus Link Support via email so that a usage license can be properly generated.
Once you receive an email from Cirrus Link Support containing your Usage License follow the wizard to finish your offline activation.
Only do this ONCE as each new Activation Request will invalidate the previous one.
Floating License Server
Select "Floating" activation method in the wizard
Provide a valid floating license server URL and select the appropriate Chariot feature set
Verify entry and click finish when ready to complete license activation flow
Successful Activation
A successful activation will lead you to the license status. This will show you the state of your license, activated features and other details associated with licensing
Online/Floating License Deactivation
In order to deactivate the license online, log into the Chariot MQTT Server Web UI and from the left hand menu bar select License as shown below.
Select "Deactivate" for the license to be remotely deactivated so that it can be potentially activated on another Chariot MQTT Server instance.
If the server is terminated, deleted, or destroyed without deactivating the active Chariot License, that license will permanently lose one of its total number of activations
Once deactivation is successfully complete you will be returned back to the license activation wizard
Offline License Deactivation
In order to deactivate the license offline, log into the Chariot MQTT Server Web UI and from the left hand menu bar select License. Select deactivation:
This will provide a Deactivation Request code that should be provided to Cirrus Link Support along with the License ID in order to free up the previous activation for use with another Chariot MQTT Server instance.
Reactivation
If at any point your online / floating license has a feature change, expiration date change, or any other information that requires an update. Click the reactivate button to update your license information remotely. 
This will not work with offline activated licenses. You will need to contact Cirrus Link Support for any changes.
