Avoid orphaning agents and appliances

If the agent is outdated, you cannot reclaim the agent, and must reinstall the agent. Refer to the following documentation:

• Uninstall the Alert Logic Agent for Linux and or Uninstall the Alert Logic Agent for Windows
• Install the Alert Logic Agent for Linux and or Install the Alert Logic Agent for Windows

If you deleted the deployment, you must create a new deployment with proper credentials for that AWS account or Azure subscription. Refer to the documentation below:

• Azure Deployments
• AWS Deployments

You must review and fix your credentials. Refer to the documentation below:

• AWS IAM role update
• Azure RBAC role update

You must create a network CIDR in one of the Data Center deployments by following the instructions Add assets section.

To create a new Data Center deployment, refer to Data Center Deployment Configuration (Professional Subscription).

When installing Alert Logic Agents to new hosts in the environment, you must use the associated network Unique Registration Key. If you have migrated to MDR from the older Cloud Defender platform, this replaces the legacy claim key that you used previously. You can find the correct claim key in the Alert Logic console by following the steps below:

1. Click the menu icon () to see the navigation menu.
2. Click Configuration, and then click Deployments.
3. Click on the deployment you wish to claim the orphan agents to.
4. Click on Installation Instructions.
5. One or more Unique Registration Keys will be presented. You need to update the legacy claim key with the appropriate new Unique Registration Key.

To update to a new Unique Registration Key

For Scripted methods in Linux, update the script with your Unique Registration Key as instructed in step 5 of the Install the agent documentation.

For scripted methods in Windows, update the value “prov_key” with your Unique Registration Key.

For base image, uninstall and reinstall the agent using the new claim key using your Unique Registration Key.

• Uninstall the Alert Logic Agent for Linux or Uninstall the Alert Logic Agent for Windows
• Install the Alert Logic Agent for Linux or Install the Alert Logic Agent for Windows

When a network is not found, you must create a CIDR in your Data Center deployment.

If you already have a Data Center deployment you can add a network CIDR to that network by following the instructions Add assets section.

To create a new Data Center deployment, refer to Data Center Deployment Configuration (Professional Subscription).

When there are multiple CIDR intersections, an Alert Logic team member will contact you about the issue and will work internally to resolve it.
