Administering
Learn how to administer settings in HCL Launch elements and communication between the elements.
- High availability and failover
  You can configure clustered HCL Launch servers, and agents for high availability. You can also configure agents and agent relays for failover.
- Setting up high-availability clusters
  To configure a high-availability cluster, you store shared files on network storage. Then, you configure multiple servers, set each server to access the same files and database, and configure a load balancer to distribute the traffic between the servers.
- Adding cold standby servers
  You can add cold standby servers to serve as a backup server or for disaster recovery. You must start the secondary server or servers when the active server fails, and network traffic is routed to the secondary servers.
- Backup and recover
  You can back up and recover the contents of your HCL Launch installation.
- Server settings and configuration
  After you install HCL Launch, you can modify the server configuration and configure more options.
- Setting user preferences
  Each user can specify display options for the server, including the language for the server and how the server shows times and dates.
- Agents and agent relay configuration
  After you install an agent for HCL Launch, you can modify its configuration or create an agent relay to facilitate communication to remote relays.
- License management
  HCL Launch provides a 60-day license-free evaluation period. To use all product features after the evaluation period, you must have a license.
  - HCL license scenarios
    After the evaluation period, you must acquire agent licenses before you can use all product features. These agent licenses can be used in few of the scenarios mentioned below.
  - Tracking agent usage
    You can track daily agent usage. Agent usage can provide a rough estimate of agent license use.
  - Managing licenses
    You can download the software for installation and manage the licenses that are associated with your order.
- Setting up the wizard for new users
  HCL Launch includes a wizard to help users become familiar with the procedures and steps in creating a deployment. Some configuration is required before the wizard can be used.
- Customizing the table views
  Customize a table view in the HCL Launch application by hiding or showing, and reordering of the table columns.
- Managing data

Tracking agent usage

You can track daily agent usage. Agent usage can provide a rough estimate of agent license use.

HCL Launch records the number of agents online and the maximum number of agents deploying at a time. Both measurements are referred to as the agent high-water mark. The records are updated very 10 minutes and are aggregated at the end of the day.

Although the agent usage records do not correspond precisely to agent license use, they can provide useful estimates of agent license use. These estimates can be especially useful for installations of HCL Launch on z/Linux™. If you are using z/Linux, review your agent high-water totals quarterly. If you discover that you significantly or routinely exceed your licenses, contact your sales representative to ensure that your installation remains compliant.

The agent usage records can be accessed at the following REST API endpoint:

https://{hostname}:{port}/cli/agentCLI/usage

The REST endpoint returns a JSON object with both the highest number of agents online for the day, and the maximum number of agents deploying at a time. A typical JSON object returned by the command is shown in the following example: {"onlineAgents":5,"agentsrunningDeployments":4}.

Both measurements are referred to as the agent high-water mark. For information about the CLI command, see getHighWatermarks. For information about the REST API method, see Return high watermarks for agent usage.
