Agent Management

Agents submit jobs for execution on the host, monitor jobs, and perform post-processing analysis of completed jobs. The job completion status and the post-processing analysis results are transmitted back to the Server.

You can install multiple Agents, which are managed by a Control-M/Server that assigns jobs to an Agent name that identifies the host.

You can also run and execute jobs on hosts where Control-M/Agent is not installed, as described in Agentless Hosts.

The Agent communicates with the Server using HTTPS protocol (port 443). If your organization blocks access to the Internet, contact your network administrator to grant outgoing access to the following URLs:

*.controlm.com:443 (HTTPS protocol, outgoing only)
*.amazonaws.com:443 (outgoing only)

If the Agent is installed on Linux, BMC recommends you use non-root mode. For more information, see set_agent_mode.

In the Configuration domain, you can install, monitor, search, and manage Agents in your environment.

The following describes the specific Agent actions you can perform:

Install: Installs the Agent on your environment, as described in Agent Installation.
Edit: Enables you to configure the following Agent parameters, as described in Configuring Agent Parameters.
Ping: Tests the connectivity to the Agent.
Recycle: Shuts down and starts up the Agent.
Disable: Disables all Agent actions.
Delete: Deletes the Agent from your environment. To fully remove it, you must uninstall the Agent from the host.

Automatic Agent and Agentless Host Discovery

Automatic discovery enables you to automatically discover an Agent that was installed but not added to the Agent list in the Configuration domain. Control-M searches for existing Agents in your environment when you run a job with a user-defined hostname. If Control-M cannot find an Agent in your environment with the defined hostname, Control-M then automatically discovers and adds this Agent to the Agents list in the Configuration domain after it verifies that Control-M/Agent is installed. However, if Control-M/Agent is not installed on the defined hostname, Control-M then automatically applies the default Agentless Host settings to the host and adds it as an Agentless Host.

This option is enabled by default. To disable this ability, you must set the HOST_AUTODISCOVER system parameter to N, as described in Scheduling and Execution Parameters.

To define default Agentless Host settings, see Defining Default Agentless Host Settings.

Adding an Agent

This procedure describes how to add an Agent component, which enables you to connect it to a self-hosted Control-M/Server via specific communication parameters. After you add the Agent to your environment, you can define and run jobs on the Agent through the Control-M/Server that manages it.

Before You Begin

Begin

From the icon, select Configuration.

The Configuration domain opens.
From the drop-down list, select Agents.

The Agents tab ppears.
Click Add Agent.

The Add Agent dialogue box appears.
For each field, define the required parameters, as described in Agent General Parameters.
(Optional) Click Test to test the Agent connection.

The test completes successfully.
Click Add.

The Agent appears in the Agents tab table.

Configuring Agent Parameters
