How to Configure and Monitor the CA ITCM Infrastructure Health › Understand HM Architecture and Basics › Health Monitoring Components

Health Monitoring Components

The HM feature introduces the following components:

HM Agent:

A persistent module that is installed with the common agent and resides on all the tiers of the CA ITCM infrastructure.

• Interprets the alert configuration on the agents, periodically monitors the occurrence of the alert conditions, and notifies the administrator on detecting the health conditions.

  Note: Alert monitoring is disabled by default. To enable health monitoring, apply a configuration policy.

• Provides the following command-line options for interaction:

  hmagent start 
  

  Starts the HM agent.

  hmagent stop 
  

  Stops the HM agent.

  hmagent status 
  

  Displays whether the agent is running and health monitoring is enabled.

• The HM agent is a service on Windows platforms and a daemon on Linux and UNIX platforms.

Alert Collector:

Alert Collector comprises the following modules:

Web Module

Receives the alerts from the HM agent and copies them to a configured folder.

Persistent Module

Monitors the configured folder and processes new alerts according to the configured alert collector role. For more information, see Configure Alert Collector.

The alert collector has the following requirements:

• The alert collector is only supported on Windows.
• IIS installation is a prerequisite.
• Ensure that the ISAPI extensions and ISAPI filters available under the Application Development option are installed.
• Depending on the DB type to which the alert collector persists the alerts, 32-bit SQL or the Oracle client must be installed.

The web module application hosts HM web services on IIS. This web service is independent of the existing CA ITCM web services functionality and runs in a separate application pool.

The administrator can start, stop, and query the status of the alert collector process from the supported command line. Alert Collector supports the command line options similar to the HM agent.

Alerts on WAC:

DSM Explorer displays a notification when new alerts are raised. The notification contains a hyperlink that launches WAC and navigates to the Alerts page when the unified login is enabled for WAC. If the unified login is not enabled, enter the appropriate user credentials to navigate to the alerts page.
