Configuring heartbeat event notifications for IBM Control Center

IBM® Control Center uses heartbeat event notifications to monitor the status of WebSphere® Application Server Liberty Core. You can configure the global.properties file to enable or disable heartbeat event notifications for IBM Control Center and specify how frequently IBM Control Center receives heartbeat event notifications. If another heartbeat event is not sent before this interval, and no other Global Mailbox event is received, IBM Control Center reports the server as down.

1. In the <shared_files_dir>/config/ directory, locate the global.properties file.
   Remember: The <shared_files_dir> is the base directory that you specified during installation.
2. Open the global.properties file in a text editor.
3. Specify the value true for the com.ibm.mailbox.controlcenter.heartbeats.enabled property to enable heartbeat event notifications for IBM Control Center.
   The default value is false:

   com.ibm.mailbox.controlcenter.heartbeats.enabled=true

4. Specify a value for the com.ibm.mailbox.controlcenter.heartbeats.minutes property to determine the time interval (in minutes) between each successful heartbeat event notification that is sent to IBM Control Center.
   The default value is 5 minutes:

   com.ibm.mailbox.controlcenter.heartbeats.minutes=5

5. Save the global.properties file.
