The timeout period defines the maximum time, in seconds, between the receipt of console message traffic from a UNIX or Linux system before the system connection is considered to have timed out. The Operations Sentinel server uses the timeout period property to determine whether its connection with the console is functional.
Operations Sentinel provides a sample heartbeat script located at data-folder\agents\spo_heartbeat. Use this heartbeat script to ensure the Operations Sentinel server receives console messages from the system. You can copy this script to each monitored UNIX or Linux system. The heartbeat script can run in the background in a monitored session from the command line, or you can incorporate the script into the system startup, directing the messages to a specific terminal or device.
The usage syntax is as follows:
spo_heartbeat device [interval]
where:
| device | Is the terminal device where the messages are to be echoed. For example, /dev/console or /dev/pts/3. |
| interval | Is the optional value in seconds for the time between messages. If the interval is not specified, the default value of 60 seconds is used. |
