In-Depth Information
A heartbeat is a UDP packet sent on port 5723 every 60 seconds that Operations Manager
uses to monitor communication channels between the Operations Manager agent and its
primary management server. If the Operations Manager management server fails to receive
four consecutive heartbeats from an agent, two things happen:
■
Operations Manager will generate a Health Service Heartbeat Failure alert, as shown in
Figure 3-32.
■
The management server will attempt to ping the computer that hosts the agent.

Alert properties
If the computer that hosts the agent does not respond to the ping request, Operations
Manager will generate a Failed To Connect To Computer alert. If you see the Health Service
Heartbeat Failure alert, but not the Failed To Connect To Computer alert, you can deduce
that there is a problem with the Operations Manager agent, as the computer itself remains
contactable. Both of these alerts will be closed automatically once heartbeat traffic resumes.
