Thought experiment
Server monitoring at Margie's Travel
Y ou are working on some issues related to the monitoring of server operating sys-
tems at Margie's travel. Specifically:
■ You have deployed the Operations Manager agent to 10 new servers running the
Windows Server 2012 R2 operating system. Each of these servers is shown in the
Monitoring console as having a healthy agent, but is also listed as not monitored.
■ In the last day, two servers have switched from having their health statuses dis-
played in green in the Monitoring workspace of the Server Manager console, to
having their health statuses displayed in gray.
With this information in mind, answer the following questions:
1. What steps can you take to ensure that all of the computers with the Windows
Server 2012 R2 operating system are no longer listed as not monitored?
2. Which service should you check first, on the two servers with a gray health
status?
Objective summary
■ An agent may show a server to be in a not monitored state because the management
pack of the host operating it is not installed on the Operations Manager management
server.
■ Maintenance mode suspends rules and monitors, notifications, automatic responses,
state changes, and new alerts.
■ An Health Service Heartbeat Failure alert will be triggered if the Operations Manager
server fails to receive four consecutive heartbeats from an agent.
■ When a Health Service Heartbeat Failure alert is triggered, the Operations Manager
server attempts to ping the computer. If the computer does not respond to the ping
request, a Failed To Connect To Computer alert will be raised.
■ An ACS forwarder is installed on a computer that will forward security event logs to an
ACS collector.
■ An ACS collector processes data forwarded from an ACS forwarder, and sends it to the
ACS database.
