System Center 2012-Operations Manager uses detection signals to monitor the communication channels between the proxy and the main management servers of the proxy. The detection signal is a packet sent regularly from the proxy to the Management Server. By default, the packet is sent every 60 seconds and port 5723 (UDP) is used ).

If the agent fails to send detection signals four times, an "Health Service detection signal failed" alarm is generated, and the Management Server attempts to ping the computer. If the computer does not respond to the Ping, an alarm "unable to connect to the computer" is generated. This process is displayed.

When you see these two alarms, you know that the Management Server cannot contact your computer. When you only see the detection signal failure alarm, you know you can contact the computer, but the agent has a problem.. When the detection signal returns to normal, both alarms are automatically disabled.

By defaultDisabled for the client operating systemLoss detection signals and Ping response alarms. To receive client OS alerts, replace the "Health Service detection signal failed" and "Computer inaccessible" monitors for Windows client OS, to set the "generate alert" parameter to "true ".

You can change the detection signal interval of all agents and the number of lost detection signals of all management servers in "Settings" in the "manage" workspace, as shown in.

The default interval is 60 seconds ,.

By opening the properties of your computer in "Agent Management" or "Management Server" in the "manage" workspace, youIt can also replace the global detection signal interval of a single proxy and the number of lost detection signals of a single management server.. For example, you can increase the interval of detection signals for computers with slow network connections.
