Monitors Do Not Show Colors in the Element Monitor Window of the Control Center

Farm-specific monitors might not appear on the Control Center. This condition could be caused by one of the following problems:

• Agent processes are not running on the servers.

• The mapping between the gw-mon-vip and the IP address of the Control Center server software is not set in the /etc/hosts file on the control plane server.

• The listener on the Control Center is not running. See Control Plane Server-to-Control Center Messages Not Working for information on how to verify this condition.

Figure 7–2 shows the sequence of steps for you to follow to diagnose and resolve the above error condition. See Control Plane Server-to-Control Center Messages Not Working for details on how to resolve these problems.
