In a topology, each system and console is represented by a two-part image and corresponding label. For example

The larger part of the image indicates, by shape and color, the most severe alert for the object that has not been marked as “seen.” In this example, the orange triangle indicates there is a major alert. The alert images are as follows:

The second, smaller image, which is superimposed on the first part, indicates the type of object. This image is typically different for each object class.

Although Operations Sentinel provides default images, your site's Operations Sentinel administrator can customize these images. The default images are as follows:

Icon	Managed Object Represented
	Arbitrary system
	MCP system
	OS 2200 console
	OS 2200 system
	Servers
	UNIX/Linux system
	Windows system
	QProcessor System
	JProcessor System
	Consolidated Specialty Engine System
	ePortal System
	VTL Subsystem
	TProcessor System

If the alert server goes down, you cannot see any of the alert icons in a topology. Only the managed object images are displayed.
