Operations Sentinel does not draw a connection line to the network to represent Operations Sentinel. Instead, if the connection to Operations Sentinel is down, the image representing the object is surrounded by a dashed connection line.
Likewise, Operations Sentinel does not draw a line to represent the connection between OS 2200 consoles and OS 2200 systems. Instead, if the host connection is down, the image representing the console is surrounded by a dashed connection line.
A separate line is drawn between an object and its components (for example, an OS 2200 system and its consoles, or a server and its systems). Operations Sentinel does not draw the line if they are in separate sections of the topology (implicit versus explicitly located).
Connection State Lines
A solid green line around the system or component indicates an active connection.
A dashed red line around a system or component indicates the it is disconnected or the connection state is unknown.
No line around the system or component indicates that it is unmonitored.
An administrator can customize the color and visibility of this line using the topology editor dialog in Department and Enterprise editions.
Disconnected Systems or Components
For arbitrary systems, an image in a topology might be unconnected from all other images in a topology for one or more of the following reasons:
Operations Sentinel does not support an architected interface to the system.
Terminal emulation access only is defined for that system, which might be any arbitrary system for which monitoring is not fully integrated with Operations Sentinel.
The system is only being monitored by application software external to Operations Sentinel.
User-supplied external software can raise alerts using the spo_event command, the Single Point Interface Pipe (spo_pipe), or an Event Server API client that causes the unconnected system image to change color in a topology. The Operations Sentinel Trap Service can receive SNMP traps from many sources and translate these traps into alert event reports.
