On-Demand ADM features
The On-Demand ADM is a feature-rich display showing connections between systems and the overall health of those connections.

Map nodes
Each map node, which may actually be several systems known as a rollup node, provide one or more of the following.
Application name. Rollup nodes only show the application name.
IP address.
DNS name, if resolvable.
All starting nodes for a query have a blue border. An On-Demand ADM query may be from a client IP address or DNS name, server IP address or DNS name, or IP (client-server) Pair. Additionally, an application (for example, HTTP) may be optionally included. The resulting map shows you the connected and interdependent systems from the perspective of the starting system. If it is a server, you will see all client systems for that server. If an application was included you will see only the clients that rely that application for the server. Conversely, if it is a client, you will see all of the servers it connects to.
Click the Application Name or IP or DNS address to see the details of each system’s connection.
Rollup nodes are for a single application and have a number inside them showing how many systems are related. A maximum of five (5) systems are combined into a rollup node. If there are more than five connections, the worst five performers are included.
Figure 40: Connection Status
Connection StatusConnection Status
Hover over a DNS name in Connection Status to see the underlying IP address.
You can choose to break out some or all of the rolled up connections. Click the connection and use Break out connection Break Out Connection icon. This allows you to see any failing or marginal connections separate from the rest of the well-performing systems.
Line colors
Colored lines show a connection's threshold status (exceeds, marginal, or acceptable). The line colors of connections with end user scores will be based off of the worst score seen within the connection. If a connection does not have scores, then the connection will use the highest deviation from baseline threshold value of Network Client Delay or Application Client Delay. If a node is comprised of multiple servers, the status of the worst of the worst performing system determines the line color. For example, if a rollup node has five systems and four systems report an acceptable (blue) connection and one system is over the critical (red) threshold, then the line is red. Click the line to see the details of each server's connection.
The connecting lines interact with the thresholds set in Configuration > Thresholds.
Blue lines indicate no marginal or critical threshold has been crossed.
Yellow lines indicate a marginal threshold has been crossed.
Red lines indicate a critical threshold has been crossed.
Gray lines indicate not enough data was present to make a determination of status or a threshold was not defined or unavailable.
Map size
Some maps can be quite large and you will not be able to see the entire structure at the default scaling on your monitor. You can use your mouse wheel to zoom the map in or out. You can also click the map and drag the entire structure around to see more or focus on a specific section of the map.
Maps can be expanded up to five levels deep. Up to three levels are shown by default.
To assist you in isolating and troubleshooting your problem, a map shows up to 500 connections, many of which may be part of several rollup nodes.
