AppSpeed Topology Overview

The topology tables show the relationships between the services and servers detected on the network, and the dependencies between applications. This chapter includes the following topics:

Analyze an Object
You can select an object in the AppSpeed topology and view its details on the Analysis page. Procedure
u
Select the object in the topology table and click Analyze.
The Analysis page for the selected service or server appears.
Scalability Considerations for AppSpeed Monitoring
AppSpeed is a real-time service performance tool that collects, analyzes, and stores substantial volumes of data per second. Various parameters affect AppSpeed performance.
n n n n n
The number of probes deployed The number of monitored services The number of monitored servers The number of transactions The volume of monitored network traffic
The main factors affecting scalability in AppSpeed are the number of overall monitored objects and the number of transactions that are being monitored. AppSpeed reduces the number of transactions for each service as more services are mapped. This number can be reduced to as few as 50 transactions for each service. AppSpeed stops detecting new servers after the number of monitored servers exceeds 500, or the number of IP addresses and ports in the monitored network exceeds 3000. It also stops mapping new services if the number of monitored services exceeds 100.

Editing AppSpeed Topology
AppSpeed maps servers and services topology from the network traffic monitored on the deployed hosts. You might want to change the topology, for example, to merge two separately mapped services or to view a single mapped service as two separate services, depending on the servers on which it runs. If you split, merge, or remap a service, the historical monitoring and configuration data of the servers or service roots, such as thresholds, is reset. You might also want to remove objects because they are obsolete or less relevant.
Split a Service
A service can be split so that it can be monitored as two separate services. For example, in a server-based scenario you might want to split the monitoring process of a service that is running on a staging server and on a production server, so that they are monitored as two separate services. A service is split according to either the server on which it is running, or on its service roots. A service root is a transaction, usually a database or a domain, in the service that all subordinate transactions have in common. For example, in a service root-based scenario, you might want to monitor two databases that were originally mapped under a single service, as two separate services. 5 6 In the confirmation dialog box, select the servers or service roots to split from the service. Type a name for the new service and click Split.
Merge Services
You can merge two or more services so that you can monitor them as a single service. [. . . ] To specify a date and time, rather than a preset time period, select Manual. 4 (Optional) To view the events for a specific service, select the check box of the service in the table and click View Details. a b In the view selection bar, click Events to see additional information for the service event you selected. (Optional) To display or hide transaction-specific events, select or deselect the Show Transactions check box.
View Event Details
You can view the details of a single event, including the key performance indicators of the object for which the event was generated. [. . . ]
