A business transaction offers a view of application performance that cuts across the environment, reflecting all services that participate in fulfilling the transaction. Another way of viewing application performance, however, focuses on the performance of a particular service independently of the business transactions that use it. 

Like business transactions, service endpoints give you key performance indicators, metrics, and snapshots. However, they provide that information exclusively in the context of that service, omitting business transaction context or downstream performance data. 

Monitor Service Endpoints

From the Application navigation menu in the Controller, click Service Endpoints to view a list of service endpoints with key performance metrics. Service endpoints that have performance data during the selected time range appear in the list. Use the filter view options to show inactive service endpoints for the time range. Other view options include showing transactions of a certain types or ones that exceed a configurable average response time, among others.

The Actions menu lets you view, delete, and exclude selected service endpoints. Excluding service endpoints from this menu hides the service endpoint from the list. To completely disable metric collection for the service endpoint, create an exclude rule. See Service Endpoint Detection.

Diagnostic sessions are not intended to run in the context of a service endpoint alone. Therefore you can't directly start a diagnostic session from a service endpoint. If you run a diagnostic session on the business transactions that include calls to the service endpoint, the transaction snapshots from these diagnostic sessions appear in the service endpoint dashboard.

Service Endpoint Limits

A service endpoint adds a small amount of system overhead. Agents capture approximately three metrics per service endpoint, so monitoring each service endpoint results in additional metric traffic.

To prevent the possibility of a boundless expansion of service endpoints, the Controller and agent configurations apply the following limits:

Service Endpoint Metrics

Service endpoint metrics appear under Service Endpoints in the metric browser. Service endpoint metrics are subject to the same operations as other metrics, including those around metric registration, metric rollups for tiers, and limits on number of metrics. Custom metrics are not available for service endpoints.  

Customize Service Endpoints

For Java applications, AppDynamics automatically detects and registers service endpoints. For either Java or .NET, you can configure custom service endpoint detection rules.

For information on customizing service endpoints, see Service Endpoint Detection.
