Only Machine Agent adapter was available before 20.11.0 release. As of release 20.11.0, HTTP SDK is the default adapter for new installations.
Machine Agent Adapter
This adapter connects to HTTP listener of Machine Agent instances installed on every SAP application server. For this adapter to work correctly, the Machine Agent instances must be installed, configured, and run with activated HTTP listener.
- Installation info - Install the AppDynamics Machine Agent
- Configuration info - Connect to AppDynamics Machine Agent
Connection status of this adapter can be validated using t-code /DVD/APPD_STATUS via Machine agent row status under each node. When Machine Agent adapter connection fails, application events are not sent to the controller.
This adapter is also used for forwarding metrics and application events to external systems, see Setup Monitoring of External Systems.
HTTP SDK Adapter
This adapter uses the existing connection from ABAP Agent to HTTP SDK. For this adapter to work correctly, HTTP SDK version 20.11.0 or newer must be used.
Event count limit
The new event API used by HTTP SDK Adapter is currently limited to 100 events per minute in HTTP SDK =< 21.5.0. HTTP SDK => 21.8.0 increases the default limit to 500 events per minute. This cannot be changed by any parameter. If the expected volume of application events exceeds this limit, Machine Agent Adapter needs to be used.
No extra installation or setup steps are needed for this adapter to work. Once the correct HTTP SDK version is installed and running, this adapter will work seamlessly.
- HTTP SDK installation - Install the HTTP SDK
- General HTTP SDK setup - Set Up SAP ABAP Agent
- How to start - Start the AppDynamics HTTP SDK
Connection status of this adapter can be validated using t-code /DVD/APPD_STATUS via HTTP SDK process and HTTP SDK connector row status under each node. When HTTP SDK adapter connection fails, application events will not be sent to the controller.
When HTTP SDK adapter is used with incompatible HTTP SDK version (older than 20.11.0) the following status error message will appear:
