 These metrics measure both the successes and failures (dcount) of the calling SDK public APIs, for example (mute, join, etc.).

+|----------------------------|----------------------------------------------------------------------------------------------------------------------------|
+| `reliability/api/CreateView/Local` | Measures the reliability of the calling SDK `CreatView/Local` API which renders local video streams. This API is required for user's to see their local video stream. | 
+| `reliability/api/Join`             | Measures the reliability of the calling SDK `Join` API. When this API succeeds, a user's client is admitted to an existing call or meeting.                 |
+| `reliability/api/StartVideo` | Measures the reliability of the calling SDK `StartVideo` API which begins streaming video from the calling client to remote participants. When this API succeeds a user's client successfully sends video. |
+| `reliability/api/AcceptIncomingCall` | Measures the reliability of the calling SDK `AcceptIncomingCall` API which indicates the client successfully accepted and connected to an incoming call. |
+| `reliability/api/CreateView/Remote` | Measures the reliability of the calling SDK `CreateView/Remote` API which indicates the client successfully renders incoming video from a remote participant. |
+| `reliability/api/StopVideo` | Measures the reliability of the calling SDK `StopVideo` API which indicates the calling SDK successfully stopped streaming video to remote participants. |
+| `reliability/api/CallAgentInit` | Measures the reliability of the calling SDK `CallAgentInit` API which indicates the calling SDK successfully created the `CallAgent` object. If this fails, the reliability/api/Join or reliability/api/StartCall APIs can not be triggered. |
+| `reliability/api/StartCall` | Measures the reliability of the calling SDK `StartCall` API which indicates the calling SDK succseffuly initiated a new call.  | 
+| `reliability/api/Drop` | Measures the reliability of individual call legs by identifying which call legs were dropped unexpectedly after they successfully connected to a call. Focuses on participants call legs that successfully connected to a call and checks if the call legs were later dropped due to specific error codes.  |
