# Monitor Kinesis Video Streams with WebRTC
<a name="kvswebrtc-monitoring-cw"></a>

You can monitor an Amazon Kinesis Video Streams with WebRTC using Amazon CloudWatch, which collects and processes raw data from Amazon Kinesis Video Streams with WebRTC into readable, near real-time metrics. These statistics are recorded for a period of 15 months, so that you can access historical information and gain a better perspective on how your web application or service is performing. 

Amazon Kinesis Video Streams provides the following metrics:

**Topics**
+ [Signaling metrics](#kvswebrtc-monitoring-cw-signaling)
+ [TURN metrics](#kvswebrtc-monitoring-cw-turn)
+ [WebRTC ingestion metrics](#kvswebrtc-monitoring-cw-ingest)

## Signaling metrics
<a name="kvswebrtc-monitoring-cw-signaling"></a>

This section provides information on how to monitor and troubleshoot signaling-related issues using CloudWatch Logs.


| Metric name | Description | Unit | Dimensions | 
| --- | --- | --- | --- | 
| Failure | '0' is emitted if the Operation mentioned in dimension returns 200 status code response. '1' otherwise. | Count | Operation, SignalingChannelName | 
| Latency | Measures the time it takes for the service to receive a request and return a response. | Milliseconds | Operation, SignalingChannelName | 
| MessagesTransferred.Count | The total number of messages sent and received for a channel. | Count | SignalingChannelName | 

The `Operation` dimension applies to the following APIs:
+ ConnectAsMaster
+ ConnectAsViewer
+ SendSdpOffer
+ SendSdpAnswer
+ SendCandidate
+ SendAlexaOfferToMaster
+ GetIceServerConfig
+ Disconnect

## TURN metrics

This section provides information on how to monitor and troubleshoot TURN-related issues using CloudWatch Logs.


| Metric name | Description | Unit | Dimensions | 
| --- | --- | --- | --- | 
| TURNConnectedMinutes | '1' is emitted for each TURN allocation that is used to stream data through in a minute. | Count | SignalingChannelName | 

## WebRTC ingestion metrics
<a name="kvswebrtc-monitoring-cw-ingest"></a>

This section provides information on how to monitor and troubleshoot WebRTC ingestion-related issues using CloudWatch Logs.


| Metric name | Description | Unit | Dimensions | 
| --- | --- | --- | --- | 
| Failure | '0' is emitted if the Operation mentioned in dimension returns 200 status code response. '1' otherwise. | Count | Operation, SignalingChannelName | 
| Latency | Measures the time it takes for the service to receive a request and return a response. | Milliseconds | Operation, SignalingChannelName | 
| TotalBitrate | Total bitrate sent. If Role is specified, this represents the total bitrate sent by the MASTER participant or the aggregate total bitrate sent by the VIEWER participant. | bps | Operation, SignalingChannelName, Role | 
| TotalPacketCount | Total packet count sent. If Role is specified, this represents the total bitrate sent by the MASTER participant or the aggregate total bitrate sent by the VIEWER participant. | Count | Operation, SignalingChannelName, Role | 
| WebRTCRecordingMinutes | The number of WebRTCRecordingMinute occured for a channel. | Count | Operation, SignalingChannelName, Role | 
| WebRTCViewerMinutes | The number of WebRTCViewerMinute occured for a channel. | Count | Operation, SignalingChannelName, Role | 

The `Operation` dimension applies to the following APIs:
+ JoinStorageSession
+ JoinStorageSessionAsViewer

`Role` dimension:
+ MASTER
+ VIEWER
