# Monitoring Amazon Transcribe with Amazon CloudWatch
<a name="monitoring-cloudwatch"></a>

You can monitor Amazon Transcribe using CloudWatch, which collects raw data and processes it into readable, near real-time metrics. These statistics are kept for 15 months, so that you can access historical information and gain a better perspective on how your web application or service is performing. You can also set alarms that watch for certain thresholds, and send notifications or take actions when those thresholds are met. For more information, see the [https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/WhatIsCloudWatch.html](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/WhatIsCloudWatch.html).

## Using Amazon CloudWatch metrics and dimensions with Amazon Transcribe
<a name="monitoring-cwmetrics"></a>

Amazon Transcribe supports CloudWatch metrics and dimensions, which are data that can help you monitor performance. Supported metrics categories include traffic, errors, data transfer, and latency associated with your transcription jobs. Supported metrics are located through CloudWatch in the **AWS/Transcribe** namespace.

**Note**  
CloudWatch monitoring metrics are free of charge and don't count against CloudWatch service quotas.

For more information on CloudWatch metrics, see [Using Amazon CloudWatch metrics](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/working_with_metrics.html).
