# Viewing OS metrics using CloudWatch Logs
<a name="USER_Monitoring.OS.CloudWatchLogs"></a>

After you have enabled Enhanced Monitoring for your DB instance or Multi-AZ DB cluster, you can view the metrics for it using CloudWatch Logs, with each log stream representing a single DB instance or DB cluster being monitored. The log stream identifier is the resource identifier (`DbiResourceId`) for the DB instance or DB cluster.

**To view Enhanced Monitoring log data**

1. Open the CloudWatch console at [https://console.aws.amazon.com/cloudwatch/](https://console.aws.amazon.com/cloudwatch/).

1. If necessary, choose the AWS Region that your DB instance or Multi-AZ DB cluster is in. For more information, see [Regions and endpoints](https://docs.aws.amazon.com/general/latest/gr/index.html?rande.html) in the *Amazon Web Services General Reference*.

1. Choose **Logs** in the navigation pane.

1. Choose **RDSOSMetrics** from the list of log groups.

   In a Multi-AZ DB instance deployment, log files with `-secondary` appended to the name are for the Multi-AZ standby replica.
