Tutorial: Run a Query with an Aggregation Function

In this tutorial, you run a query that returns the results of executing aggregate functions on log records.

To run an aggregation query

1. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.

2. In the navigation pane, choose Insights.

3. Choose a log group.

4. In the query editor, delete the query that is currently shown, then type the following and choose Run query. Replace fieldname with the name of a field that appears in the Discovered fields area on the right of the screen.

   stats count(*) by fieldname

   The results show the number of log events in the log group that were received by CloudWatch Logs that contain each different value for the field name you chose.
