Tutorial: Run a query that produces a time series visualization

When you run a query that uses the bin() function to group the returned results by a time period, you can view the results as a line graph, stacked area graph, pie chart, or bar chart. This helps you more efficiently visualize trends in log events over time.

To run a query for visualization

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

  2. In the navigation pane, choose Logs, and then choose Logs Insights.

  3. In the Select log group(s) drop down, choose one or more log groups to query.

    If this is a monitoring account in CloudWatch cross-account observability, you can select log groups in the source accounts as well as the monitoring account. A single query can query logs from different accounts at once.

    You can filter the log groups by log group name, account ID, or account label.

  4. In the query editor, delete the current contents, enter the following stats function, and then choose Run query.

    stats count(*) by bin(30s)

    The results show the number of log events in the log group that were received by CloudWatch Logs for each 30-second period.

  5. Choose the Visualization tab.

    The results are shown as a line graph. To switch to a bar chart, pie chart, or stacked area chart, choose the arrow next to Line at the upper left of the graph.
