Dynamic Labels

Dynamic Labels

Until now, you may have noticed that the labels in the graph legend have never been updated. While you can manually edit them, doing so for multiple metrics is not ideal. In this section, we will explore how to automatically update labels without manual changes.

1. Clear the previous expressions.

2. Remove all Filters and click All to return to the namespaces.

3. Navigate to the CWAgent namespace.

4. Select the following dimensions: ImageId, InstanceId, InstanceType, exe, process_name.

5. In the search bar, enter the following:

   • exe=cloudwatch
   • MetricName=procstat_memory_rss (specifying the exact metric name).

6. Click Graph search to display the graph.

7. Switch to the Graphed metrics tab.

   • Expand Add dynamic label.
   • Expand All labels.
   • Select PROP(‘Dim.DimName’).

You will see that the graph labels have been updated.

8. Modify the label expression as follows:

${PROP('Dim.exe')} - ${PROP('Dim.InstanceId')} - ${PROP('MetricName')}

The labels are now displayed in the updated format.
