   • On the APPLICATION SUMMARY DASHBOARD, expand the service you're interested in and select see all.

     

   • In the service view, select the Tag Spotlight tab.

4. Use the bar charts under the request and errors and latency time-series charts to view RED metrics for each indexed span tag.

You can switch the histogram view for these metrics. Select a bucket to drill down to the sessions belonging to the bucket. Select the Sessions tab to drill down to the sessions belonging to the bucket.

To understand the source of an incident use 1 of these options to drill down into indexed span tags for a selected service:

• Select the menu on the top left of the bar chart section to select which metrics to display for any indexed span tag.

• Select a span tag value then select Add to filter to filter the RED metrics charts to spans containing that value.

• Hover over the RED metrics charts to view a summary of metrics for the specified time. The resolution of data for the RED metrics chart is 10 seconds.

• Select within the RED metrics charts to load example traces for the time you selected.

• Select a span tag card header to add the top 5 span tag values in the card to the RED metrics charts.
