Insights: Breakdown Tree View

The breakdown tree section contains your test script in a visual way; most of the components (thresholds, groups, requests...) that you've added in your script will be represented in the same order in the breakdown. This section can help you to:

  • Find failing errors: checks, thresholds and requests.
  • Find the slowest/fastest groups and requests.
  • Visualize custom metrics.
  • Drilling down check, custom and request metrics.

Finding errors

In the top left of the breakdown you'll find a `status filter`. This filter will let you show or hide passed and failed items and the selected filter will only affect the breakdown and nothing else. The error filter will be applied to:

  • Checks
  • Thresholds
  • Requests
  • Groups

To keep things as clear as possible this will be set to only display errors by default.

Moving down in the breakdown you'll see your added groups, checks and requests. To the left of each item in the breakdown you can see the status represented by a red or green border together with a summary of the error rate.

For a group the error rate will be the number of passed or failed checks and requests in that group(including any nested sub groups). Checks and requests will display a percentage of the success rate.

Finding slowest/fastest groups and requests

To the right of each group or request you'll find an aggregated value for the `response time` for that item. This value is based on all requests in that group and will respect the aggregation method selected previously.

To find the slowest(or fastest one) simply click the `Load time` column header and it will sort the breakdown on descending `response time`. Click the header again to change to ascending order.

Drilling down

When you find a group, URL or check that you want to see more information about click the row to expand the metrics section for that resource. If you want to see metrics aggregated for a group you'll find them in the `more` menu to the right of the `load time`.

URL metrics

For a URL you can see the status distribution at the top of the expanded area and beneath you'll find a chart with metrics for that URL.

By default the `response time` will be presented in the chart. To add other metrics either press the name of the visible metric or select one from the `more`menu.

When you find something interesting that you want to compare with other metrics or keep for later you can add that single metric or a group of metrics to the analysis panel. Metrics added to the analysis panel will be persisted if you leave the results page and come back later.

See more: Insights: analysis view.

Checks

The metric chart for a check contains passes and failures. This will give you a good overview of when a check is failing during the test run.

The check passes and failures can be added to the analysis panel in the same way as other metrics. Just open the `more` menu and click `Add to analysis`.

Group metrics

Group metrics are aggregated metrics based on all requests in that group. View them by first expanding the metrics section via the `more` menu. Then you can add and remove metrics in the same way as for URL metrics.

Custom metrics

Custom metrics created in your test script will be available on the root group in the breakdown. By default the three first custom metrics will be displayed when expanding the metrics for the root group. To add more custom metrics use the more menu to the right after expanding the chart.
