After completing this topic, you can compare a new Run against a baseline Run in Explore to identify regressions and validate that signal behavior falls within the expected range.

​
Before you begin

  • You have a new Run with ingested telemetry data that you want to evaluate.
  • You have at least one historical Run that represents expected behavior to use as a baseline.

​
How baseline comparison works

In Explore, you can load a historical Run as your baseline and plot a new Run alongside it. By plotting the same Channels across both Runs, you can visually compare signal behavior and quickly identify where the new Run diverges from expected behavior.

​
Compare a Run to a baseline

  1. In Sift’s homepage, enter the name of the historical Run you want to use as the baseline in the Search box.
  2. In the Runs table, click the Run.
  3. Click Explore.
  4. Select a Panel type to add to the workspace.
  5. In the Channels tab, click or drag a Channel onto the Panel to plot it.
  6. Click Select data to add the new Run you want to compare.
  7. Plot the same Channel from the new Run to compare it directly against the baseline.
  8. Optional: Open the Time-Alignment tab in the Panel settings to customize the alignment configuration for all plotted Runs.
  9. Optional: Use range controls to zoom into a time range and focus on a specific divergence.
