PerfStack — Multi-Metric Correlation

PerfStack is a diagnostic workspace that lets you stack multiple performance metrics from different devices onto a single shared timeline. By aligning metrics on the same X-axis, you can see whether a performance event on one device correlates with an event on another.

How PerfStack Works​

The Devices & Metrics panel on the left lists all monitored devices and the metrics available for each. Click a metric to add it to the timeline as a new chart row.

All charts share the same time axis — zooming or panning moves all charts simultaneously, making it straightforward to correlate events across devices.

Adding Metrics to the Timeline​

  1. Expand a device in the left panel.
  2. Click the metric you want to add.
  3. A new row is added to the PerfStack timeline showing that metric over the selected time range.
  4. Repeat for as many devices and metrics as needed.
