Feature
See every release and gradual deployment on Workers Metrics charts
Workers Metrics charts now show every release in the selected time range, including the full progression of gradual deployments. This makes it easier to correlate changes in memory, CPU time, errors, or latency with the code that was serving traffic.
A gradual deployment appears as a single rollout across the chart, with shading that increases as more traffic moves to the new version. Hover over a rollout to see the previous and new versions, the rollout duration, and the traffic percentage configured at each step.
Use these annotations to:
- Find when a regression started — See which traffic percentage was configured when errors, latency, CPU time, or wall time changed.
- Compare rollout stages — Check whether a metric changed as more traffic moved to the new version.
- Confirm rollbacks — Rollbacks appear as separate release events, so you can check whether metrics recovered after a rollback.
Direct deployments that send 100% of traffic to a single version still appear as individual markers. Nearby direct deployments are grouped to reduce visual clutter. Versions that are only uploaded, or only configured at 0%, do not appear on metrics charts.
To view release annotations, open the Metrics tab for your Worker.
