Workers - See every release and gradual deployment on Workers Metrics charts

<p><a href="https://developers.cloudflare.com/workers/observability/metrics-and-analytics/">Workers Metrics</a> charts now show every release in the selected time range, including the full progression of <a href="https://developers.cloudflare.com/workers/versions-and-deployments/gradual-deployments/">gradual deployments</a>. This makes it easier to correlate changes in memory, CPU time, errors, or latency with the code that was serving traffic.</p> <img src="https://developers.cloudflare.com/cdn-cgi/image/onerror=redirect,width=2400,height=1350,format=webp/_astro/2026-09-25-release-flow-memory-usage.C5rkO7VY.png" alt="Memory usage chart showing a gradual deployment as a shaded rollout band" loading="lazy" decoding="async" width="2400" height="1350"> <p>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.</p> <img src="https://developers.cloudflare.com/cdn-cgi/image/onerror=redirect,width=2400,height=1350,format=webp/_astro/2026-09-25-release-flow-invocations.BvQMAKnw.png" alt="Invocations chart showing traffic shifting from the previous version to the new version during a gradual deployment" loading="lazy" decoding="async" width="2400" height="1350"> <p>Use these annotations to:</p> <ul> <li><strong>Find when a regression started</strong> — See which traffic percentage was configured when errors, latency, CPU time, or wall time changed.</li> <li><strong>Compare rollout stages</strong> — Check whether a metric changed as more traffic moved to the new version.</li> <li><strong>Confirm rollbacks</strong> — Rollbacks appear as separate release events, so you can check whether metrics recovered after a rollback.</li> </ul> <p>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.</p> <p>To view release annotations, open the <strong>Metrics</strong> tab for your <a href="https://dash.cloudflare.com/?to=/:account/workers/services/view/:worker/production/metrics" target="_blank" rel="noopener">Worker<span class="external-link"> ↗︎</span></a>.</p>
