Overview
As teams iterate, deploy code, and make changes to their applications and services, identifying the exact change that caused a spike in errors, increased latency, or slower page load times can be challenging. Use Change Overlays to visualize changes on your dashboard like deployments or feature flags, and quickly correlate performance issues with them.
Overlay changes on graphs
To get started, click Show Overlays in the upper right corner of your dashboard. Now you can enable the Change Tracking timeline and change overlays on timeseries widgets.
When actived, the Service search bar will display the Most Relevant service by default. Datadog automatically selects the service most frequently referenced in the queries supporting the widgets on the dashboard.
Override the automatic service detection by using the search bar to find the service of interest.
All changes displayed on the change timeline and as overlays tie back to the selected service.
Use the Show On dropdown to limit change overlays to relevant widgets, or shown them on all widgets on your dashboard.
To view additional details or take additional actions, click on a change overlay or change within the change timeline.
FAQ
What are deployments changes scoped to?
For APM deployments, an env must be specified. If you have an env or datacenter template variable set in your dashboard, deployments are filtered to match the selection. Otherwise, the env defaults to prod.
