Chart annotations

Annotations allow you to mark specific dates in your web performance charts.

For example, you could add an annotation when:

• a new release is deployed
• a new image was added to your homepage
• your CDN adds support for a new image format
• you enable HTTP/2 on your server

How to add a chart annotation

1. Right click a chart
2. Click Add Annotation

3. Enter annotation details at the top of the page
4. Click Create

Now the new annotation has been created.

Limiting annotations to specific pages

By default annotations are added to all pages in a project. You can change this using the Apply to dropdown.

• This Project: add the annotation to all pages
• This Subdomain: add the annotation to this hostname, for example app.example.com
• This URL: add the annotation to all pages with the same URL
• This Page: only add the annotation to this specific monitored page

The last three options are only available when you add the annotation from a chart on a specific page. Annotations added from a project-level chart always apply to the whole project.
