healthchecks/dashboard repository overview

⁠Healthchecks.io Status Dashboard

A standalone dashboard page showing the status of the checks in your Healthchecks.io⁠ account.

See a live example dashboard here⁠.

• Single page, no external dependencies.
• Plain HTML, JS and CSS. Fork it and hack on it – no build tools or dev environment needed.
• Live-updates every 5 seconds.
• Can display checks from multiple projects.
• Uses Healthchecks.io read-only API keys, does not expose ping URLs.

⁠Dark Theme

⁠Light Theme

⁠How To Use

• Fork the repository.
• Edit index.html and replace the API keys in <h1> tags. Be sure to use the read-only API keys!
• Optionally, you can tweak the colors, font sizes and layout.
• Publish the index.html file to a web server (Github pages, S3 bucket, Netlify, ...), or simply open it as a local file in your browser.

⁠Specifying API Keys in the URL

As an alternative to editing index.html, the projects and their API keys can be specified in the URL. Put them in the fragment identifier (after the "#" character) as amperstand-delimited "apikey=title" pairs. Example:

index.html#UKsc30GIblRMKKN4BEPXcBNLa8bx4grU=Monitoring&uKatH7z6dSuN2Zyf1luRCmPDkw3fw2U0=Demo

The light theme is used by default, but the dark theme can also be specified via the URL:

index.html#theme=dark

⁠Security

If you decide to make your dashboard public, your read-only API key will become public as well. Using the read-only API key, anybody can fetch basic information about checks in your project. This includes, for each check:

• name, tags and description (even though tags and descriptions are currently not being shown on the dashboard)
• check's schedule (period, grace time, cron expression + timezone)
• current status (new / up / down / paused)
• precise time of the last ping
• precise time of when the next ping is expected
• total number of pings the check has received

Here are the things that the read-only API keys cannot do:

• the ping URLs are not exposed. You are not risking unexpected pings from random visitors
• no write access: cannot update or delete the existing checks, cannot create new checks in your project

⁠Docker image

There is an official Healthchecks.io Status Dashboard Docker image⁠ on Docker Hub ready to use. The image is automatically built⁠ on each commit.

The image starts a lightweight Caddy Webserver⁠ with the dashboard at the webserver's root. The example below starts a one-off, intercative container serving on port 8080 (CTRL+C to stop it):

$ docker run --rm -it -p 8080:2015 healthchecks/dashboard
