Introduction

At cdnjs, we use UptimeRobot to provide continual, minute-by-minute monitoring of our services. This tracks our uptime across a number of different web properties, as well as the response latency on them.

Our public status page is powered by Atlassian Statuspage, but we also like to share raw latency data for our key services on there to help with giving the community real-time insight into performance.

To get the data from UptimeRobot to Atlassian Statuspage, we built this little Cloudflare Worker that runs once per minute, fetching the latest latency data from UptimeRobot, transforming it and sending it over to our Statuspage.

Development

1. Create (or have) an UptimeRobot account with monitors configured.
2. Create (or have) an Atlassian Statuspage account with "post my own data" metrics configured.
3. Create your development.env file. Copy development.env.sample and fill out the information for Sentry, as well as API keys for UptimeRobot & Statuspage.
4. Update the tracked src/data.yml file with your UptimeRobot monitor and Statuspage metric data.
5. Authenticate with Wrangler by running wrangler login.
6. Update wrangler.toml for your account. Use wrangler whoami to get your account ID, update the value in wranglar.toml to match.
7. Develop with the worker by running npm run dev.

Deployments

To deploy to production, run npm run publish:production. As this Worker is based on a cron trigger, it is published in the Workers Dev context and does not need a set zone ID.
