A 502 Bad Gateway error occurs when Cloudflare is unable to establish contact with your origin web server. There are two possible causes:

• 502/504 from your origin web server: Cloudflare returns a Cloudflare-branded HTTP 502 or 504 error when your origin web server responds with a standard HTTP 502 bad gateway or 504 gateway timeout error. This can be caused by a variety of factors, such as:
  • Excessive server loads
  • Crashes or network failures
  • Applications or services that timed out or were blocked
• 502/504 from Cloudflare: In rare cases, Cloudflare itself may experience a temporary outage or issue that can cause a 502 error. If you believe this is the case, you can check the Cloudflare status page to see if there are any known issues.

Cloudflare is used for website optimization, security, and performance via its content delivery network (CDN). It optimizes a website's speed and reliability and protects against online threats by mediating between its server and visitors.

Even though Prometheus itself is open source and free to download, there are hidden costs you’ll want to budget for: paying for the infrastructure and storage to host/scale it, especially if you keep long-term metrics or run in big environments; the staff time and expertise needed to maintain, scale, and troubleshoot your setup; possible managed service fees if you choose a cloud provider or vendor; and extra costs for backup, long-term storage solutions (like Thanos/Cortex), alerting/visualization tools, and operational overhead that come with DIY deployments rather than a managed observability stack.
