Feature: Filtering Rule for HTTP requests payload (like on emails) about healthchecks HOT 1 OPEN

Hello @exetico, thanks for the suggestion and for the examples.

Are you working with Xen Orchestra? Looking at its docs, there appears to be an email alerts functionality: https://xen-orchestra.com/docs/advanced.html#alerts Perhaps you can use that, and the existing email keyword filtering functionality?

Doing complex evaluation of JSON messages (e.g., if field x is "foo" and field y is "bar") is out of scope for this project.

Interestingly, somebody semi-recently suggested Healthchecks could run client-supplied WASM code to process incoming requests. I think this would be a perfect use case for something like that, but I currently have no near-term plans to add that. Perhaps sometime in the future, if running client's WASM becomes industry standard, and expected "table-stakes" feature, and is easy to implement.

You could look into using AWS Lambda or Cloudflare Workers or a similar FaaS: XO would send the webhook to your function. The function would parse the JSON, check the fields for correct values, and then call Healthchecks' success or failure URL.
