Health Check

Why?

Check the system is working properly, if any errors or anomaly, we want that be detected early than late.

When?

  • check availability
  • check operation correctness
  • check middle-tier or shared service to detect and isolate a failure ...

What?

  • health status of components of an application, db, queue, etc
  • response code
  • response content
  • response time ...

How?

  • expose at least an endpoint for a whole system level check
  • use parameters to check different level of availability
  • obscure and secure the endpoint
  • cache the status and show through an endpoint, in case that's called many times, for example in a dashboard
