Gustavo Leite, a mobile developer at ilegra, discusses the health check API, which executes tests to determine the current state of a service through a health endpoint. The canary endpoint is highlighted as a simplistic tool that monitors connectivity status and latency across various service dependencies. The document also references various health endpoint monitoring patterns and provides links for further information.

“If it is green, it does not mean
your service is available. But if it
is red (your canary is dead) then
you definitely have a problem.”
