We have,

two GoLang microservices(http server)

&

one GoLang background program(running infinite loop).

Within micro-service, we have added diagnostic endpoint point(http port), to provide health-check of service. Grafana monitoring tool talks to this diagnostoc end point.

For background program,

How to diagnose health-check(up or down) of backend program? application healthcheck monitoring

Solution

  • You can add a small HTTP server in the background program, which responds to health-check requests.

    When you get a request, you can verify a state which is updated in the infinite loop (it actually depends on your custom logic).

    This way you can inspect the health of your program in grafana as well (consistency).
