@dkozickis could you take another look at this? It seems that the ping package does not always work as expected.

@elpoelma any errors?

@elpoelma any errors?

When testing the library seperately, the ping package would always indicate that the endpoint was not alive (even with other endpoints like https://www.google.com/ etc.).

Hi,

Would it be an option to implement health probes instead of using the ping dependency and killing the app when the ldes is not responsive?

This service already uses a docker image that starts a server. c.f. https://github.com/mu-semtech/mu-javascript-template/blob/master/helpers/mu/server.js#L40

We could also provide different health checks for the app (e.g. /status/am-i-up) and the eventstream (e.g. /status/ldes). C.f. https://hootsuite.github.io/health-checks-api/.
