[gateway] API is down when a healthcheck failed #1807

Closed kevinimbrechts closed 5 years ago

kevinimbrechts commented 5 years ago

Hi, I think there is a problem with Gravitee when a healthcheck failed. In fact, when a healthcheck is down, the API return 503 error. If I disable or if I fix healthcheck, API works again.

Also, it would be interesting to send a mail when a healthcheck is failing. I think this is exist (cf https://github.com/gravitee-io/issues/issues/822) but I didn't find the "ALERTS" section like here https://medium.com/graviteeio/gravitee-io-alert-engine-ae-is-out-f735ea9b6686

Expected Behavior

If a healthcheck failed, an email is sent and the API MUST continue to work properly.

Current Behavior

If a healthcheck failed, API return 503 error when I call her with a REST client.

Steps to Reproduce (for bugs)

  1. Configure healthcheck with a bad assertion
  2. Try to call the API with a REST client
  3. API return a 503 error

Your Environment

Thank you ! And I wish you all a happy new year.

Hi Kevin,

Yes, active health-check is used to manage load-balancing algorithm for a group of endpoints. If health-check is failing for X consecutive times, the endpoint is excluded from the group. If you have a single endpoint and HC fails, that's the reason why you get a 503 from the API gateway.

For alerting, it is an additional addon provided by Graviteesource within support subscription.
