Snowplow missing few events


Setup : we’ve configured Snowplow on Elastic Beanstack and sends app attribution events to snowplow.

Issue : we missing quiet a few events triggered from Adjust to snowplow.

Investigation : we found a elastic beanstack logs saying following warning.

WARN : Environment health has transitioned from Ok to Degraded. ELB health is failing or not available for x out of n instances.

It’s going ON/OFF between INFO and WARN.

and we suspect this could be the potential issue for missing events.

Wonder if anybody can help to identify/fix issue.
