Traffic tap, streaming Envoy access logs in Istio
Istio, and in general the service mesh has changed the way of service to service communication (from dumb pipes and smart endpoints to sidecar-to-sidecar). While this has lots of benefits, it can increase the complexity of troubleshooting microservice to microservice communication. One of the typical places developers are checking when comes to troubleshoot is the Envoy sidecar proxy container’s access logs, both on the source and destination side. With the increased number of microservices deployed to distributed environments, this process can be tedious, and it’s very inconvenient trying to pair source and destination access log pairs.
