Access logging

    • Any number of access logs per connection manager or tcp proxy.
    • Customizable access log filters that allow different types of requests and responses to be written to different access logs.

    Envoy supports pluggable access logging sinks. The currently supported sinks are:

    • Asynchronous IO flushing architecture. Access logging will never block the main network processing threads.

    gRPC

    • Envoy can send access log messages to a gRPC access logging service.
