AccessLogPolicy Config

Accesslog Policy plugin is a stateful http log sampler. It decides whether a request is logged based on the following rules. 1. All requests resulting in errors are logged. 2. First successful request within logwindowduration from a specific source ip (source principal) is logged. The plugin records its decision in the istio.accesslogpolicy attribute with a value of “no”. A downstream plugin may honor the the attribute. For example, Stackdriver plugin will not produce an access log entry if this attribute is set.
