public class GcpJsonFormatter
extends Formatter

JUL formatter that formats log messages in a single-line JSON that Stackdriver logging can parse.

The structured logs written to STDOUT and STDERR will be picked up by GAE/GKE logging agent and automatically ingested by Stackdriver. Certain fields (see below) in the JSON will be converted to the corresponding Log Entry fields and parsed by Log Explorer.
