## Logger File-based logging of both the _master_ and _worker_ processes. ### Usage The `logger([path[, level]])` plugin accepts an optional `path`, and optional `level` to control the verbosity of the master process logs. By default the log level is _info_. Outputting to `./logs`: cluster(server) .use(cluster.logger()) .listen(3000); Outputting to `./tmp/logs`: cluster(server) .use(cluster.logger('tmp/logs')) .listen(3000); Outputting to `/var/log/node` with a log level of `debug`: cluster(server) .use(cluster.logger('/var/log/node', 'debug')) .listen(3000); Generated files: master.log workers.access.log workers.error.log
