--log-backtrace-at traceLocation when logging hits line file:N, emit a stack trace (default :0)
--log-dir string If non-empty, write log files in this directory
--log-flush-frequency duration Maximum number of seconds between log flushes (default 5s)
--logtostderr log to standard error instead of files (default true)
