ID: 10372 Title: stunnel: Improve logging of the daemon Component: Other Components Level: 1 Class: Bug fix Version: 1.7.0i1 The stunnel daemon instance, which is used once encrypted livestatus is enabled, is now not logging to syslog anymore. It only logs to the sites log file var/log/stunnel-server.log. The default log level has been changed from notice to warning.
