Explicitly set this parameter if you want access control for debugging information.
All debug information is written to the daemon syslog facility.
This paramater is mandatory, there is no other way to specify to failsh what hosts and services it should monitor. By default, failsh goes to the background when started without a debug option. A FIFO can be specified for logfile , in which case the output file is not closed after the state dump is done. An additional benefit is that the file system contain- ing the trace will neve overflow because of failsh . When failsh starts up, it opens a port for monitor clients to connect to.
