sed '/^[<spc><tab>]*$/d'

will remove all empty lines (that is: lines with no characters and lines consisting only of whitespace). Replace "<spc>" and "<tab>" with literal space/tab characters.

TORRUS_MONITOR(8)						      torrus							 TORRUS_MONITOR(8)

NAME
monitor - Torrus Monitor. SYNOPSIS
torrus monitor --tree=TREENAME [options...] DESCRIPTION
This command starts the Monitor process for the tree TREENAME. By default it forks into a daemon, sets the log output file to /var/log/torrus/monitor.TREENAME.log, performs one monitoring cycle, and sleeps until the next cycle is scheduled. In daemon mode the log file can be reopened by sending it a SIGHUP signal. OPTIONS
--nodaemon Prevents the process from becoming a daemon and sets the log to STDERR. --runonce Instructs the script to run once and exit. Implies --nodaemon. --delay=N Makes the daemon sleep for N minutes before starting the first cycle. This would happen on the daemon startup and also after each configuration recompilation. For example, when monitor and collector start simultaneously, the collector needs some time to retrieve the data being monitored. --debug Sets the log level to debug. --verbose Sets the debug level to info. --help Displays a help message. FILES
/etc/torrus/conf/torrus-siteconfig.pl Torrus site configuration script. /var/log/torrus/monitor.TREENAME.log Monitor's log for the tree TREENAME. SEE ALSO
