NAME
uptimed - daemon to record uptime records SYNOPSIS
uptimed [ -?bv ] [ -e <email> ] [ -i <interval> ] [ -m <count> ] DESCRIPTION
This manual page documents the uptimed program. uptimed is a daemon that records statistics about a machine's uptime. Use the uprecords(1) program to get uptime record statistics. OPTIONS
These command-line options override settings in the configuration file /etc/uptimed.conf -? Show usage -b Create bootid and exit. This option is ignored on BSD systems, because the BSD kernel keeps a static boot time variable in memory so Uptimed does not need to cache this value. -p <file> Write PID to pidfile <file> -e <email> Send mail to <email> at milestones/records -i <interval> Use <interval> seconds for loop -m <count> Log a maximum of <count> entries -t <timespec> Set the minimum uptime to be considered a record -v Show version information SEE ALSO
uprecords(1) AUTHOR
Rob Kaper <cap@capsi.com>. This manual page was written by Alan Ford <alan@whirlnet.co.uk>, for the Debian GNU/Linux system (but may be used by others). It was last modified for uptimed version 0.3.7. May 28, 2004 UPTIMED(8)
