NAME
       ruptime - show status of hosts in the local area network

SYNOPSIS
       ruptime [ -a ] [ -r ] [ -t | -u | -l ]

DESCRIPTION
       At some installations, each system in a local area network runs the
       rwhod agent, which exchanges status information at three-minute
       intervals with the other systems in the network. Use ruptime(1C) to
       find out, from the rwhod agent running on your host, the status of
       other network hosts. The displayed information includes whether a
       host is up or down and, for hosts that are up, the time up, number of
       logged-in users, and load averages (average number of jobs in the run
       queue) for 1-minute, 5-minute, and 15-minute intervals. See the
       example, below.

       Whether rwhod runs on LAN hosts (by default it does not) is left to
       the discretion of the system or LAN coordinator.  If no rwhod process
       is running on your host, typing ruptime displays this message: Rwhod
       does not appear to be running.

       If eleven minutes have elapsed since rwhod has received a report from
       a LAN host, ruptime reports it as down.

       By default, the number of users shown excludes idle users: those who
       have entered no keyboard input for an hour or more. But if you use
       the -a switch, ruptime(1C) includes idle users.

       By default, the listing is sorted alphabetically by hostname. Use
       these switches to alter the order:

       -r   Sort by host in reverse (z-a) order.

       -t   Sort by time up: most to least, with down hosts last.

       -u   Sort by number of users: most to least.

       -l   Sort by load average: busiest to least busy.

EXAMPLES
       Display hosts on the LAN alphabetically by name, giving each's
       up/down status, time up, number of logged-in users, and load averages
       for the most recent 1-minute, 5-minute, and 15-minute intervals:

         $ ruptime <NL>
         sys14    up   10:46,  4 users, load  0.04,  0.03,  0.04
         sys16  down    1:14
         sys10    up 1+02:11,  1 user,  load  2.40,  2.52,  2.43
         $

FILES
       /var/spool/rwho/whod.*   Contain the LAN host information collected
                                by rwhod and displayed by ruptime.
