NAME
ruptime - show status of local machines
SYNOPSIS
ruptime [-a][-r][-l][-t][-u]
DESCRIPTION
ruptime outputs a status line for each machine on the local network that is running the rwho daemon.
ruptime’s status lines are formed from packets broadcast once every 3 minutes between rwho daemons
(see rwhod(1M)) on each host on the network. Each status line has a field for the name of the machine, the
status of the machine (up or down), how long the machine has been up or down, the number of users logged
into the machine, and the 1-, 5- and 15-minute load averages for the machine when the packet was sent.
The status of the machine is reported as ‘‘up’’ unless no report has been received from the machine for 11
minutes or more.
The length of time that the machine has been up is shown as:
days+hours:minutes
Load averages are the average number of jobs in the run queue over the last 1-, 5- and 15-minute intervals
when the packet was sent.
An example status line output by ruptime might be:
machine1 up 1+5:15, 7 users, load 1.47, 1.16, 0.80
The above status line would be interpreted as follows:
machine1 is presently ‘‘up’’ and has been up for 1 day, 5 hours and 15 minutes. It currently has 7 users
logged in. Over the last 1-minute interval, an average of 1.47 jobs were in the run queue. Over the last 5-
minute interval, an average of 1.16 jobs were in the run queue. Over the last 15-minute interval, an aver-
age of 0.80 jobs were in the run queue.
If a user has not used the system for an hour or more, the user is considered idle. Idle users are not shown
unless the -a option is specified.
Options
If no options are specified, the listing is sorted by host name. Options change sorting order as follows:
-l Sort by load average.
-t Sort by up time.
-u Sort by the number of users.
-r Reverse the sort order.
DIAGNOSTICS
no hosts!?!
No status report files in /var/spool/rwho. Next Step: Ask the system administrator to check
whether the rwho daemon is running.
