ruptime(TC)
ruptime --
show host status of local machines
Syntax
ruptime [ -a ]
[ -l | -t | -u ]
[ -r ]
Description
ruptime displays a status line for each machine on
the local network; these are formed from packets broadcast
by each host on the network once every 1 to 3 minutes.
Following is the format in which ruptime displays a status line
for each host:
host_name status time #_of_users load_averages
Following is a description of the above fields:
-
name of host
-
up or down host status.
Machines for which no status report has been received for 5
minutes are shown as being down.
-
the amount of time the host has been up or down. The
time is given as days+hours:minutes.
-
the number of current users.
Users idle an hour or more are not counted unless the
-a flag is given.
-
the load average of users shown over three time periods: previous
five minutes, previous ten minutes, and previous 15 minutes
Following is an example status line.
london up 7+14:48, 1 user, load 1.20, 1.18, 1.17
Hosts are displayed in alphabetical order unless the sort
order is changed by one of the following option flags:
-l-
Sort the display of hosts by load average,
in order of highest to lowest load average.
-t-
Sort by amount of time the hosts have been up,
in order of greatest to least amount of up time.
-u-
Sort by number of users, from most to least
number of users.
-r-
Reverse sort order; reverses either the default
sort order or the order specified by one of the
other option flags.
Limitations
Each host to be listed must be running the
rwhod(ADMN)
server, which broadcasts a status packet once every 1 to 3
minutes. The local host must also be running this server
to maintain the data files. Since broadcasts do not cross
gateways, hosts on other networks will not be listed.
If rwhod was running but is not currently running, old data files
will exist.
In this situation ruptime will display information only for the
first three fields.
