rup displays a summary of the current system status of a particular host or all hosts on the local network. The output shows the current time of day, how long the system has been up, and the load averages. The load average numbers give the number of jobs in the run queue averaged over 1, 5 and 15 minutes.
The rpc.rstatd(8) daemon must be running on the remote host for this command to work. rup uses an RPC protocol defined in /usr/include/rpcsvc/rstat.x.
