ruptime(1) — Commands
NAME
ruptime − Displays the status of each host on a network
SYNOPSIS
ruptime [−ar] [−l | −t | −u]
ruptime [−ar] [−l | −t | −u] [machinename]
The ruptime command displays the status of each host on a local network that is running the rwhod daemon.
If machinename is specified, only the status of that machine is displayed.
OPTIONS
−aIncludes all users. Without this option, users whose sessions are idle an hour or more are not included.
−lSorts the list by the load average over 5-, 10-, and 15-minute intervals prior to a server’s transmission. The load averages are multiplied by 10 to represent the value in decimal format.
−rReverses the sort order.
−tSorts the list by the length of uptime.
−uSorts the list by the number of users.
DESCRIPTION
The status lines are sorted by hostname unless the −l, −t, or −u option is indicated. The status information is provided in packets broadcast once every 3 minutes by each network host running rwhod. Any activity (such as the power to a host being turned on or off) that takes place between broadcasts is not reflected until the next broadcast. Hosts for which no status information is received for 11 minutes are reported as down.
