ntop 3.3.10rc1 (Development branch)
01-16-2009
ntop is a network probe that shows network usage in a way similar to what top does for processes. In interactive mode, it displays the network status on the user's terminal. In Web mode, it acts as a Web server, creating an HTML dump of the network status. It sports a NetFlow/sFlow emitter/collector, an HTTP-based client interface for creating ntop-centric monitoring applications, and RRD for persistently storing traffic statistics.

ruptime(1) General Commands Manual ruptime(1) 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
Includes all users. Without this option, users whose sessions are idle an hour or more are not included. Sorts the list by the load aver- age 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. Reverses the sort order. Sorts the list by the length of uptime. Sorts 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 broad- cast 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. EXAMPLES
To get a status report on the hosts on the local network, enter: $ ruptime Information similar to the following is displayed: host1 up 5:15, 4 users, load 0.09, 0.04, 0.04 host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 (Output may be formatted differently on your system.) To get a status report sorted by load average, enter: $ ruptime -l Information similar to the following is displayed: host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host1 up 5:18, 4 users, load 0.07, 0.07, 0.04 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 (Output may be formatted differently on your system.)
