NAME

       sinfo - a monitoring tool for networked computers

SYNOPSIS

       sinfo  [-q]  [-V]  [-W]  [-H]  [-L] [-h host[:port] ] [-u user ] [-d delay ] [-s] [-o] [-i
       process ] [-n] [-D] [-t count ] [-i processname ] [-c scale ]

DESCRIPTION

       sinfo displays some information of the nodes in your local network.   For  each  node  the
       system load, the memory utilization and the `TOP-5' user processes will be displayed.

       sinfo  uses  the  sinfod(8)  to  gather  these  informations.   For further details of the
       internal mechanisms refer to the sinfod(8) manual.

OPTIONS

       -q/--quiet
              be quiet - don't display startup informations.

       -V/--version
              Print the version number and exit.

       -W/--wwwmode
              Web-mode: List all hosts and their informations in html-format and exit.   Look  at
              sinfo.pl.cgi for a sample cgi-script.

       -H/--hostsmode
              List all host names of nodes running a sinfod(8) and exit.

       -I/--ipmode
              List all IPs of nodes running a sinfod(8) and exit.

       --hostsandipmode
              List all host names and IP addresses of nodes running a sinfod(8) and exit.

       -L/--loadmode
              List all known host names with the current system load and exit.

       -h/--host <host[:port]>
              Fetch  information  from the sinfod(8) running on `host' instead of localhost.  You
              may also specify the port number of the sinfod(8) your  are  connecting  to.   This
              option  may  be useful in cases where ssh(1) or similar programs are used to tunnel
              the connection from sinfo(1) to sinfod(8) through a firewall.  It  is  possible  to
              use  multiple -h option to connect to more than one sinfod to monitor more than one
              network with one sinfo process.  If your want  to  set  different  delays  for  the
              connections -d has to be specified prior to the corresponding -h options.

              $ sinfo -h localhost:60001
              (the default values)

              $ sinfo -h 127.0.0.1:60001
              (... if you want to set an IP-address directly)

              $ sinfo -h my.computer.at.work
              (port 60001 will be used as default on my.computer.at.work)

              $ ssh -q -C me@my.computer.at.work -L 60002:my.computer.at.work:60001
              (establish the tunnel)
              $ sinfo -h localhost:60002
              (connect through the tunnel)

              $ sinfo -h localhost -h host.on.another.net
              (connect two demons to join the sinfo broadcasts of two networks)

       --udp / --tcp
              Use UDP(default) or TCP to connect to sinfod.

       -u/--user <user>
              Highlight all processes of `user' instead of using environment variable $LOGNAME.

       -d/--delay <delay>
              Set the delay (in seconds) between two updates.  Default is one second.

       --filtermarker <marker>
              Request only informations matching <marker>.

       -s/--systeminfo
              Include system information (resolved by a uname -a call) in the list.

       -o/--own
              Only  display  your  own  processes  or the processes owned by user '-u user' (this
              overrides the '-t count' setting).

       -i/--ignore <process>
              Don't display <process> ; --ignore may be set multiple times.

       -n/--netload
              Display network load.

       -D/--diskload
              Display disk load (buffer allocation rate) of locally connected disks.

       -t/--top <count>
              Restrict the number of processes displayed to `count'.

       -c/--scale <scale>
              Set the scaling of the CPU load bars to "log", "lin" or "full".

KEYBOARD COMMANDS

       PageUp, PageDown
              Scroll the screen by one page.

       UpArrow, u; DownArrow, d
              Scroll the screen by one line.

       Home   Jump to the top line.

       s      Toggle display of system informations.

       o      Toggle display of your own processes.

       n      Toggle display of network informations.

       D      Toggle display of disk load.

       t      Toggle display of the TOP n processes.

       c      Toggle the scaling of the CPU load bars form "log", "lin" to full.

EXIT CODES

       The exit codes used by sinfo are:

       0      everything OK

       1      Connection to sinfod failed.
