.SH NAME
monitor \- graphical display for viewing resource use.
.SH SYNOPSIS
.I command
.B | grid/srv/monitor
.I interface
.B [
.I wintitle
.B ]
.SH DESCRIPTION
.I Monitor
is designed to work with resources that deal with incoming connections (such as
.IR grid-register (1))
to visually display the connections to a specific resource.
.I Interface
sets the style of interface, this can be 1 or 2. Interface 1 is the simplest, displaying only a list of connections to the resource. Interface 2 is slightly more complex, allowing extra data to be displayed for each connection. While interface 1 shows all the connections at any one time, interface 2 displays a selection of 'slots' which have buttons that light up to signify a connection. Clicking on a lit button will display any data given about that connection in the main window.
.I Wintitle
optionally sets the title of the
.I monitor
window.
.I Command
must write status messages to
.I stdout
which are then read and displayed (if appropriate) by
.IR monitor .

reads on
.I stdin
and accepts the following input:
