GRID-MONITOR(1)GRID-MONITOR(1)NAME
monitor - graphical display for viewing resource use.
SYNOPSIS
command | grid/srv/monitor interface [ wintitle ]
DESCRIPTION
Monitor is designed to work with resources that deal with incoming con‐
nections (such as grid-register(1)) to visually display the connections
to a specific resource. 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 inter‐
face 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. Wintitle optionally sets the title
of the monitor window. Command must write status messages to stdout
which are then read and displayed (if appropriate) by monitor. Monitor
reads on stdin and accepts the following input:
Interface 1
add addr display a connection from address addr
del addr remove a connection from address addr
Interface 2
data set id { data } set and display the string data in slot
id.
data set id finished clear slot id
