xpeek data broadcast facility
Xpeek is a simple live data visualization service which has been
running at the NCNR since 1997. It operates on a simple client-server
paradigm in which an autonomous server listens for data packets
broadcast by instrument computers (UDP port 8080 at the present time),
assembles them into snapshots of the current dataset being collected
on the instruments, appends a timestamp to each point, and transmits
them to subscribed client GUIs which parse and plot the data.
All broadcasts begin with the instrument name followed by a colon and
end with a newline character. Elements of the broadcast (point number,
xvalues, and counts) are of the format LABEL=value and are delimited
by tabs. For all instruments, neutron counts (or other "data") are
represented in the label "DATA". The other elements could be x-values
or metadata. In the absence of other x-values, the point number (PT)
becomes the x-axis. The first broadcast of a dataset contains the word
"START" immediately following the instrument name. This first line
contains the number of datapoints (NPTS), the filename on the
instrument computer (FILE), a list of possible x-axes (VARY) delimited
by spaces, and comments associated with the dataset (the last item on
the line -- which has no label).
A sample of a set of broadcast points is shown below:
