what we are going to do here is look at
how to set up and configure the window
transformation agent
this agent allows for data to buffer for
an allocated amount of time before it is
pushed further along the stream
i already have an event simulator agent
setup and configured
which will simulate the number of
readings coming from sensors
i also have an event printer agent setup
which will help us see what the data
looks like when we are running our
stream
go to the toolbox and search for window
you will find it under transformations
click on the agent and drag it to the
canvas
connect the output endpoint of the event
simulator agent to the input endpoint of
the window agent
and the output endpoint of the window
agent to the input endpoint of the event
printer agent
note that a default name has been
assigned to your window agent
to rename this agent click on the white
space and start typing
click somewhere else on the canvas and
click save
double click on your window agent
this is where you will be configuring
your agent
first make sure you're using the correct
collection
if not select another collection from
the drop-down
next you need to configure your window
from the drop-down select the time unit
you'd like to use
i would like to buffer my data for five
seconds so i'm going to select second
and go i'm going to set the size to five
click apply click save
now i want to run my stream for that i'm
going to click on publish
to view the live data click on live view
and select your event printer agent and
click save
give it a second
and you'll see that i start coming
through to expand the page click on
maximize
