Go to https://xmpro.com... what we are going to do here is look at
how to set up and configure the filter
transformation agent
this agent allows for incoming data to
be filtered according to the conditions
defined by a user i have already set up
and configured
an event simulator agent which will
simulate temperature readings from a
sensor
i am only interested in readings higher
than 50 degrees celsius
anything lower than that should be
disregarded
i have also added an event printer to
the canvas
which will allow us to see what the
filter data looks like
go to the toolbox and search for filter
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 filter
note that the filter has two other
endpoints
the output endpoint is for when the
condition specified holds true
the false endpoint is for when the
conditions specified does not hold true
you are only required to connect the
output endpoint to another agent
so i'm going to go ahead and connect the
output endpoint of the filter agent to
the input endpoint of the event printer
agent
also note that a default name has been
assigned to the filter agent
you can rename this agent by clicking on
the white space and start typing
click somewhere else on the canvas and
click save
double click on your agent
this is where you will be configuring
your filter
first make sure you're using the correct
collection
if not select another collection from
the drop down
next i want to configure my filter note
that the default group has already been
added for you
to add a condition click on the plus and
click on add condition
next select the field you want to apply
the filter to
which in our case is temperature
select your equation i'm going to select
is greater than
and then i'm going to add my value which
is 50.
click apply click
save now i want to run my stream so i'm
going to click on publish
to view the live data click on live view
and select your event printer
click save
now that the data coming through is all
above 50 degrees
