I have the same problem even when I use the tutorial csv files.
All the coordinates are truncated after the point. It's easy to see it in the TCP output window:
a coordinate like "-79.585739043999979,34.265521039000078" becomes "-79, 34"
Is it possible that your system has a Locale other than 'English'?
Numeric values in the simulation file use ‘.’ as the decimal separator, rather than a ‘,’ as is typical in many European locales. The GeoEvent Extension will assume your server’s locale if the Language for Number Formatting parameter is unspecified in the TCP/Text input you've configured to receive the simulated data.
If this is the case, you need to specify en_US for the Language for Number Formatting parameter (see attached illustration).
Module 2 in the Introduction to GeoEvent tutorial was updated July 30th (2015) to clarify this. Please download the latest tutorial and refer to pages 29 - 31 which discusses configuring the TCP/Text input for the exercise.
Hope this information helps -
Thanks a lot, it works fine now with the "en_US" setting, but actually, FYI, my ArcGIS for Server is in english, and it's only my OS that's in french.
Furthermore, the decimal separator was already set to "." and not ","
