The tail_csv plugin does that, but unfortunately it has the comma
character as the separator hardcoded. Modifying the plugin to use tab
should be pretty straightforward though. Bonus points for making this
character configurable and sharing the patch ;-)

For summing fields, assuming you base on tail_csv for metrics
collection, you can imagine using the aggregation plugin.
