Administrating and killing API calls

Hi. I am trialling the DreamFactory product. I set up an AWS MySQL instance and DreamFactory on my computer running OS X.

I used DreamFactory to create the APIs for a table in MySQL. Ran a test and it all worked fine. I then used CURL from the command line and kicked of JSON file import of 20,000 rows. It started the process and after 5 minutes, realising that it was running quite slow (verified by refreshing the table in MySQL AWS), I killed the CURL command line.

However, it seems to still be uploading the data as the row count on MySQL kept increasing.

Question is how do I monitor API calls i.e. currently what is actively being used, by whom (users?) and then how to kill an API call forcibly. Say there was an issue like the above.
