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.

Cheers
Sunil
