I did a test with a successful post and some other requests that is all successful in the plugin,and check out the data in the table,their HTTP_STATUS_CODE column's value were all logged null.
Checked all records in the table,the column value is right(307,404,401...) if the had bad request,and for some successful request ,the column's value is 0.
So I think maybe the HTTP_STATUS_CODE value should be 200 instead of 0 or null if the request is successful?
