I am sending json output files to splunk HEC using curl. But in the splunk data it is received as normal event but not in json format. There are no stamps in the logs. I tried to send with both collector and collector/raw. Tried with both manually created json source type and _json. The data is getting in to splunk but not as json format. If I use this back slash notation to all fields then I get in json format"{\"event\":\"testing\"}". Is there any work around i can do?
