Hi,

I have a network flow data which contain destination ip address, source ip address and tcp\_flag fileds. Tcp\_flag field contains different values like  
{  
"tcp\_flag":[ACK, SYN, RST]  
}

I want to configure a job which looks for source ip address that are sending only "SYN" to the destination ip address.  
So can I know what are the functions and field name (over\_field, by\_field, partition\_field) that has to configured in the detector.

Thanks.
