I had turn on apm.use_dns and it seem that it dosen't resolve those ip address to name based on the local host file. Is there a way to enable CAS to resolve those ip address from netflow source to hostname ?
Resolving IP addresses for netflow traffic is currently supported. What local host file do you have in mind? You may test resolving IP addresses in CAS by executing RESOLVE IP diagnostic command.
Note you may also define static mapping in dns_map-hcbs.properties
