Proposed commit message
The
network.transportandnetwork.protocolfields are not being set properly. Often the transport value (udp/tcp) is getting set to the protocol field and the protocol is never set at all. The changes I made to thetest-device.log-expected.jsonfile should demonstrate these issues.I also added handling for missing protocols and added example logs for the ones I had the ability to produce.
As a side note, I am happy to convert the entire logic for handling transport/protocol to a single script processor but I figured using the built in processors is easier for maintainability.
