New Packetbeat Protocol - accessing lower layer Info

(David Hughes) #1

We've created our own UDP protocol in Packetbeat.

We're successfully accessed the payload past UDP using the Payload field within the Packet struct. We see the tuple information as well for IP.

What we're wondering however is how can we access other lower layer information from IP (TTL), or Ethernet (VLAN ID, MAC addresses), etc. Is that possible? If not, is there at least a way to get the entire packet payload (not just past UDP), so that we could parse this ourselves?

Thanks in advance,

Unfortunately, full packet information is not available to protocol processors. As making this information available requires a significant refactor to Packetbeat. Feel free to create an Enhancement request, or experiment with propagating this information yourself, from the Decoder in decoder.go to the UDP protocol processor.
