Packetbeat analyzes specific protocols and is not suitable for full capture of all network traffic and network flows. I recall that Packetbeat can cover a limited number of protocols including ICMP, but not as deeply as other solutions. It covers NetFlows and these types of flows, but not at the level of a deep packet capture that you can find in the market where it taps every single packet in the network. Packetbeat is more about bringing statistics about the packets, but it doesn't capture these packets. The development intention of Packetbeat appears to be to provide a window for application monitoring and performance analytics, and for that purpose, it is doing sufficiently well. However, if the vendor has another goal to build a similar network monitoring solution that exists in the market, which is outside of Elastic's business nature, Packetbeat is a sensor that needs to be improved to the level of deep packet capture where it loses no packets in the network. That improvement would take Elastic to another level.
