1 month ago Hi there,
The good news is that your input URI is correct, but that error suggests that libtrace was not compiled with DPDK support.
Just so I can get an exact picture of what is going on, can you please tell me:
- what operating system / distribution you are using?
- is DPDK installed via a package manager or have you built it from source using meson?
- what version of DPDK are you using?
- what is the output when you run
./configureduring the libtrace compile process (specifically, the output at the end where it says what build options have been chosen) ?

hi,
i have bind an interface to dpdk. root@EM-GBDF0H2:usertools$ ./dpdk-devbind.py --status

meanwhile, i also follow "Compiling Libtrace with against a local copy of DPDK" to install libtrace. when i use tracepktdump command to capture packets of 0000:04:00.1. i don't know the inputuri.
i tried like blow, but it doesn't work. root@EM-GBDF0H2:usertools$ tracepktdump -f "port 8019" -c 10 dpdk:0000:04:00.1 trace_create: Unknown format (dpdk)
Any ideas are appreciated!
