Failed to reproduce results of Intel Vtune analyzing example on DPDK

I'm running a DPDK process on a Linux and tried to follow the example down below to analysis core effiency. https://software.intel.com/content/www/us/en/develop/documentation/vtune-cookbook/top/methodologies/core-utilization-in-dpdk-apps.html#core-utilization-in-dpdk-apps_RX

I ran the program on Ubuntu 20.04 and copied the file back to my windows laptop due to the lack of GUI components. And I can't get the DPDK Rx Spin Time shown before. vtune results warning logs

It's because of the warning logs. or am I missing something? Any help will be grateful.

Solution

Please check that application you are profiling contains the necessary callbacks for RX and TX tracing. To enable RX burst statistic collection in VTune Profiler you need:

build DPDK with with the CONFIG_RTE_ETHDEV_RXTX_CALLBACKS and CONFIG_RTE_ETHDEV_PROFILE_WITH_VTUNE options enabled
rebuild your test application with this DPDK
run VTune I/O analysis

To check that VTune profiling is enabled ran:

nm <test_app> | grep profile_hook_rx_burst_cb
