virtual machine - VirtualBox Ubuntu 18.04 VM does not have tcp_probe

asked Oct 7, 2021 in Technique[技术] by 深蓝 (71.8m points)

I need to use tcp_probe for monitoring the congestion window on by Ubuntu 18.04 VM on Virtual box. On my host system, I am able to find /sys/kernel/debug/tracing/events/tcp/tcp_probe but the Guest OS does not have a tcp_probe file under the tcp folder in the path above. How can I fix this, as I need tcp_probe with perftools?
