If you have source code access to the kernel and know the functions that you would like to monitor, you can use kprobes. You'd have to write a kernel module and attach to the function that you wish to debug. Since it's a kernel module, you'd have to be careful about semantics. http://lwn.net/Articles/132196/ tcpprobe is a wonderful example that uses kprobes. http://www.linuxfoundation.org/collaborate/workgroups/networking/tcpprobe Its source code is here: /path/to/linux-$(uname -r)/net/ipv4/tcp_probe.c Good luck, -- Vimal -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
