One area where Linux is deficient is semaphore and mutex performance monitoring. Solaris and AIX have lockstat, which is very useful when doing driver development, benchmarking, and database tuning.

I am aware of SGI lockmeter, which requires a kernel patch and SystemTap, which lets me roll my own script, after I install it and rebuild the kernel.

Is there anything more mainstream for this type of performance monitoring on Linux?
