Compendium: A Linux Syscall Tracer
Having a love-hate relationship with strace I ended up yearning for something new.
Enter Compendium: a friendlier strace-like tool, with sane defaults, that optionally produces a clean html report that you can view in your browser of choice.
It tracks file descriptors across their lifetime, distinguishes files from sockets, aggregates I/O stats, registers events for memory operations (both vm and actual page faults), threads/subprocesses and more in real time and produces a summary at the end.
