ste: Space-Time Explorer
ste is a tool to explore how command-line program work. It collects PSS usage over time, process/thread spawned, and wall-time.
sudo
Since ste uses netlink process monitoring, it needs to be run with sudo.
Example
$ sudo ste clang -o hello hello.c
EXEC: [clang /home/leaf/hello.cc]
EXEC: [/usr/lib/llvm-14/bin/clang -cc1 ...]
EXEC: [/usr/bin/ld ...]
Num threads = 3
Num process = 3
Max PSS: 127,156,224 bytes
Walltime: 221ms - user-space: 136ms - kernel-space: 69ms
