> Programs can and will exit before the userspace daemon is able to read from /proc that's depend on the use case, and we are mainly tracking server which are not terminated during our runtime. of course if we are tracking "not servers" (like curl) it can happen, and for that you can find other fallbacks. regardless, we cannot assume we will be existing before all other server and client have started running, so we are trying to do "best effort", that's why counting on hooking the `exec` syscalls is not robust either.

If best effort is good enough and your use case doesn't require robustness, reading out of host /proc certainly works. Tracking execs with hooks in the kernel's internal exec mechanism with a separate indexing step at startup is worth the extra effort for use cases that do require accurate data, such as security observability.
