Hi List,
I'm looking for any mechanism in a multi-threaded process to monitor the
health of its running threads - or by a specific monitor thread or by
any other mechanism.
It includes the following aspects:
1) Threads are running and not stuck on any lock.
If you're using posix locking, you'll never find yourself busy-waiting for very
long. Use ps or top.
2) Threads are running and have not died accidentally.
Use ps or top.
3) Threads are not consuming "too much" CPU/Memory.
Use ps or top. You'll have to decide how much is "too much".
4) Threads are not in any infinite loop.
This requires solving the Halting Problem. If your management is demanding this
feature, I suggest informing them that it is mathematically impossible.
Just use top or ps. Don't reinvent the wheel. We've got a really good wheel.
If you don't like top or ps as is, read the ps man page to see all the fancy
formatting it can do, and parse it with a simple script in your favorite
scripting language.
