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.
2) Threads are running and have not died accidentally.
3) Threads are not consuming "too much" CPU/Memory.
4) Threads are not in any infinite loop.
My questions:
1. Which kernel APIs can help here?
2. Which kernel APIs can supply CPU/Memory information on a given thread
ID?
3. Is there any non-intrusive mechanism to achieve those goals?
I found that in kernel 2.6:
Reading the content of /proc/process_id/task_id/ can supply some
information per running thread in a given process.
Is it a recommended way to go with?
What about kernel 2.4 as this information doesn't exist per thread?
My questions relates to Kernel 2.4 and also to newer (e.g. 2.6) Kernel
versions.
Any help will be appreciated.
Thanks,
Yishai.
