Hi All,

 

I am using boost library for logger. Seems pretty good.

 

Am using boost with asynchronous sink. Hence require a close down of sink explicitly. But this is not possible when process crashes.

Since when the process crashes everything within it goes away it's inherent to asynchronous sinks to have potential to loose some of the most recent logs. I don't see anything that could be done about it.

The only way I can imagine to ensure that logs are guaranteed not to get lost  is to use synchronous sink with some fast custom backend. Your backend could, for instance, forward logs via shared memory to some other process that actually does the writing to whichever persistent storage you choose to write to.

But as far as I know there are no such off-the-shelf backends offered in Boost.Log.

Cheers,

Leon

 

Do boost have any mechanism for the same (Like handling the signals of OS and like stack dumps)?

 

What does boost prefer for unexpected termination of process where the logs will go out uncollected?

 

Could you please help me out of this?

 

Thanks and Regards
