Hi,
I am currently developing a module in Apache 2.4.4
I need a counter that is going to count all requests in the system and based on a small processing, some of them are to be tagged and counted separately. I would like to do this the right way, in memory and not using shared file on the hard disk.
At this point I can have a thread-safe counter per worker but I want to save it periodically into a DB. I was looking for some kind of timer-based event or something, or something like idle-event hook or anything (whatchdog would be my last idea) to be able to save periodically these counters into a DB.
Another way I found is working with shared memory like this example does:
but I have a doubt that the shared memory is actually a file on disk and for each counter incrementation the hard disk is accessed.
Please help me getting on the right track. Thank you.
