How to monitor c++ daemon process?

Question

I develop one daemon tcp server with boost asio, I want to know is there any daemon manager lib to monitor the process, if the server process is dead, the manager can restart it

Answer 1

You could try to use the very powerfull daemontools to manage everything. These tools allow very in grained monitoring, restarting etc.

If you don't need this power the following shell-script is often enough:

while true; do
   $PROCESS
   sleep $SLEEP_TIME
done

This takes care of restarting your system when it crashes, but there is not much to it and if you need additions you will be out of luck.
