Faster, high-performance NSCA server with worker and threadpool support. Drop-in replacement.
Faster, high-performance NSCA server with worker and threadpool support. Drop-in replacement.

new options:
decryption_mode=1 # default is 1, this is faster. 0 is more secure
nsca_workers=4
nsca_threads_per_worker=8
max_checks_per_connection=5000
max_packet_age_enabled=0 # by default packet age check is disabled in the original nsca server even if you set max_packet_age. I keep it that way, but you can override nagios core behaviour by settings this value=1. I dont think its a good idea if the NTP sync is disabled on the clients.


As you can see it could use fix workers (fork) with the kernel's REUSEPORT support.
You can use fix size thread pools in workers. So you wont end up with infinite workers and infinite thread pools.
It supports fifo and check_result_path at the same time if you set both. First it writes the result into fifo and if it fails it saves it in the check_result_path
