You might want to check out NSCA-ng. We transitioned to that and it's been doing well in our environment. https://www.nsca-ng.org/

Is it worth considering some NSCA > replacement? I've tried to patch the NSCA code when I was working in Vienna, but it wasn't much fun. The idea is good, the implementation is pure mess. I've seen that nsca-ng works well, but requires different security and therefore sending clients. Apart from that, another user approached us with an nsca interface as neb broker module for 1.x, called "icinga-iris". I've incorporated several patches sent into the 1.13 tree, which is yet to be released (try the snapshot packages from packages.icinga.org) I wouldn't bet much on NSCA these days, that's a dead end.
