This probably happens because echo adds a trailing newline character and
NSCA-ng's send_nsca interprets that as another check result (because
it's seperated from the previous result with an ETB character). The
following commit lets send_nsca ignore such trailing newlines:
https://www.nsca-ng.org/cgi-bin/repository/nsca-ng/commit/?id=521c7d15
However, using "echo -n -e [...]" should do the trick.
