All Good.

Did you remember to restart Nagios after making the config changes?

Testing as the user the script is running as should be done anyway.
Often times it shows other, less obvious issues like required libraries
not being readable or executable by that user. I'd also suggest
simplifying things greatly by making your event handler  --

command_line    /bin/echo "$HOSTNAME$ $HOSTSTATE$" > /tmp/testing

Just to make sure that it's getting run (I'm 99% sure that'll work as I
expect ;) ).
