send_nsca

[Hari Sekhon]

Hi Tony,

   That's a very good point. It wouldn't be difficult to make this 
support multiple simultaneous checks, but I currently have the checks 
running independently of one another and it works very well.

This was originally written with the intent to make it easy to take any 
single check and turn it passive without re-creating the wheel, simply 
by putting this script in front of it.

If you grouped checks then this implies that they must all be run at the 
same time, which seems to reduce flexibility.

Also, I think that for a lot of passive service checks it is advisable 
to not have them run at the same time. For example, I have check running 
at different intervals intentionally for staggering on the servers so 
that there is no performance degradation on the server performing the 
passive checks, although this could simply be one after the other which 
also should reduce performance in comparison, but watch out for multiple 
long running checks as this will may send the check result beyond the 
freshness threshold.

If anyone really wants this feature I may look in to incorporating it, 
but I haven't seen any need for this "optimization" which would probably 
make very little difference until we start talking a massive number of 
passive service checks.

I am open to ideas on this though.
