[Nagios-users] Dual call to NEB callback functions. (help)

[Ethan Galstad]

This isn't a bug, but it is confusing, especially since I haven't 
started on the NEB documentation yet.  For active checks, you should 
be getting two callbacks for each check.  For passive checks, you get 
only one.

The key is to check the .type member of the data structure that is 
passed to the callback function.

If type==NEBTYPE_SERVICECHECK_INITIATE, the service check has just 
been initated (only for active checks).  This event is usually only 
useful if you want to track when a service checks gets executed.

If type==NEBTYPE_SERVICECHECK_PROCESSED, the data contains the 
processed results of the service check.  This is probably what you're 
interested in. 

Hope that helps.
