Hi.

At least your forwarding of your own mail made it readable (i.e. less 
html formatting).

You _do_ know that this is not the support line for paying customers?

Right. Read up on check_intervals and check_attempts. That _might_ have 
something to do with your problem.

By the way: What does "show" in your paragpraph above mean? Do you mean 
the web interface, or the notifications?

The percentage is calculated like ... well, like you calculate 
percentages. Someting like 100*(sent-returned)/sent is what I'd guess. 
If you need to know better you can read the sourcecode. I doubt anyone 
will explain the inner workings of the plugins to you - you asked your 
questions often enough, and to me it seems as though you should be able 
to find out what you want by simply using the documentation coming with 
the software.

If you need help undertandning the manual you should ask people around 
you, because on a mailing list it's sort of dificult to discuss one's 
undertanding of the documentation. If you don't have the time to use the 
manual you should pay somebody to setup nagios according to your needs.

By the way: The number of tries is determined by the command line 
options you give the plugin. You _should_ try check_<insert generic 
plugin check command name here> -h and try to understand the output. 
Doing some trying on the command line doesn't hurt either.
