Nagios limitation on size of PLUGINOUPUT.

[Stanley Hopcroft]

Dear Sir,

I am writing to supplement Mr De Bisschops answer about this and say,

> From: Brian Rectanus <Brian.Rectanus at vt.edu>
> To: nagios-users at lists.sourceforge.net

> It seems that only a single line of output is read from the plugin.  
> This seems very limiting to me.

and so it did to me once upon a time.

However, the people who get alerted by Nagios at this site do _not_
want or expect Nag to diagnose the problem for them.

All they want is to be alerted to 

. the problems existance

. the rough location of the problem (in 'this' service for example).

and then they dive in and use the problem solving techniques that work 
best for them.

So while I ran Netsaint and Nag for a while with a local patch that 
would read the plugin ouput to eof (very trivial patch to checks.c), I 
no longer think it worthwhile to maintain the patch and the risk of it's 
side effects.

So, while such a patch is feasable and easy, however as Mr De Bisschop
has noted, it is best left as an option because of the performance hit.

Nagios performance (being able to poll vast numbers of services in a
timely manner) is probably more important to most Nag users than the
amount of fault information it returns.

But don't listen to someone who is not the Nagios developer: send your
patch to Nagios-devel.

Yours sincerely.
