Thoughts about a custom plugin

[Paulus, Jake]

In Nagios 2 there is a limit to plugin output measured in Bytes (forget
the number) - it amounts to about 252 characters before the output is
truncated. Nagios 3 fixes this potential problem. I'm pretty sure the
original intent was as a security or performance precaution...but there
are definitely cases where longer output is needed. The guideline is
still a very good one though. Output as shown below is great to parse
for graphing - but our admins don't like looking through it to find the
actual problem (notice the output is truncated too)

Sorry for the 8, it was supposed to be 80, and came from a web page I
read
about developing NAGIO plugins. If I recall the reason corectly, it was
because that status might go to a printed report?
