Rewriting nsclient? (was NSClient 1.0.8.0 Installation Problem)

[Michael.Wirtgen at miwi-dv.com]

All,

I'm currently working to get nrpe "ported" to run on windows, so I take a
great interest in this.

Please allow some thoughts & questions...

- If you consider rewriting nsclient to add nrpe functionality, what do you
consider the benefit? 
May be I'm missing something, but to me it looks like a decision between
monolithic vs. modular design. Whatever you choose may be ok, but I see no
reason in mixing this? 
If you go with the current nsclient design, I'd suggest, ALL checks should
be done by the agent. However, this would make this a very complex beast,
and it may be difficult to add new checks. If you go with plugins, why not
put everything into a plugin? Is there anything that would be impossible to
implement as a plugin? (Thinking of it, registering callbacks on eventlog or
filesystem events pops to my mind ...)

- On choosing a development language, perl sounds great in terms of porting,
but I think for windows, the only option for any agent is to run as a
service. On my boxes I usually prefer NOT to resort to any wrappers to
achieve this. For everything else, I guess the answer is: Whatever gets the
job done.... 

- Tim, I can't resist to ask this ;-)
>>Hell will freeze over before I buy a product from MS
What do you actually RUN nsclient on?

cheers
MiWi

It is a pretty good idea to start a rewrite of the NSClient and add in
the nrpe functionality, also make this an agent that will work on
virtually every OS available, at least the OS's that nagios and the
current nsclient runs on.  I myself would find that an agent such as
nslcient would be more appealing to get simple stats such as disk space,
uptime, and memory from servers.  Being perl, I don't know, would
probably work on most systems, but of course, windows admins probably
would want a binary.

Creating a Nagios agent though would be sweet and extend the software
package just that much further.  

(even more to think about is building into the agent IDS software, and
let it send nagios security alerts, that would be cool, a single tool
for security and availability!)

FWIW, there's always FireDaemon for turning binaries into a service:
