Puppet users - May 2008 - Puppet ramblings: use the beast to monitor hosts

Ok, take this post as a half-serious, just an (old?) idea or whatever.

Facts:
- An host is polled or polls more or less regularly its master.
- It provides arbitrary local info via facts
- It can provide feedback to a central location in various ways (mail,
log, rrd... )

Under some points of view puppet is also an indirect IDS (it detects
certain file changes).
Under some points of view puppet is also a service checker&manager (it
restarts crashed services).

Under some points of view puppet can be tweaked into a monitoring
system.

Right now it can do much of the work (checks and some kind of
notification service) with custom facts and some engineering, it just
misses a sort of (web based?) dashboard to view what is happening.

Now,
- I know there are already good tools to monitor everything
- I know this is not supposed to be Puppet''s goal

but I still find the idea somehow intriguing.
Anyone else?

That''s a good idea,now ,I use external resource and nagios to monitor
host,but when the client more and more,it''s not so good, and  need add
DB server.that''s let the structure be complex. I''m looking for
a
stupid and simple solution.

I want still use nagios to monitor host,but I don''t want use the
puppet''s external resource, I don''t know there have another
method to
let the nagios auto monitor the new host that  join the puppet fram
and not use the external resource.

may I ask why you''d like to avoid external resources? They''re
the
easiest way to solve this problem.

choice at this time :D
