Thanks for the quick reply Henrik!
I really think that the bigger problem is, as you said, the correctdaily-basics knowledge to develop a good-and-well-structured database for Hobbit, which is a biiig project.
The availability problem is actually not a problem, you can create aCluster/Replication for the Database in the case of big structures, for small environments you can just deploy the database on the same server, i think its like 95% of environments todays that uses Hobbit/Xymon btw...
I have a work colleage whos have basic/good knowledge developingC/database applications, maybe in a near future we can dedicate the aproppriate time to code a such an addon as you said, i'll keep in touch if i have any news...
For now, thank you very much for your great effort.
Regards,Giovanni

Hi Henrik,
I was reading about 4.5 release and maybe its time to think about
store
the data into a Database like MySQL/PostgreSQL, if you do that far more contributors can start to colaborate with customs web-interfaces, reports, etc etc.
this subject comes up once in a while. I have two problems with it:
I've never done any programming that interfaces to a database, so it would mean digging into one more API - but that is something I could probably handle.
The real problem is that unless the database is co-located with the Xymon server, then your monitoring suddenly becomes dependant on a remote database-server. So what happens if your database server loses the network connection to the Xymon server ? You won't get any alerts from Xymon, because it has no data available to generate alerts from.
It's the same reason that has kept me from using SAN storage for my production Xymon server at work. Much too complex for my taste, far too many ways it can break.
And the time when you need your Xymon server the most is *exactly* when everything else has gone down in flames.
What I *would* consider is to create a module like the hobbitd_filestore module, except it sends the status-data off to a database somewhere. Or even an external module for hobbitd_rrd that gets all of the parsed data we collect and use as the basis of all of the graphs. Such modules would be very easy to write for someone who knows how to do programming with the database API - my guess is that it wouldn't take more than a day or two.
So if you know someone who could voluteer for such an add-on, I would be very happy to work together with him/her on putting such an add-on together.
