Re: [hobbit] Xymon 4.3.0: Beta version available on Sourceforge

How about you alert on the incoming as usual, then store the events (batched
or not) into the backend database so that reports can be developed for
management, history could use for lookups, etc... That might make this a
little more palatable to you, and a lot more usable to those of us who have
to prove to management that the  time we invest in getting this doing what
we want is not a drain on their resources. 

Reports are management blood, no reports - no use... (for managers) - I have
had managers tell me this in the past. (on the other hand - two weeks after
I installed clients on one department's sun servers, the manager had some
questions about server performance over the past few weeks = was quite
pleased and surprised when I gave him a spreadsheet that laid out the data
for all his servers in 1/2 hour, as was even more please when I showed him
how to view his page of servers.)

Another thing that using a database to store history in - much better
security for those of us who work in security realms and have to protect
data - alarm history can give a lot of info away to a hacker if they gain
access to the server running the master.
With a database, it can be secured and only have authorized users that
access it.

One thing everyone should remember - in business, as in life, perception is
80 % of the way things are seen - think about it...

this subject comes up once in a while. I have two problems with it:
 
 
1) 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.
 
2) 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.
 
 
Regards,
Henrik
