[Unbound-users] unbound and hobbit / xymon

[Dmitriy Demidov]

Hi Gabriel.

Some extra hints to you (I just remember about them).

First hint - unbound-control stats for many of it's output variables produce 
statistics in dynamic way. For example - if you server didn't have queues for 
A type records then `unbound-control stats` output will not contains any 
string for num.query.type.A=. And by default, then this dynamical variables 
are queued (then `unbound-control stats` command is executed) they are 
cleared from output again. 
So, if hobbit expects that some variable always *should* be in output  - you 
should take this behavior in account.

Second hint - if you wanna to implement historgam graph in hobbit you should 
think how to merge output from histogram.000000.000000.to.000000.000000 type 
variables because there is so many of them...

This two problems can be fixed by using script what will do parsing of 
`unbound-control output`. Take a look at this archive:
http://unbound.nlnetlabs.nl/svn/trunk/contrib/unbound_cacti.tar.gz

Archive contains unbound_cacti parsing script. I think it would be quite easy 
to adopt it for hobbit.

Good luck.
