[Feature Request] Extended statistics support

[sbarrier]

configuration in unbound.conf :
extended-statistics: yes

this add the following metrics :

mem.total.sbrk
mem.cache.rrset
mem.cache.message
mem.mod.iterator
mem.mod.validator

Hi @sbarrier

I personally don't use extended metrics, so I'm not comfortable implementing those blindly without testing. Moreover, I'd need to know the "type" of each metric (see https://github.com/falzm/collectd-unbound/blob/master/collectd-unbound.go#L18-L32).

I suggest you fork this repository and implement the new metrics yourself – and if you want you can submit a pull request to this project.
