Tommaso Teofili commented on OAK-7839:
--------------------------------------

> I wonder if a {{Counter}} meter might be better which you increment on

I think that depends a bit on what we want to take out of the metric, for 
example if we want to take availability percentiles into account, I would say 
that points in time when index is not available is enough, of course also a 
counter could work, but wouldn't have to be decremented (I think).

> In order to integrate with more metrics tools , we can evaluate exposing some 
> indexing related metrics as Sling Metrics / DropWizard metrics.
> This taks is just for the sake of evaluation and possible integration points.
