What is the current standard for graphite frontends? There are so many, it's hard to know where to aim. We're in the process of setting up a few metric collection systems for evaluation, and setting up the right frontend for graphite is a hard choice.

I used grafana and tessera and I prefer tessera. I like the different data types it can support. Its not as user friendly as grafana

Depends on your context and problem you are solving (size, complexity) but I think the default became Grafana.

Rickshaw works quite nicely (you have to the plumbing to render the graphs)

Grafana seems to be the most extensive in terms of features

That's the conclusion I've come to also, thanks.
