  '/chart'
end

#metrics_under(path, cursor = nil, limit = 100) ⇒ Wavefront::Response

Gets a list of metrics under the given path. This must be done via recursive calls to the API, so calls can take a while. If you ask for all your metrics, expect to be waiting some time.

def metrics_under(path, cursor = nil, limit = 100)
  resp = api.get('metrics/all',
                 { trie: true, q: path, p: cursor, l: limit }.compact)

  return resp unless resp.ok?

  metrics = resp.response.items

  metrics.each do |m|
    if m.end_with?('.')
      metrics += metrics_under(m).response.items
      metrics.delete(m)
    end
  end

  # resp.more_items? doesn't work: we don't get that from this API

  if metrics.size == limit
    metrics += metrics_under(path, metrics.last, limit).response.items
  end

  resp.response.items = metrics.sort
  resp
end

#response_shim(resp, status) ⇒ Object

We have to try to make the response we get from the API look like the one we get from the public API. To begin with, it’s nothing like it.

This method must be public because a #respond_to? looks for it.
