Histograms

Creating

Create your histogram:

(use '[metrics.histograms :only (histogram)])

(def search-results-returned
  (histogram "search-results-returned"))

You can create a biased histogram by passing an extra boolean argument:

(def search-results-returned-biased
  (histogram "search-results-returned-biased" true))

Reading

Writing

Update the histogram when you have a new value to record:

(use '[metrics.histograms :only (update!)])

(update! search-results-returned 10)
