Example 56 with Counter

use of com.codahale.metrics.Counter in project lucene-solr by apache.

the class MetricUtils method convertMetric.

/**
   * Convert a single instance of metric into a map or flattened object.
   * @param n metric name
   * @param metric metric instance
   * @param propertyFilter limit what properties of a metric are returned
   * @param skipHistograms discard any {@link Histogram}-s and histogram parts of {@link Timer}-s.
   * @param skipAggregateValues discard internal values of {@link AggregateMetric}-s.
   * @param compact use compact representation for counters and gauges.
   * @param simple use simplified representation for complex metrics - instead of a (name, map)
   *             only the selected (name "." key, value) pairs will be produced.
   * @param consumer consumer that accepts produced objects
