BookKeeper enables metrics collection through a variety of stats providers.
For a full listing of available metrics, see the Metrics reference doc.
BookKeeper has stats provider implementations for four five sinks:

| Finagle | org.apache.bookkeeper.stats.FinagleStatsProvider |
| Ostrich | org.apache.bookkeeper.stats.OstrichProvider |
| Twitter Science Provider | org.apache.bookkeeper.stats.TwitterStatsProvider |
The [Codahale Metrics]({{ site.github_master }}/bookkeeper-stats-providers/codahale-metrics-provider) stats provider is the default provider.
