<p>You can collect Pulsar broker metrics from brokers and export the metrics in JSON format. The Pulsar broker metrics mainly have two types:</p>
<ul>
<li><p><em>Destination dumps</em>, which contain stats for each individual topic. You can fetch the destination dumps using the command below:</p>
<pre><code class="hljs css language-shell">bin/pulsar-admin broker-stats destinations
</code></pre></li>
<li><p>Broker metrics, which contain the broker information and topics stats aggregated at namespace level. You can fetch the broker metrics by using the following command:</p>
<pre><code class="hljs css language-shell">bin/pulsar-admin broker-stats monitoring-metrics
</code></pre></li>
</ul>
<p>All the message rates are updated every minute.</p>
<p>The aggregated broker metrics are also exposed in the <a href="https://prometheus.io">Prometheus</a> format at:</p>
<pre><code class="hljs css language-shell">http://$BROKER_ADDRESS:8080/metrics/
</code></pre>

<p>You can configure the stats frameworks for BookKeeper by modifying the <code>statsProviderClass</code> in the <code>conf/bookkeeper.conf</code> file.</p>
<p>The default BookKeeper configuration enables the Prometheus exporter. The configuration is included with Pulsar distribution.</p>
<pre><code class="hljs css language-shell">http://$BOOKIE_ADDRESS:8000/metrics

<p>You can use Prometheus to collect all the metrics exposed for Pulsar components and set up <a href="https://grafana.com/">Grafana</a> dashboards to display the metrics and monitor your Pulsar cluster. For details, refer to <a href="https://prometheus.io/docs/introduction/getting_started/">Prometheus guide</a>.</p>
<p>When you run Pulsar on bare metal, you can provide the list of nodes to be probed. When you deploy Pulsar in a Kubernetes cluster, the monitoring is setup automatically. For details, refer to <a href="/docs/en/next/helm-deploy">Kubernetes instructions</a>.</p>
