- <div class="row">
- <div class="col-md-6">
- <h4>Server-side programming</h4>
- <p>Accumulo has a programing meachinism (called <a
href="/docs/2.x/development/iterators">Iterators</a>) that can modify key/value
pairs at various points in the data management process.</p>
- </div>
- <div class="col-md-6">
- <h4>Cell-based access control</h4>
- <p>Every Accumulo key/value pair has its own <a
href="/docs/2.x/security/authorizations#security-labels">security label</a>
which limits query results based off user authorizations.</p>
- </div>
- </div>
- <div class="row">
- <div class="col-md-6">
- <h4>Designed to scale</h4>
- <p>Accumulo runs on a cluster using <a
href="/docs/2.x/administration/multivolume">one or more HDFS instances</a>.
Nodes can be added or removed as the amount of data stored in Accumulo
changes.</p>
- </div>
- <div class="col-md-6">
- <h4>Stable</h4>
- <p>Accumulo has a stable <a href="/latest/apidocs">client API</a> that
follows <a href="https://semver.org";>semantic versioning</a>. Each Accumulo
release goes through <a
href="/docs/2.x/getting-started/features#testing">extensive testing</a>.</p>

- <title>View Accumulo metrics in Grafana</title>
- <description><p>The <a
href="/features/#screenshots">Accumulo monitor</a> provides
the easiest way to view Accumulo metrics but it has two limitations:</p>
-
-<ol>
- <li>The overview page is limited to 10 graphs</li>
- <li>These graphs only show metrics for the past two hours</li>
-</ol>
-
-<p>The Accumulo monitor could be improved to be better a visualization
tool for metrics but this doesn’t make
-sense when tools like <a
href="http://grafana.org/">Grafana</a>, <a
href="https://graphiteapp.org/">Graphite</a>, and <a
href="http://ganglia.sourceforge.net/">Ganglia</a> exist and
Accumulo can report metrics to these tools
-using <a
href="/docs/2.x/administration/monitoring-metrics#hadoop-metrics2">Hadoop
Metrics2</a>. While it’s easy to configure Accumulo to send metrics, the
hard part is
-setting up and configuring a metrics visualization tool (i.e Graphite,
Ganglia, Grafana/InfluxDB) to collect
-and view these metrics.</p>
-
-<p>To ease this burden, this post describes how to send Accumulo metrics
to <a href="https://influxdb.com/">InfluxDB</a>, a time
series database,
-and make them viewable in <a
href="http://grafana.org/">Grafana</a>, a visualization
tool.</p>

href="http://grafana.org/">Grafana</a>. As for versions,
-the instructions below were written using InfluxDB v0.9.4.2 and Grafana
v2.5.0.</li>
- <li>Add the following to your InfluxDB configuration to configure it
accept metrics in Graphite
-format from Accumulo. The configuration below contains templates that
transform the Graphite
-metrics into a format that is usable in InfluxDB.
- <div class="highlighter-rouge"><div

-</code></pre></div> </div>
- </li>
- <li>Configure the Accumulo configuration file <code

to send Graphite
-metrics to InfluxDB. Below is example configuration. Remember to replace
<code
class="highlighter-rouge">&lt;INFLUXDB_HOST&gt;</code>
with
-the actual host.
- <div class="highlighter-rouge"><div
class="highlight"><pre
class="highlight"><code> *.period=30

- accumulo.sink.graphite.server_host=&lt;INFLUXDB_HOST&gt;
- accumulo.sink.graphite.server_port=2003
- accumulo.sink.graphite.metrics_prefix=accumulo
-</code></pre></div> </div>
- <p>Make sure the reporting frequency is set to 30 sec (i.e <code
class="highlighter-rouge">*.period=30</code>). This is
required if you are
-using the provided Grafana dashboards that is configured in the next
step.</p>
- </li>
- <li>Grafana needs to be configured to load dashboard JSON templates
from a directory. Before restarting
-Grafana, you should copy <a
href="https://raw.githubusercontent.com/apache/fluo-uno/master/conf/grafana/accumulo-dashboard.json">this
Accumulo dashboard template</a> to the <code
class="highlighter-rouge">dashboards/</code> directory
-configured below.

class="highlight"><pre
class="highlight"><code> [dashboards.json]
- enabled = true
- path = &lt;GRAFANA_HOME&gt;/dashboards
-</code></pre></div> </div>
- </li>
- <li>If you restart Grafana, you will see the Accumulo dashboard
configured but all of their charts will
-be empty unless you have Accumulo running and configured to send data to
InfluxDB. When you start
-sending data, you may need to refresh the dashboard page in the browser to
start viewing metrics.</li>
