<h1>Tracing</h1> + + <p>It can be difficult to determine why some operations are taking longer +than expected. For example, you may be looking up items with very low +latency, but sometimes the lookups take much longer. Determining the +cause of the delay is difficult because the system is distributed, and +the typical lookup is fast.</p> + +<p>Accumulo has been instrumented to record the time that various +operations take when tracing is turned on. The fact that tracing is +enabled follows all the requests made on behalf of the user throughout +the distributed infrastructure of accumulo, and across all threads of +execution.</p> + +<p>These time spans will be inserted into the <code class="highlighter-rouge">trace</code> table in +Accumulo. You can browse recent traces from the Accumulo monitor +page. You can also read the <code class="highlighter-rouge">trace</code> table directly like any +other table.</p> + +<p>The design of Accumuloâs distributed tracing follows that of <a href="http://research.google.com/pubs/pub36356.html";>Googleâs Dapper</a>.</p> + +<h2 id="tracers">Tracers</h2> + +<p>To collect traces, Accumulo needs at least one tracer server running. If you are using <code class="highlighter-rouge">accumulo-cluster</code> to start your cluster, +configure your server in <code class="highlighter-rouge">conf/tracers</code>. The server collects traces from clients and writes them to the <code class="highlighter-rouge">trace</code> table. The Accumulo +user that the tracer connects to Accumulo with can be configured with the following properties (see the <a href="/docs/unreleased/administration/configuration-management">configuration management</a> +page for setting Accumulo server properties)</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>trace.user +trace.token.property.password +</code></pre> +</div> + +<p>Other tracer configuration properties include</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>trace.port.client - port tracer listens on +trace.table - table tracer writes to +trace.zookeeper.path - zookeeper path where tracers register +</code></pre> +</div> + +<p>The zookeeper path is configured to /tracers by default. If +multiple Accumulo instances are sharing the same ZooKeeper +quorum, take care to configure Accumulo with unique values for +this property.</p> + +<h2 id="configuring-tracing">Configuring Tracing</h2> + +<p>Traces are collected via SpanReceivers. The default SpanReceiver +configured is org.apache.accumulo.core.trace.ZooTraceClient, which +sends spans to an Accumulo Tracer process, as discussed in the +previous section. This default can be changed to a different span +receiver, or additional span receivers can be added in a +comma-separated list, by modifying the property</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>trace.span.receivers +</code></pre> +</div> + +<p>Individual span receivers may require their own configuration +parameters, which are grouped under the trace.span.receiver.* +prefix. ZooTraceClient uses the following properties. The first +three properties are populated from other Accumulo properties, +while the remaining ones should be prefixed with +trace.span.receiver. when set in the Accumulo configuration.</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>tracer.zookeeper.host - populated from instance.zookeepers +tracer.zookeeper.timeout - populated from instance.zookeeper.timeout +tracer.zookeeper.path - populated from trace.zookeeper.path +tracer.send.timer.millis - timer for flushing send queue (in ms, default 1000) +tracer.queue.size - max queue size (default 5000) +tracer.span.min.ms - minimum span length to store (in ms, default 1) +</code></pre> +</div> + +<p>Note that to configure an Accumulo client for tracing, including +the Accumulo shell, the client configuration must be given the same +trace.span.receivers, trace.span.receiver.*, and trace.zookeeper.path +properties as the servers have.</p> + +<p>Hadoop can also be configured to send traces to Accumulo, as of +Hadoop 2.6.0, by setting properties in Hadoopâs core-site.xml +file. Instead of using the trace.span.receiver.* prefix, Hadoop +uses hadoop.htrace.*. The Hadoop configuration does not have +access to Accumuloâs properties, so the +hadoop.htrace.tracer.zookeeper.host property must be specified. +The zookeeper timeout defaults to 30000 (30 seconds), and the +zookeeper path defaults to /tracers.
