Monitoring</h1>
+<h2 id="monitor-requirements">Monitor Requirements</h2>
+<p>This application aims to monitor user activities on HDFS via the hdfs audit
log. Once any abnormal user activity is detected, an alert is sent in several
seconds. The whole pipeline of this application is</p>
+<ul>
+<li>
+<p>Kafka ingest: this application consumes data from Kafka. In other words,
users have to stream the log into Kafka first. </p>
+</li>
+<li>
+<p>Data re-procesing, which includes raw log parser, ip zone joiner,
sensitivity information joiner. </p>
+</li>
+<li>
+<p>Kafka sink: parsed data will flows into Kafka again, which will be consumed
by the alert engine. </p>
+</li>
+<li>
+<p>Policy evaluation: the alert engine (hosted in Alert Engine app) evaluates
each data event to check if the data violate the user defined policy. An alert
is generated if the data matches the policy.</p>
+</li>
+</ul>

+<h2 id="how-to-collect-the-log">How to collect the log</h2>
+<p>To collect the raw audit log on namenode servers, a log collector is
needed. Users can choose any tools they like. There are some common solutions
available: <a
href="https://www.elastic.co/guide/en/logstash/current/getting-started-with-logstash.html";>logstash</a>,
<a
href="https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-getting-started.html";>filebeat</a>,
log4j appender, etcs. </p>

+<li>
+<p>Make sure already setup a site (here use a demo site named "sandbox").</p>
+</li>
+<li>
+<p>Install "Map Reduce History Job" app in eagle server(Take this application
as an example).</p>
+</li>
+<li>
+<p>Configure Application settings</p>
+<p><img alt="application configures" src="../include/images/jpm_configure.png"
/></p>
+</li>
+<li>
+<p>Ensure a kafka topic named {SITE_ID}_map_reduce_failed_job (In current
guide, it should be sandbox_map_reduce_failed_job) will be created.</p>
+</li>
+<li>
+<p>Click "Install" button then you will see the
MAP_REDUCE_FAILED_JOB_STREAM_{SITE_ID} in Alert->Streams.
+ <img alt="application configures" src="../include/images/jpm_streams.png"

+ This application will write stream data to kafka topic(created by last
step)</p>
+</li>
+</ul>
+<h2 id="integration-with-alert-engine">Integration With Alert Engine</h2>
+<p>In order to integrate applications with alert engine and send alerts,
follow below steps(Take Map Reduce History Job application as an example):</p>
+<ul>
+<li>
+<p><strong>define stream and configure data sink</strong></p>
+<ul>
+<li>define stream in resource/META-INF/providers/xxxProviders.xml
+For example, MAP_REDUCE_FAILED_JOB_STREAM_{SITE_ID}</li>
+<li>configure data sink
+For example, create kafka topic {SITE_ID}_map_reduce_failed_job</li>
+</ul>
+</li>
+<li>
+<p><strong>define policy</strong></p>
+</li>
+</ul>
+<p>For example, if you want to receive map reduce job failure alerts, you can
define policies (SiddhiQL) as the following:</p>
+<pre><code class="sql">from
map_reduce_failed_job_stream[site=="sandbox" and
currentState=="FAILED"]
+select site, queue, user, jobType, jobId, submissionTime, trackingUrl,
startTime, endTime
+group by jobId insert into map_reduce_failed_job_stream_out
+</code></pre>
+
+<p><img alt="define policy" src="../include/images/jpm_define_policy.png"
/></p>
+<ul>
+<li><strong>view alerts</strong></li>
+</ul>
+<p>You can view alerts in Alert->alerts page.</p>
+<h2 id="stream-schema_1">Stream Schema</h2>
+<p>All columns above are predefined in stream map_reduce_failed_job_stream
defined in</p>
+<pre><code>eagle-jpm/eagle-jpm-mr-history/src/main/resources/META-INF/providers/org.apache.eagle.jpm.mr.history.MRHistoryJobApplicationProvider.xml
+</code></pre>
+<p>Then, enable the policy in web ui after it's created. Eagle will schedule
it automatically.</p>

href="https://github.com/haoch/incubator-eagle/tree/master/eagle-examples/eagle-app-example";>eagle-app-example</a></p>
+<p><strong>Description</strong> - A typical eagle application is mainly
consisted of:</p>
+<ul>
+<li>
+<p><strong>Application</strong>: define core execution process logic
inheriting from org.apache.eagle.app.Application, which is also implemented
ApplicationTool to support Application to run as standalone process like a
Storm topology through command line.</p>
+</li>
+<li>
+<p><strong>ApplicationProvider</strong>: the interface to package application
with descriptor metadata, also used as application SPI to dynamically load new
application types.</p>
+</li>
+<li>
+<p><strong>META-INF/providers/${APP_PROVIDER_CLASS_NAME}.xml</strong>: support
to easily describe applicationâs descriptor with declarative XML like:</p>
