+<h1 id="slider-chaos-monkey">Slider Chaos Monkey</h1>
+<p>Slider includes a built in <a
href="http://techblog.netflix.com/2012/07/chaos-monkey-released-into-wild.html";>Chaos
Monkey</a>.
+This is a service which runs inside the Slider Application Master, and randomly
+kills containers without any warning, or even the application master
itself.</p>
+<p>This Chaos Monkey is intended for testing. Netflix's original design runs
+against all their production applications hosted in Amazon's cloud. The slider
+Chaos Monkey also may be used in production, if desired, though it is not
something
+we would recommend, especially for any application where the cost of
+reacting to or recovering from failures is tangible. </p>
+<p>If used in production, note that YARN needs to be configured
+to tolerate the failure rate, and the Slider failure threshold
(<code>yarn.container.failure.threshold</code>)
+and window are configured to tolerate the increased failure rate.</p>
+<p>The Chaos Monkey works as follows</p>
+<ol>
+<li>The monkey wakes up at a configured interval "comes out to play".</li>
+<li>For each chaos action, the monkey then generates a random number</li>
+<li>If the probability of the chaos action is greater than this random number,
+the action is performed.</li>
+</ol>
+<p>As an example, if the probability of killing the AM is set to 50%, and the
+monkey interval is set to one hour, then one would expect over a 48 hour period
+for the AM to have failed approximately 24 times. As the check is random, it
is unlikey
+to be exactly this value, nor will the interval between failures be exactly
two hours.</p>
+<p>A monkey interval of 30 minutes and an AM kill probability of 25% would
result
+in the aggregate failure rate being approximately the same, but the interval
between failures
+would be different.</p>
+<h2 id="configuring-the-chaos-monkey">Configuring the Chaos Monkey</h2>
+<p>The Chaos Monkey is configured on a per-application basis, by setting
options
+in the <code>global</code> section of the internal resources file,
<code>internal.json</code></p>
+<p>Any option which takes a probability uses unit of hundreths of a percentage,
+that is <code>10000</code> units are equivalent to a probability of
<code>1</code>: a operation will always
+take place. A value of <code>100</code> is translated to 1%, a probability of
0.01. </p>
+<p>This unit is used to allow very small percentages to be expressed without
resorting
+to floating point numbers.</p>
+<p>the monkey can be enabled, after which the interval between checks must be
set.
+Available actions can then have their individidual probability set.</p>
+<h3 id="enabling-the-monkey">Enabling the Monkey</h3>
+<p>The option <code>internal.chaos.monkey.enabled</code> enables or disables
the monkey; it
+must equal <code>"true"</code> for the monkey to be enabled and other options
read.</p>
+<h3 id="interval">Interval</h3>
+<p>The interval (aggregated to produce a total interval) between checks to see
if
+<em>any</em> chaos action is to be triggered.</p>
+<ul>
+<li><code>internal.chaos.monkey.interval.days</code></li>
+<li><code>internal.chaos.monkey.interval.hours</code></li>
+<li><code>internal.chaos.monkey.interval.minutes</code></li>
+<li><code>internal.chaos.monkey.interval.seconds</code></li>
+</ul>
+<p>If not interval is set the chaos monkey does not start</p>
+<h3 id="startup-delay">Startup delay</h3>
+<p>The chaos monkey can be given a startup delay before it begins
+actions. The value defaults to the interval value (see above).</p>
+<ul>
+<li><code>internal.chaos.monkey.delay.days</code></li>
+<li><code>internal.chaos.monkey.delay.hours</code></li>
+<li><code>internal.chaos.monkey.delay.minutes</code></li>
+<li><code>internal.chaos.monkey.delay.seconds</code></li>
+</ul>
+<h2 id="application-master-kill">Application Master Kill</h2>
+<p>The probability of the AM being killed on a monkey check is:</p>
+<div class="codehilite"><pre><span class="n">internal</span><span
class="p">.</span><span class="n">chaos</span><span class="p">.</span><span
class="n">monkey</span><span class="p">.</span><span
class="n">probability</span><span class="p">.</span><span
class="n">amfailure</span>
+</pre></div>
+
+
+<p>When the monkey triggers this action, the AM kills itself. YARN is expected
to
+detect this and react by creating a new application master âwhile leaving the
+running application itself to continue uninterrupted.</p>
+<p>For the AM to recover from failures, YARN must be configured to support
application
+retries.</p>
+<p>As a restarted AM resets all its internal state, the Chaos Monkey itself
will be
+restarted with a new interval <em>which begins from the moment the AM is
restarted</em>.</p>
+<h2 id="container-kill">Container Kill</h2>
+<p>The probability of a container being killed in a single monkey "play"
is:</p>
+<div class="codehilite"><pre><span class="n">internal</span><span
class="p">.</span><span class="n">chaos</span><span class="p">.</span><span
class="n">monkey</span><span class="p">.</span><span
class="n">probability</span><span class="p">.</span><span
class="n">containerfailure</span>
+</pre></div>
+
+
+<p>When the monkey triggers this action, the current list of active YARN
containers
+being used by the application is enumerated, then one of the containers is
selected
+at random to be killed.</p>
+<p>The Slider Application Master is expected to notice this event and respond
by
+requesting and re-instantiating a replacement failure.</p>
+<p>The Slider Application should be configured in its
<code>resources.json</code> file to
+tolerate a failure rate.</p>
+<p>If there are no containers hosting application components at the time
+the chaos monkey performs its actions, then no container will be killed.</p>
+<h2 id="am-launch-failure">AM Launch Failure</h2>
+<p>The launch failure is a special check at startup, if the monkey is enabled:
+it defines the probability that the launch itself will fail.</p>
+<p>It is tested precisely once per application attempt, at launch startup</p>
+<div class="codehilite"><pre><span class="n">internal</span><span
class="p">.</span><span class="n">chaos</span><span class="p">.</span><span
class="n">monkey</span><span class="p">.</span><span
class="n">probability</span><span class="p">.</span><span
class="n">amlaunchfailure</span>
+</pre></div>
+
+
+<p>Note that the chaos monkey must be enabled for this check, where that means
+1. the monkey must be enabled with
<code>internal.chaos.monkey.enabled=true</code>
+1. A non-zero monkey interval must be set via the
<code>internal.chaos.monkey.interval</code>
+properties</p>
+<h1 id="example">Example</h1>

+
+<p>This configuration</p>
+<ol>
+<li>Enables the Chaos Monkey</li>
+<li>Set the interval to 1h 30m; 90 minutes.</li>
+<li>Sets the probability of a container failure to 10%</li>
+<li>Sets the probability of an application master failure to 0.05%</li>
+</ol>
+<p>With these values, over an 24 hour period, the probability of a container
+being killed is <code>16 * 1000 / 10000</code>: <code>1.6</code>, </p>
+<p>That is, at least one container is likely to have been killed over the
day.</p>
+<p>The probability of the AM failing is significantly lower</p>
+<div class="codehilite"><pre>16 <span class="o">*</span> 0<span

<span class="p">=</span> 0<span class="p">.</span>8<span class="c">%</span>
+</pre></div>
+
+
+<p>If any probability is set to zero, such as: </p>

+

+<p>Then that check is never made âhere the AM will never be killed by
+the Chaos Monkey.</p>
