<h1>Monitoring</h1>
<p>Monitoring tools capture, analyze and display information for a web
application's execution. Every application has issues arise throughout
all levels of the web stack. Monitoring tools provide transparency so
developers and operations teams can respond and fix problems.</p>
<h2>Why is monitoring necessary?</h2>
<p>Capturing and analyzing data about your production environment is critical
to proactively deal with stability, performance, and errors in a web
application.</p>
<h2>Monitoring layers</h2>
<p>There are several important resources to monitor on the operating system
and network level of a web stack.</p>
<ol>
<li>CPU utilization</li>
<li>Memory utilization</li>
<li>Persistence storage consumed versus free</li>
<li>Network bandwidth and latency</li>
</ol>
<p>Application level monitoring encompasses several aspects. The amount of time
and resources dedicated to each aspect will vary based on whether an
application is read-heavy, write-heavy, or subject to rapid swings in traffic.</p>
<ol>
<li>Application warnings and errors (500-level HTTP errors)</li>
<li>Application code performance</li>
<li>Template rendering time</li>
<li>Browser rendering time for the application</li>
<li>Database querying performance</li>
</ol>
<h2>Monitoring Third Party Services</h2>
<p><a href="http://newrelic.com/">New Relic</a>. Application and database monitoring as
well as plug ins for capturing and analyzing additional data about tools in
your stack.</p>
<p><a href="http://copperegg.com/">CopperEgg</a> is lower-level monitoring on server and
infrastructure. It's popular with DevOps shops that are making changes to
their production environments and want immediate feedback on the results
of those modifications.</p>
<p><a href="http://status.io/">Status.io</a> focuses on uptime and response metrics
transparency for your users.</p>
<p><a href="http://www.pagerduty.com/">PagerDuty</a> alerts a designated person or group
if there are stability, performance, or uptime issues with an application.</p>
<h2>Open Source Monitoring Projects</h2>
<p><a href="https://github.com/etsy/statsd/">statsd</a> is a node.js network daemon that
listens for metrics and aggregates them for transfer into another service
such as Graphite.</p>
<p><a href="https://graphite.readthedocs.org/en/latest/overview.html">Graphite</a> stores
time-series data and displays them in graphs through a Django web application.</p>
<p><a href="http://github.hubspot.com/bucky/">Bucky</a> measures the performance of a
web application from end user's browsers and sends that data back to the
server for collection.</p>
<p><a href="http://sensuapp.org/">Sensu</a> is an open source monitoring framework
written in Ruby but applicable to any programming language web application.</p>
<p><a href="http://vimeo.github.io/graph-explorer/">Graph Explorer</a> by Vimeo is a
Graphite-based dashboard with added features and a slick design.</p>
