<p id="rl-tm-configure">Traffic Monitor is configured via two JSON configuration files, <code class="docutils literal"><span class="pre">traffic_ops.cfg</span></code> and <code class="docutils literal"><span class="pre">traffic_monitor.cfg</span></code>, by default located in the <code class="docutils literal"><span class="pre">conf</span></code> directory in the install location.</p>
<p>The <code class="docutils literal"><span class="pre">traffic_ops.cfg</span></code> config contains Traffic Ops connection information. Specify the URL, username, and password for the instance of Traffic Ops for which this Traffic Monitor is a member.</p>
<p>The <code class="docutils literal"><span class="pre">traffic_monitor.cfg</span></code> config contains log file locations, as well as detailed application configuration variables, such as processing flush times and initial poll intervals.</p>
<p>Once started with the correct configuration, Traffic Monitor downloads its configuration from Traffic Ops and begins polling caches. Once every cache has been polled, health protocol state is available via RESTful JSON endpoints.</p>
