<p>The <code>monitor</code> node provides a nagios control panel that will give you a view into the health and status of all the servers and all the services. It will also spam you with alerts if something goes down.</p>
<h2><a name="topology"></a>Topology</h2>
<p>Currently, you can have zero or one <code>monitor</code> nodes defined. It is required that the monitor be on the webapp node. It was not designed to be run as a separate node service.</p>
<h2><a name="configuration"></a>Configuration</h2>
<ul>
<li><code>nagios.environments</code>: By default, the monitor node will monitor all servers in all environments. You can <strong>optionally</strong> restrict the environments to the ones you specify.</li>
</ul>
<p>For example:</p>
<pre><code>{
"nagios": {
"environments": ["unstable", "production"]
}
}
</code></pre>
<h2><a name="access-nagios-web"></a>Access nagios web</h2>
<p>To open the nagios control panel:</p>
<pre><code>workstation$ leap open monitor
</code></pre>
<p>This will open a web browser window with the appropriate URL, including the nagios username and password.</p>
<p>If the URL does not open because of HSTS or DNS problems, pass the <code>--ip</code> option to <code>leap</code>.</p>
<p>If you are using an older version of <code>leap</code> command that doesn’t include <code>leap open</code>, you can determine the nagio parameters manually:</p>
<p>Step 1. find the domain:</p>
<pre><code>workstation$ export DOMAIN=$(leap ls --print webapp.domain monitor | grep . | cut -f3 -d' ')
</code></pre>
<p>Step 2. find the username:</p>
<pre><code>workstation$ export USERNAME="nagiosadmin"
</code></pre>
<p>Step 3. find the password:</p>
<pre><code>workstation$ export PASSWORD=$(grep nagios_admin_password secrets.json | cut -f4 -d\")
</code></pre>
<p>Step 4. put it all together:</p>
<pre><code>workstation$ sensible-browser "https://$USERNAME:$PASSWORD@$DOMAIN/nagios3"
</code></pre>
