<h1 id="what-is-zabbix-">What is Zabbix?</h1>
<p>Zabbix is an enterprise-class open source distributed monitoring solution.</p>
<p>Zabbix is software that monitors numerous parameters of a network and the health and integrity of servers. Zabbix uses a flexible notification mechanism that allows users to configure e-mail based alerts for virtually any event. This allows a fast reaction to server problems. Zabbix offers excellent reporting and data visualisation features based on the stored data. This makes Zabbix ideal for capacity planning.</p>

<h1 id="what-is-the-image-">What is the image?</h1>
<p>The image is used to receive SNMP traps, store them to a log file and provide access to Zabbix to collected SNMP trap messsages.</p>
<h1 id="zabbix-snmptraps-images">Zabbix snmptraps images</h1>
<p>These are the only official Zabbix snmptraps Podman images. Images are updated when new releases are published.</p>

</code></pre><h2 id="container-shell-access-and-viewing-zabbix-snmptraps-logs">Container shell access and viewing Zabbix snmptraps logs</h2>
<p>The <code>podman exec</code> command allows you to run commands inside a Podman container. The following command line will give you a bash shell inside your <code>zabbix-snmptraps</code> container:</p>
<pre><code class="lang-console">$ podman exec -ti <span class="hljs-keyword">some</span>-zabbix-snmptraps /bin/bash
</code></pre>
<p>The Zabbix snmptraps log is available through Podman&#39;s container log:</p>
<pre><code class="lang-console">$ podman logs  <span class="hljs-keyword">some</span>-zabbix-snmptraps
</code></pre>
<h2 id="environment-variables">Environment Variables</h2>
<p>When you start the <code>zabbix-snmptraps</code> image, you can adjust the configuration by passing one or more environment variables on the <code>podman run</code> command line.</p>
<h3 id="-zbx_snmp_trap_date_format-"><code>ZBX_SNMP_TRAP_DATE_FORMAT</code></h3>
<p>This variable is represent date and time format in the output <code>snmptraps.log</code> file. By default, value is <code>+%Y-%m-%dT%T%z</code>. Please, refer to <code>date</code> command man for more details about date and time format.</p>
