<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>
|
||||
<p>For more information and related downloads for Zabbix components, please visit <a href="https://hub.docker.com/u/zabbix/">https://hub.docker.com/u/zabbix/</a> and <a href="https://zabbix.com">https://zabbix.com</a></p>
|
||||
<h1 id="what-is-zabbix-server-">What is Zabbix server?</h1>
|
||||
<p>Zabbix server is the central process of Zabbix software.</p>
|
||||
<p>The server performs the polling and trapping of data, it calculates triggers, sends notifications to users. It is the central component to which Zabbix agents and proxies report data on availability and integrity of systems. The server can itself remotely check networked services (such as web servers and mail servers) using simple service checks.</p>
|
||||
<h1 id="zabbix-server-images">Zabbix server images</h1>
|
||||
<p>Images are updated when new releases are published.</p>
|
||||
<p>The image uses PostgreSQL database. It uses the next procedure to start:</p>
|
||||
<ul>
|
||||
<li>Checking database availability</li>
|
||||
<li>Checking of having <code>POSTGRES_DB</code> database. Creating <code>POSTGRES_DB</code> database name if it does not exist</li>
|
||||
<li>Checking of having <code>dbversion</code> table. Creating Zabbix server database schema and upload initial data sample if no <code>dbversion</code> table</li>
|
||||
</ul>
|
||||
<h1 id="how-to-use-this-image">How to use this image</h1>
|
||||
<h2 id="start-zabbix-server-pgsql-">Start <code>zabbix-server-pgsql</code></h2>
|
||||
<p>Start a Zabbix server container as follows:</p>
|
||||
<pre><code>podman <span class="hljs-keyword">run</span><span class="bash"> --name some-zabbix-server-pgsql <span class="hljs-_">-e</span> DB_SERVER_HOST=<span class="hljs-string">"some-postgres-server"</span> <span class="hljs-_">-e</span> POSTGRES_USER=<span class="hljs-string">"some-user"</span> <span class="hljs-_">-e</span> POSTGRES_PASSWORD=<span class="hljs-string">"some-password"</span> <span class="hljs-_">-d</span> zabbix/zabbix-server-pgsql:tag</span>
|
||||
</code></pre><p>Where <code>some-zabbix-server-pgsql</code> is the name you want to assign to your container, <code>some-postgres-server</code> is IP or DNS name of PostgreSQL server, <code>some-user</code> is user to connect to Zabbix database on PostgreSQL server, <code>some-password</code> is the password to connect to PostgreSQL server and <code>tag</code> is the tag specifying the version you want.</p>
|
||||
<blockquote>
|
||||
<p>[!NOTE]
|
||||
Zabbix server has possibility to execute <code>fping</code> utility to perform ICMP checks. When containers are running in rootless mode or with specific restrictions environment, you may face errors related to fping:
|
||||
<code>fping: Operation not permitted</code>
|
||||
or
|
||||
lost all packets to all resources
|
||||
in this case add <code>--cap-add=net_raw</code> to <code>podman run</code> or <code>podman run</code> commands.
|
||||
Additionally fping executing in non-root environments can require sysctl modification:
|
||||
<code>net.ipv4.ping_group_range=0 1995</code>
|
||||
where 1995 is <code>zabbix</code> GID.</p>
|
||||
</blockquote>
|
||||
<h2 id="container-shell-access-and-viewing-zabbix-server-logs">Container shell access and viewing Zabbix server 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-server-pgsql</code> container:</p>
|
||||
<pre><code class="lang-console">$ podman exec -ti <span class="hljs-keyword">some</span>-zabbix-server-pgsql /bin/bash
|
||||
</code></pre>
|
||||
<p>The Zabbix server log is available through Podman's container log:</p>
|
||||
<pre><code class="lang-console">$ podman logs <span class="hljs-keyword">some</span>-zabbix-server-pgsql
|
||||
</code></pre>
|
||||
<h2 id="environment-variables">Environment Variables</h2>
|
||||
<p>When you start the <code>zabbix-server-pgsql</code> image, you can adjust the configuration of the Zabbix server by passing one or more environment variables on the <code>podman run</code> command line.</p>
|
||||
<h3 id="-db_server_host-"><code>DB_SERVER_HOST</code></h3>
|
||||
<p>This variable is IP or DNS name of PostgreSQL server. By default, value is 'postgres-server'</p>
|
||||
<h3 id="-db_server_port-"><code>DB_SERVER_PORT</code></h3>
|
||||
<p>This variable is port of PostgreSQL server. By default, value is '5432'.</p>
|
||||
<h3 id="-postgres_user-postgres_password-postgres_user_file-postgres_password_file-"><code>POSTGRES_USER</code>, <code>POSTGRES_PASSWORD</code>, <code>POSTGRES_USER_FILE</code>, <code>POSTGRES_PASSWORD_FILE</code></h3>
|
||||
<p>These variables are used by Zabbix server to connect to Zabbix database. With the <code>_FILE</code> variables you can instead provide the path to a file which contains the user / the password instead. Without Docker Swarm or Kubernetes you also have to map the files. Those are exclusive so you can just provide one type - either <code>POSTGRES_USER</code> or <code>POSTGRES_USER_FILE</code>!</p>
|
||||
<pre><code class="lang-console">podman run --name some-zabbix-server-pgsql -e DB_SERVER_HOST=<span class="hljs-string">"some-postgres-server"</span> -v .<span class="hljs-regexp">/.POSTGRES_USER:/</span>run<span class="hljs-regexp">/secrets/</span>POSTGRES_USER -e POSTGRES_USER_FILE=<span class="hljs-regexp">/run/</span>secrets<span class="hljs-regexp">/POSTGRES_USER -v ./</span>.<span class="hljs-string">POSTGRES_PASSWORD:</span><span class="hljs-regexp">/run/</span>secrets<span class="hljs-regexp">/POSTGRES_PASSWORD -e POSTGRES_PASSWORD_FILE=/</span>var<span class="hljs-regexp">/run/</span>secrets<span class="hljs-regexp">/POSTGRES_PASSWORD -d zabbix/</span>zabbix-server-<span class="hljs-string">pgsql:</span>tag

|
||||
<p>With Docker Swarm or Kubernetes this works with secrets. That way it is replicated in your cluster!</p>
|
||||
<pre><code class="lang-console"><span class="hljs-built_in">printf</span> <span class="hljs-string">"zabbix"</span> | podman secret create POSTGRES_USER -

|
||||
</code></pre>
|
||||
<p>By default, values for <code>POSTGRES_USER</code> and <code>POSTGRES_PASSWORD</code> are <code>zabbix</code>, <code>zabbix</code>.</p>
|
||||
<h3 id="-postgres_db-"><code>POSTGRES_DB</code></h3>
|
||||
<p>The variable is Zabbix database name. By default, value is <code>zabbix</code>.</p>
|
||||
<h3 id="-postgres_use_implicit_search_path-"><code>POSTGRES_USE_IMPLICIT_SEARCH_PATH</code></h3>
|
||||
<p>In some setups, for example including <a href="https://www.pgbouncer.org">PgBouncer</a>, setting the <code>search_path</code> via connection parameters fails. If this variable is set to <code>"true"</code>, the image skips setting the <code>search_path</code> and trusts that the <code>search_path</code> of the Zabbix user is setup correctly in PostgreSQL database.</p>
|
||||
<h3 id="-zbx_loadmodule-"><code>ZBX_LOADMODULE</code></h3>
|
||||
<p>The variable is list of comma separated loadable Zabbix modules. It works with volume <code>/var/lib/zabbix/modules</code>. The syntax of the variable is <code>dummy1.so,dummy2.so</code>.</p>
|
||||
<h3 id="-zbx_debuglevel-"><code>ZBX_DEBUGLEVEL</code></h3>
|
||||
<p>The variable is used to specify debug level. By default, value is <code>3</code>. It is <code>DebugLevel</code> parameter in <code>zabbix_server.conf</code>. Allowed values are listed below:</p>
|
||||
<ul>
|
||||
<li><code>0</code> - basic information about starting and stopping of Zabbix processes;</li>
|
||||
<li><code>1</code> - critical information</li>
|
||||
<li><code>2</code> - error information</li>
|
||||
<li><code>3</code> - warnings</li>
|
||||
<li><code>4</code> - for debugging (produces lots of information)</li>
|
||||
<li><code>5</code> - extended debugging (produces even more information)</li>
|
||||
</ul>
|
||||
<h3 id="-zbx_timeout-"><code>ZBX_TIMEOUT</code></h3>

<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>
|
||||

<p>When you start the <code>zabbix-web-nginx-pgsql</code> image, you can adjust the configuration of the Zabbix web interface by passing one or more environment variables on the <code>podman run</code> command line.</p>
|
||||
<h3 id="-zbx_server_host-"><code>ZBX_SERVER_HOST</code></h3>
|
||||
<p>This variable is IP or DNS name of Zabbix server. By default, value is <code>zabbix-server</code>.</p>

|
||||
<p>These variables are used by Zabbix web interface to connect to Zabbix database. With the <code>_FILE</code> variables you can instead provide the path to a file which contains the user / the password instead. Without Docker Swarm or Kubernetes you also have to map the files. Those are exclusive so you can just provide one type - either <code>POSTGRES_USER</code> or <code>POSTGRES_USER_FILE</code>!</p>
