body: <p>When I'm trying to run Prometheus alert manager with <code>alertmanager --config.file /etc/alertmanager/alertmanager.yml</code></p>
  <p>It giving me error like</p>
  <pre><code>   $ alertmanager --config.file /etc/alertmanager/alertmanager.yml

  </code></pre>
  <p>I checked the listening port by <code>netstat -tnlp</code></p>
  <pre><code>Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

  </code></pre>
  <p>I tried too kill the process with <code>sudo kill -9 $(sudo lsof -t -i:9094)</code> and <code>fuser -n tcp -k 9094</code></p>
  <p>I'm not getting how to resolve that issue.</p>
