title: nginx log analysis with goaccess
body: <p>I want to parse and analyze the nginx logs with <a href="http://goaccess.prosoftcorp.com/" rel="noreferrer">goaccess</a> and take a report from the analyzed logs.
  But, when I run the <code>zcat -f access.log.*.gz | goaccess -a -c</code> command, it gives me the following error :</p>
  
  <pre><code>GoAccess - version 0.5 - Jun 26 2012 04:30:08
  An error has occurred
  Error occured at: parser.c - process_log - 584
  Message: No date format was found on your conf file.
  </code></pre>
  
  <p>I tried to add the line <code>date_format %D %T</code> to .goaccessrc file but I got another error which is:</p>
  
  <pre><code>GoAccess - version 0.5 - Jun 26 2012 04:30:08
  An error has occurred
  Error occured at: parser.c - process_log - 588
  Message: No log format was found on your conf file.
  </code></pre>
  
  <p>I think it asks for the date and log formats that nginx uses. 
  but I have no any date or log format in my nginx configuration. </p>
  
  <p>Additionally, I've tried to use a previous version of goaccess(0.4.2 version) 
  and the <code>zcat -f access.log.*.gz | goaccess -a -c</code> command works fine. 
  it doesn't asks for any date or log format and i can view the goaccess menu and 
  i can view any data that want.</p>
  
  <p>But when I try to get a html report with <code>zcat -f access.log.*.gz | goaccess -a -c &gt; report.html</code>
  command, it does nothing. it just waits and waits.(without giving any warning or error)</p>
  
  <p>Note: i've checked this webpages and if you want to take a look too.</p>
