title: Logstash in reading files issues
body: <p>I have written a logstash conf file to read through logs. It run fine when I specify the log path to a single file. However, if I made it to *.log, it can't run any files. How can I resolve it?</p>
  
  <p>Here is the one which works.</p>
  
  <pre><code>input{
      stdin{}
      file{
          type =&gt; "txt"
          path =&gt; "C:\HA\accesslog\trial.log"
          start_position =&gt; "beginning"
      }
  }
  filter{
      grok{
      match =&gt; {"message" =&gt; ["%{IP:ClientAddr}%{SPACE}%{NOTSPACE:access_date}%{SPACE}%{TIME:access_time}%{SPACE}%{NOTSPACE:VirtualHost}%{SPACE}%{WORD:cs-method}%{SPACE}%{PATH:cs-uri-stem}%{SPACE}%{PROG:Protocol}%{SPACE}%{NUMBER:sc-status}%{SPACE}%{NUMBER:bytes}%{SPACE}%{NOTSPACE:RequestedSessionId}%{SPACE}%{PROG:Ecid}%{SPACE}%{NUMBER:ThreadId}%{SPACE}%{NUMBER:EndTs}%{SPACE}%{NUMBER:time-taken}"]}
          }
      if "_grokparsefailure" in [tags] {
          drop { }
      }   
  }
  output{
      elasticsearch { 
          hosts =&gt; ["localhost:9200"] 
          index =&gt; "logstash-%{+YYYY.MM.dd}"
          template_overwrite =&gt; true
      }
      stdout { codec =&gt; rubydebug }   
  }
  </code></pre>
  
  <p>When I change path to </p>
  
  <blockquote>
    <p>path => "C:\HA\accesslog\*.log"</p>
  </blockquote>
  
  <p>It could not work.</p>
