Logstash和ElasticSearch之間的數據丟失

Question

我正在嘗試使用Logstash解析IIS錯誤XML文件，然后將這些錯誤存儲在Elasticsearch中並顯示在Kibana中。

這是我的logstash.conf文件：

input 
{
    file{
        path => ["C:/inetpub/logs/FailedReqLogFiles/*/*.xml"]
        start_position => "beginning"
        # filter is not thread safe, so have to move the multiline into the input
        codec => multiline{
            #pattern => "^</failedRequest>"
            pattern => "^<\?xml version"
            negate => true
            what => "previous"
            max_lines => 12000
        }
        sincedb_path => "C:/Users/ss/Source/elk/logstash/bin/.sincedb"
    }
}

filter{
    xml{
        store_xml => "false"
        source => "message"
        target => "EVENT"
        xpath => [
          "/failedRequest/@url", "url",
          "/failedRequest/@appPoolId", "appPoolId",
          "/failedRequest/@verb", "verb",
          "/failedRequest/@statusCode", "statusCode"
        ]
    }    
}

output 
{
    elasticsearch{
        hosts => ["100.202.191.77:9200"]
        index => "testserver-logstash"   
        flush_size => 1     
    }
    stdout 
    {
        codec => rubydebug
    }
    file{
        path => "C:/Users/ss/Source/elk/logstash/bin/test.log"
    }
}

日志文件目錄為：

C:\inetpub\logs\FailedReqLogFiles\W3SVC3
C:\inetpub\logs\FailedReqLogFiles\W3SVC4
C:\inetpub\logs\FailedReqLogFiles\W3SVC5

這些目錄中包含的日志文件包括：fr000001.xml，fr000002.xml，fr000003.xml，fr000004.xml等。

xml文件的結構如下：

<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type='text/xsl' href='freb.xsl'?>
<!-- saved from url=(0014)about:internet -->
<failedRequest url="https://aaa.bbb.com:443/ddd.aspx" 
               siteId="3"
               appPoolId="aaa.bbb.com" 
               processId="15168"
               verb="GET" 
               remoteUserName=""
               userName=""
               tokenUserName="NT AUTHORITY\IUSR"
               authenticationType="anonymous"
               activityId="{00000000-0000-0000-0200-0080030000FF}"
               failureReason="STATUS_CODE"
               statusCode="500" 
               triggerStatusCode="500"
               timeTaken="368584"
               xmlns:freb="http://schemas.microsoft.com/win/2006/06/iis/freb"
               >
<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">blablabla
</Event>
</failedRequest> 

我得到的問題是：總共有13個xml日志文件。 我可以在標准輸出和test.log中看到logstash輸出正確打印了所有這13個文件的已解析xml，但是，在Kibana中，我只能看到13個xml文件中的4個的數據，其余9個文件是失蹤。

我是ELK堆棧的新手，真的被卡在這里。 希望有人可以幫助我。 提前致謝。

我下線評論，它看起來像logstash工作。

 flush_size => 1
