Question

我阅读下面的文章，了解我建立ELK环境的logstash技术。 https://tpodolak.com/blog/tag/kibana/


input {
    file {
        path => ["C:/logs/*.log"]
        start_position => beginning
        ignore_older => 0

    }
}
filter {
    grok {
        match => { "message" => "TimeStamp=%{TIMESTAMP_ISO8601:logdate} CorrelationId=%{UUID:correlationId} Level=%{LOGLEVEL:logLevel} Message=%{GREEDYDATA:logMessage}" }
    }
    # set the event timestamp from the log
    # https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html
    date {
         match => [ "logdate", "yyyy-MM-dd HH:mm:ss.SSSS" ]
        target => "@timestamp"
    }
}
output {
    elasticsearch {
        hosts => "localhost:9200"
    }
    stdout {}
}

我在logstash.conf中添加了输入路径C / logs / * .log。我有一个非空的test.log文件，它有：


TimeStamp=2016-07-20 21:22:46.0079 CorrelationId=dc665fe7-9734-456a-92ba-3e1b522f5fd4 Level=INFO Message=About
TimeStamp=2016-07-20 21:22:46.0079 CorrelationId=dc665fe7-9734-456a-92ba-3e1b522f5fd4 Level=INFO Message=About
TimeStamp=2016-11-01 00:13:01.1669 CorrelationId=77530786-8e6b-45c2-bbc1-31837d911c14 Level=INFO Message=Request completed with status code: 200

根据上述文章。我必须看到我的日志在elasticsearch里面。（来自＆＃34; https://tpodolak.com/blog/tag/kibana/＆＃34;样本结果）但是我的结果是，如果我在浏览器上写这个地址：http://localhost:9200/_cat/indices?v我在elasticsearch中看不到logstash日志？在弹性搜索中存储的logstash日志在哪里？ logstash.conf看起来不错。但是没有满意的结果。结果是。我想通过logstash获取C / logs / *下的所有日志.log to elastic？但是我的logstash.conf中的错误是什么？

我的日志（C：\ monitoring \ logstash \ logs \ C：\ monitoring \ logstash \ logs.log）：

首先，您有一些配置问题：

Elasticsearch中的主机应该是一个数组（例如hosts => ["myHost:myPort3]），请参阅the doc
使用通配符的Windows上的文件应使用正斜杠而不是向后（请参阅this issue）
您的日期过滤器正在寻找一个字段＆＃34; logdate＆＃34;什么时候应该寻找领域＆＃34; TimeStamp＆＃34; （给出你的日志文件）
我方便的一个设置是sincedb_path，因为Logstash不会再尝试解析它已经解析过的文件（它会检查.sincedb以查看它是否已经解析了一个文件，默认位于$ HOME / .sincedb，在使用相同的日志文件进行测试时解析之间需要删除它）

这就是为什么经过一些研究（实际上很多，不是Windows用户），我可以想出这个有效的配置：

input {
    file {
        path => "C:/some/log/dir/*"
        start_position => beginning
        ignore_older => 0
        sincedb_path => "NIL" #easier to remove from the current directory, the file will be NIL.sincedb

    }
}
filter {
    grok {
        match => { "message" => "TimeStamp=%{TIMESTAMP_ISO8601:logdate} CorrelationId=%{UUID:correlationId} Level=%{LOGLEVEL:logLevel} Message=%{GREEDYDATA:logMessage}" }
    }
    # set the event timestamp from the log
    # https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html
    date {
         match => [ "TimeStamp", "yyyy-MM-dd HH:mm:ss.SSS" ]
        target => "@timestamp"
    }
}
output {
    elasticsearch {
        hosts => ["localhost:9200"]
    }
    stdout {}
}

为什么没有logstash生成日志？
