为什么logstash不产生日志？

Question

我阅读了以下文章以了解我建立 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。我的 test.log 文件不为空，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

根据上面的文章。我必须看到我的日志在弹性搜索中。 （来自“https://tpodolak.com/blog/tag/kibana/”示例结果） 但是如果我将这个地址写到我的浏览器中，我的结果是：http://localhost:9200/_cat/indices?v 我在 elasticsearch 中看不到 logstash 日志？弹性搜索中的logstash日志存储在哪里？ logstash.conf 看起来不错。但没有满意的结果。因此。我想通过logstash从C/logs/*.log下获取所有日志到弹性？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）：

首先你有几个配置问题：

• Elasticsearch 中的主机应该是一个数组（例如hosts => ["myHost:myPort3]），参见the doc
• Windows 上使用通配符的文件应使用正斜杠而不是反斜杠（请参阅this issue）
• 您的日期过滤器正在查找字段“logdate”，而它应该查找字段“TimeStamp”（给定您的日志文件）
• 为方便起见，我需要设置的一个设置是sincedb_path，因为 Logstash 不会尝试再次解析它已经解析的文件（它会检查 .sincedb 以查看它是否已经解析了一个文件，默认情况下位于 $HOME /.sincedb，您需要在使用相同日志文件进行测试时在解析之间将其删除）

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 {}
}
