## 1.查看日志文件 kafka-dump-log.sh ##

<table> 
 <thead> 
  <tr> 
   <th>参数</th> 
   <th>描述</th> 
   <th>例子</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td><code>--deep-iteration</code></td> 
   <td></td> 
   <td></td> 
  </tr> 
  <tr> 
   <td><code>--files &lt;String: file1, file2, ...&gt;</code></td> 
   <td>必需; 读取的日志文件</td> 
   <td>–files 0000009000.log</td> 
  </tr> 
  <tr> 
   <td><code>--key-decoder-class</code></td> 
   <td>如果设置，则用于反序列化键。这类应实现kafka.serializer。解码器特性。自定义jar应该是在kafka/libs目录中提供</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td><code>--max-message-size</code></td> 
   <td>最大的数据量,默认：5242880</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td><code>--offsets-decoder</code></td> 
   <td>if set, log data will be parsed as offset data from the __consumer_offsets topic.</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td><code>--print-data-log</code></td> 
   <td>打印内容</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td><code>--transaction-log-decoder</code></td> 
   <td>if set, log data will be parsed as transaction metadata from the __transaction_state topic</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td><code>--value-decoder-class [String]</code></td> 
   <td>if set, used to deserialize the messages. This class should implement kafka. serializer.Decoder trait. Custom jar should be available in kafka/libs directory. (default: kafka.serializer. StringDecoder)</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td><code>--verify-index-only</code></td> 
   <td>if set, just verify the index log without printing its content.</td> 
   <td></td> 
  </tr>

**查询Log文件**

> `sh bin/kafka-dump-log.sh --files kafka-logs-0/test2-0/00000000000000000300.log`  
> ![在这里插入图片描述][e90ad7f1c39e5208120080475845dbb3.png]

**查询Log文件具体信息 `--print-data-log`**

> `sh bin/kafka-dump-log.sh --files kafka-logs-0/test2-0/00000000000000000300.log --print-data-log`  
> ![在这里插入图片描述][3306f80db58a943e6a59c39e66b4c4fe.png]

**查询index文件具体信息**

> `sh bin/kafka-dump-log.sh --files kafka-logs-0/test2-0/00000000000000000300.index`  
> ![在这里插入图片描述][bd918af516229bbb80640483831d6595.png]  
> 配置项为`log.index.size.max.bytes`； 来控制创建索引的大小;

**查询timeindex文件**

> `sh bin/kafka-dump-log.sh --files kafka-logs-0/test2-0/00000000000000000300.timeindex`  
> ![在这里插入图片描述][2254d080ca4e63d13714b40b6c0c3b63.png]
