Hi.  
I use logback (file appender, time-based policy, hourly) and logstash send to kafka from logback result.  
But when file is rolling, logstash miss some first lines.  
I guess that inode in sincedb file is reuse.

Please tell me How I solve this problem? (ignore\_older? sincedb\_clean\_after? filebeat?)

below (my logback config):

> 

```
<file>logs/current.log</file>
<encoder>
    <pattern>%d{yyyyMMdd}\t%d{HHmmssSSS}\t%m%n</pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <fileNamePattern>logs/log_%d{yyyyMMdd,aux}/story_contents.%d{yyyyMMddHH}.log</fileNamePattern>
    <maxHistory>2</maxHistory>
</rollingPolicy>

```

below (my logstash config) :

> input {  
> file {  
> type =\> "xxx"  
> path =\> ["/path"]  
> start\_position =\> "beginning"  
> sincedb\_write\_interval =\> 1  
> }  
> }
