<configuration>
<appender name="stash" class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>info</level>
</filter>
<file>/some/path/to/your/file.log</file>
<encoder class="net.logstash.logback.encoder.LogstashEncoder" />
</appender>
<root level="all">
<appender-ref ref="stash" />
</root>
</configuration>Use it in your logstash configuration like this:
input {
file {
type => "your-log-type"
path => "/some/path/to/your/file.log"
format => "json_event"

}
