Hi Everyone !,

So what I'm going to do is indexing .log data with grok using logstash, but in the middle of indexing, it's suddenly stopped. I am already using --debug flag to see what's going on, and it keeps loop this message

**[2021-06-18T17:55:39,974][DEBUG][logstash.instrument.periodicpoller.cgroup] One or more required cgroup files or directories not found: /proc/self/cgroup, /sys/fs/cgroup/cpuacct, /sys/fs/cgroup/cpu**  
**[2021-06-18T17:55:40,131][DEBUG][logstash.instrument.periodicpoller.jvm] collector name {:name=\>"ParNew"}**  
**[2021-06-18T17:55:40,131][DEBUG][logstash.instrument.periodicpoller.jvm] collector name {:name=\>"ConcurrentMarkSweep"}**  
**[2021-06-18T17:55:41,099][DEBUG][org.logstash.execution.PeriodicFlush][main] Pushing flush onto pipeline.**

Here's my simple config file

```auto
input{
    file{
        path => ["E:/Belajar Ngoding/Elasticsearch/Hadoop.log"]
        start_position => "beginning"
        sincedb_path => "NUL"
    }
}
filter{
    grok{
        match => {"message" => [' %{DATESTAMP:Time} %{LOGLEVEL:logLevel} %{LOGLEVEL:logMain} {%GREEDYDATA:logMessage}'] }
    }
}
output{
    elasticsearch{
        hosts => "http://localhost:9200"
        index => "HadoopLog"

        user => "elastic"
        password => "sigh"
    }
    stdout{}
}

```

Can someone tell me what am i doing wrong ? Thanks 🙂
