HI,  
I installed ELK 5.3 version.

When I start logstash to read the file for first time/even fresh file its not reading the data.

If I un-comment start\_position, then Logstash reading data. otherwise its not...

The following is the config,

input {  
file {  
path =\> "/var/log/tomcat/file.txt"

# start\_position =\> "beginning"

```
  sincedb_path => "/dev/null"
  ignore_older => 0

```

}  
}  
filter {  
grok {  
match =\> { "message" =\> "%{COMMONAPACHELOG}" }  
}  
}  
output {  
stdout { codec =\> rubydebug }  
elasticsearch {  
hosts =\> "IP"  
index =\> "logstash-%{+YYYY-MM-dd}"  
}  
}

Logstash running through command as follows,

./bin/logstash --path.settings /etc/logstash -f /path/Sample.conf

Please suggest if I miss anything

Thanks,  
Uday.K

Your `ignore_older => 0` setting tells the file input to ignore any files older than 0 seconds, which will basically be every file. This may explain the behavior you are seeing.

I recommend removing this setting.
