I've a logstash configuration file which contains ruby code.  
**How can I script the ruby part of the logstash filter in ingest pipeline?**

It's a server with filebeat.  
All part except the ruby code I "moved" into the ingest pipline definition.

**my\_logstash.conf**

filter {  
csv {  
columns =\> ['BL','MA',OffsetByte,'LengthByte']  
separator =\> ";"  
autogenerate\_column\_names =\> false  
}  
mutate {  
add\_field =\> { "my\_stats" =\> "%{path}" }  
convert =\> {  
"LengthByte" =\> "integer"  
}  
}  
**ruby** {  
code =\> "  
stats = IO.read(event.get('my\_stats'), event.get('LengthByte'), event.get('OffsetByte') )  
linecount = stats.scan(/\n/).count  
event.set('Statistics', stats[0..-(linecount+1)])  
"  
}

}  
}

Ingest node pipelines do not support Ruby, so the only way I can think of would be to try and move this logic into a painless script.

I'll give a try

"filters": [  
{  
"ruby": {  
"code": "stats = IO.read(event.get('path\_stats'), event.get('LengthByte'),event.get('OffsetByte')) linecount = stats.scan(/\n/).count event.set('Statistics', stats[0..-(linecount+1)])"  
}  
}  
],

later more, when tested

IO.read -\> cannot access Input file via Pipeline, so this is not a solution
