I used codes below in ABC.conf file which i use in a way that "/usr/share/logstash/bin/logstash -f ./ABC.conf "

filter{  
csv{  
separator =\>","  
columns =\>   
}

}

and columns are auto generated and named as it says like that

however those auto-generated columns aren't usable... Does anyone know how to use it??

Machine Learning will not work with fields that are arrays. If you want ML to work with multiple metrics, format your data similarly to the example shown here:
