Not able to get Multiline logs in Grafana Loki from Logstash

[mohitk]

Hi, I am trying to ship my logs from logstash to Grafana loki. I got the single line logs from logstash to Loki but i am not getting multiline logs from logstash into Loki. is there any other configuration needs to be done for the same?

This is my logstash configuration

input {
beats {
host => “localhost”
port => “5044”
type => “log”
}
}

filter{
if ([fields][log_type] == “test”) {

    grok{
		match => [ "message" , "%{TIMESTAMP_ISO8601:date-time}" ]
	}
	
	grok{
		match => [ "message" , "%{GREEDYDATA:msg}" ]
	}
	
	grok{
		match => [ "message" , "\[com\] \[%{WORD:loglevel}\]" ]
 	}
	
	grok {
       match => {"message" => "\[08.%{DATA:classname}\]"}
    }   
	
	mutate {
        add_field => {
         "job" => "logstash"
        }
	}

}

}

output {
loki {
url => “http://localhost:3100/loki/api/v1/push”
}
stdout { codec => rubydebug{} }
}

This is my Loki configuration
