Field have the same value

[Dea_Agra]

I don't know why logstash keep parsing the same value for the different field.

Here I attach my logstash configuration

input {
file {
start_position => "beginning"
sincedb_path => "/dev/null"
path => [ "/home/elasticsearch/logstash-7.10.0/data/tomcat.log"]
type => "tomcat"
codec => multiline {
      pattern => "^\s"
      what => "next"
}

}
}

filter {
if [type] == "tomcat" {
grok {
break_on_match => false
  match => [
    "message", "%{URIPATH:request}",
    "message", "%{NOTSPACE:available_pattern}",
    "message", "%{QS:agent}",
    "message", "%{WORD:method}",
    "message", "%{NOTSPACE:type}",
    "message", "%{NOTSPACE:referrer}",
    "message", "%{NOTSPACE:source-type}",
    "message", "%{NUMBER:size}",
    "message", "%{NUMBER:responseTime}",
    "message", "%{NOTSPACE:host}",
    "message", "%{IP:client}",
    "message", "%{NUMBER:timestamp}\n"
 ]
}

date {
  match => ["timestamp",
    "MMM dd HH:mm:ss",
    "MMM  d HH:mm:ss",
    "MMM dd yyyy HH:mm:ss",
    "MMM  d yyyy HH:mm:ss"
  ]
  timezone => "America/New_York"
}

 if "_grokparsefailure" not in [tags] {
     mutate {
      rename => ["tomcat_message", "message"]
     remove_field => ["timestamp"]
  }
 }
}
}

output {
 elasticsearch {
  index => "tomcat-sample5"
  hosts => ["192.168.1.10:9200"]
 }
}

the result

}

Can anyone pls help?

Your grok filter matches 12 patterns against the [message] field. But all of the patterns are independent. If you try to match the same pattern more than once, as you do with

"message", "%{NOTSPACE:type}",
"message", "%{NOTSPACE:referrer}",
"message", "%{NOTSPACE:source-type}",

then each one will match the same part of the message field, so it will result in the same value.

then what should I do?

[Dea_Agra]

I need them to be different and the value of the field match with the logs

A search of the forums should turn up examples of parsing tomcat logs using grok, such as this one.

but my logs look like this
