Logstash user-agent filter can't parse the user agent os with version

[chairxiao (dengcd)]

Hello,

My logstash's version is 7.7.1

I use the logstash user agent to parse the url,but i can't get the user agent os with version

I got the parse info as blow:

              "name" => "Firefox",
           "os_name" => "Windows",
          "original" => "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2) Gecko/20100115 Firefox/3.6",
             "minor" => "6",
                "os" => "Windows",
             "major" => "3",

I use the elasticsearch urldecode processor to parse the url

PUT _ingest/pipeline/user_agent
{
  "description" : "Add user agent information",
  "processors" : [
    {
      "user_agent" : {
        "field" : "agent"
      }
    }
  ]
}

PUT my_index/_doc/my_id?pipeline=user_agent
{
  "agent": "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2) Gecko/20100115 Firefox/3.6"
}

GET my_index/_doc/my_id

the result is

{
  "_index" : "my_index",
  "_type" : "_doc",
  "_id" : "my_id",
  "_version" : 1,
  "_seq_no" : 8,
  "_primary_term" : 1,
  "found" : true,
  "_source" : {
    "agent" : "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2) Gecko/20100115 Firefox/3.6",
    "user_agent" : {
      "original" : "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2) Gecko/20100115 Firefox/3.6",
      "os" : {
        "name" : "Windows",
        "version" : "XP",
        "full" : "Windows XP"
      },
      "name" : "Firefox",
      "device" : {
        "name" : "Other"
      },
      "version" : "3.6."
    }
  }
}

i check the elasticsearch file,it use the same regexes.yaml to parse the url with logstash.Why the result is defferent?

for the right parse is that:

"os" => "Windows XP"
