帶有 mutate 的 Logstash JSON 過濾器以添加新字段

Question

我正在嘗試使用下面的 logstash 配置文件和過濾器從以下日志條目中獲取數據，但數據不是從 json 中獲取，而是顯示了 grok 模式。

日志：

13:41:37.3921 Info {"message":"CTS execution started","level":"Information","logType":"Default","timeStamp":"2019-12-03T13:41:37.3861868-05:00","fingerprint":"29dad848-4ff7-4d2d-905b-460637f3d534","windowsIdentity":"home","machineName":"L02174400","processName":"CTS","processVersion":"1.0.5","jobId":"5bbc492c-bcb7-451f-b6ac-87d9784ad00d","robotName":"home","machineId":0,"fileName":"SendBackReasons(Autosaved)"}

配置：

input{
    file{
        type => "executionlog"
        path => ["c:/users/xyj/appdata/local/uipath/logs/*[^W]_execution.log"]
            start_position => "beginning"
            sincedb_path => "c:/dbfile" 
              }
}

filter{
    grok{
        match => { "message" => ["(?<id>[\d\:\.]+)\s%{LOGLEVEL:level} %{GREEDYDATA:json-data}"]
              }
         }

    json{
        source => "json_data"
        target => "parsed_json"
            }
        mutate{
            add_field => {
                    "Info1" => "%{[json_data][message]}" #i tried parsed_json as well here
                    "level2" => "%{[json_data][level]}"

                    }
            }
    }
output{
    elasticsearch{
            hosts=>["http://localhost:9200"]
            index=> "uipathexecutionlog"
               }
               stdout{}
}

試試下面的代碼，

filter{
    grok{
        match => { "message" => ["(?<id>[\d\:\.]+)\s%{LOGLEVEL:level} %{GREEDYDATA:json-data}"]
              }
         }

    json{
        source => "json-data"
        target => "parsed_json"
            }
        mutate{
            add_field => {
                    "Info1" => "%{[parsed_json][message]}" 
                    "level2" => "%{[parsed_json][level]}"

                    }
            }
    }
