使用logstash將csv文件導入elasticsearch時出錯

Question

我想使用logstash將一個csv文件導入Logsearch。 我的代碼如下

    input {
file {
path =>"C:\Users\welcome\Dropbox\IT_Department\BigDataProjects\StudentWithdraElastic\student_withdraw.csv"
start_position => "beginning"
sincedb_path => "j:\null"
}
}
filter {
csv {
separator => ","
columns => ["DEPT_NAME" ,"CERT_NAME",   "SPEC_NAME" ,"STUDENT_NO",  "STUD_NAME",    "GENDER",   "ADVISORS_NAME",    "ACADEMIC_YEAR",    "REQUEST_NO",
        "withdraw_reason_category", "STATUS",   "WITHDRAW_DATE",    "LECTURER", "COURSE_NO",    "COURSE_NAME",  "SECTION_NO",   "TOTAL_REG"]
    mutate {convert => ["SECTION_NO", "integer"] }
    mutate {convert => ["TOTAL_REG", "integer"] }

}
output { 
 elasticsearch {
  hosts => "https://hadoop.hct.org"
  index => "withDrawIndex"
  document_type => "studentWithdrawDocument"
  }
  stdout {}
  }

我用以下命令運行它

C:\Elastic\logstash-6.2.2>bin\logstash -f C:\Users\welcome\Dropbox\IT_Department\BigDataProjects\StudentWithdraElastic\logstash_withdraw.config

它給出了以下錯誤

Sending Logstash's logs to C:/Elastic/logstash-6.2.2/logs which is now configured via log4j2.properties

我搜索了解決方案，但沒有找到任何可以幫助的方法。

您在csv過濾器的末尾缺少右花括號：

filter {
  csv {
    separator => ","
    columns => ["DEPT_NAME" ,"CERT_NAME",   "SPEC_NAME" ,"STUDENT_NO",  "STUD_NAME",    "GENDER",   "ADVISORS_NAME",    "ACADEMIC_YEAR",    "REQUEST_NO", "withdraw_reason_category", "STATUS",   "WITHDRAW_DATE",    "LECTURER", "COURSE_NO",    "COURSE_NAME",  "SECTION_NO",   "TOTAL_REG"]
  }                                                <-- this is missing
  mutate {convert => ["SECTION_NO", "integer"] }
  mutate {convert => ["TOTAL_REG", "integer"] }
}
