Question

我的日志文件有多个模式，包括JSON格式的日志。我想在grok插件中解析多个模式，但它似乎没有工作。

'filter {grok {  break_on_match => false 
match =>[ "message", "%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadID} - %{GREEDYDATA:Line}",
           "message","%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadID} - %{IP:Clicnet} - - %{GREEDYDATA:Line}"]}
           json {source => "Line"}mutate{remove_field => [ "Line","ThreadID" ]}}'

即使成功解析了JSON字符串的行，也有grokparsefailure标记。

2017-01-27 11:54:48 INFO PropertiesReader：33 - {“timestamp”：1485518878968，“h”：“297268184dde”，“l”：“INFO”，“cN”：“org .com.logstash.demo“，”mN“：”loadProperties“，”m“：”从/ var / tmp / conf加载属性文件“}

{
       "message" => "2017-01-27 11:54:48 INFO PropertiesReader:33 - {\"timestamp\":1485518878968,\"h\":\"297268184dde\", \"l\":\"INFO\", \"cN\":\"org.com.logstash.demo\", \"mN\":\"loadProperties\", \"m\":\"load property file from /var/tmp/conf\"}",
      "@version" => "1",
    "@timestamp" => "2017-03-20T17:19:16.316Z",
          "type" => "stdin",
          "host" => "ef3b82",
       "LogDate" => "2017-01-27 11:54:48",
      "loglevel" => "INFO",
    "threadName" => "PropertiesReader",
          "tags" => [
        [0] "_grokparsefailure"
    ],
     "timestamp" => 1485518878968,
             "h" => "297268184dde",
             "l" => "INFO",
            "cN" => "org.com.logstash.demo",
            "mN" => "loadProperties",
             "m" => "load property file from /var/tmp/conf"
}

和没有JSON的第二行完全失败

       "LogDate" => [

        [1] "2017-01-20 15:46:16"
    ],
      "loglevel" => [
        [0] "INFO",
        [1] "INFO"
    ],
    "threadName" => [
        [0] " RequestLog",
        [1] " RequestLog"

       "Clicnet" => "10.252.134.34",
          "tags" => [
        [0] "_jsonparsefailure"
    ]
}

花了5个小时后，我设法找到了解决方案。在下面用于成功解析两个日志行的模式

/opt/logstash/bin/logstash -e 'filter {grok  { match =>{ "message" =>["%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadName} - %{IP:Client} - - %{GREEDYDATA:LogMessage}", "%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} (?<threadName>[^:]+):%{NUMBER:ThreadID} - %{GREEDYDATA:Line}"]}}  json {source => "Line"} mutate{remove_field => [ "Line","ThreadID" ]}}'

要在Logstash中解析的多个模式
