Logstash日期使用日期过滤器解析为时间戳

Question

好吧,经过四处寻找,我无法找到问题的解决方案,因为它"应该"有效,但显然没有.我正在使用Ubuntu 14.04 LTS机器Logstash 1.4.2-1-2-2c0f5a1,我收到的消息如下:

2014-08-05 10:21:13,618 [17] INFO  Class.Type - This is a log message from the class:
  BTW, I am also multiline

在输入配置中,我有一个multiline编解码器,并且事件被正确解析.我还将事件文本分成几个部分,以便于阅读.

最后,我在Kibana中看到了类似下面的内容(JSON视图):

{
  "_index": "logstash-2014.08.06",
  "_type": "customType",
  "_id": "PRtj-EiUTZK3HWAm5RiMwA",
  "_score": null,
  "_source": {
    "@timestamp": "2014-08-06T08:51:21.160Z",
    "@version": "1",
    "tags": [
      "multiline"
    ],
    "type": "utg-su",
    "host": "ubuntu-14",
    "path": "/mnt/folder/thisIsTheLogFile.log",
    "logTimestamp": "2014-08-05;10:21:13.618",
    "logThreadId": "17",
    "logLevel": "INFO",
    "logMessage": "Class.Type - This is a log message from the class:\r\n  BTW, I am also multiline\r"
  },
  "sort": [
    "21",
    1407315081160
  ]
}

您可能已经注意到我放了一个";" 在时间戳中.原因是我希望能够使用时间戳字符串对日志进行排序,显然logstash并不是那么好(例如:http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/ multi-fields.html).

我没有成功尝试过date多种方式使用过滤器,显然它没有用.

date {
            locale => "en"
            match => ["logTimestamp", "YYYY-MM-dd;HH:mm:ss.SSS", "ISO8601"]
            timezone => "Europe/Vienna"
            target => "@timestamp"
            add_field => { "debug" => "timestampMatched"}
        }

因为我读到Joda库可能会遇到问题,如果字符串不是严格符合ISO 8601标准(非常挑剔并期待T,请参阅https://logstash.jira.com/browse/LOGSTASH-180),我也尝试过用于mutate将字符串转换为类似2014-08-05T10:21:13.618然后使用"YYYY-MM-dd'T'HH:mm:ss.SSS".这也行不通.

我不想在时间上手动输入+02:00,因为这会给夏令时带来问题.

在任何一种情况下,事件进入elasticsearch,但date确实显然没有,因为@timestamp和logTimestamp是不同的,没有debug加场.

知道如何让logTime字符串正确排序吗？我专注于将它们转换为适当的时间戳,但任何其他解决方案也将受到欢迎.

如下所示:

当排序过@timestamp,elasticsearch可以做正确,但由于这是不是"真正的"日志时间戳,而是当读取的logstash事件,我需要(明显),以便能够在同时进行排序logTimestamp.这就是输出.显然没那么有用:

欢迎任何帮助!如果我忘记了一些可能有用的信息,请告诉我.

这是最终工作的过滤器配置文件:

# Filters messages like this:
# 2014-08-05 10:21:13,618 [17] INFO  Class.Type - This is a log message from the class:
#  BTW, I am also multiline

# Take only type- events (type-componentA, type-componentB, etc)
filter {
    # You cannot write an "if" outside of the filter!
    if "type-" in [type] {
        grok {
            # Parse timestamp data. We need the "(?m)" so that grok (Oniguruma internally) correctly parses multi-line events
            patterns_dir => "./patterns"
            match => [ "message", "(?m)%{TIMESTAMP_ISO8601:logTimestampString}[ ;]\[%{DATA:logThreadId}\][ ;]%{LOGLEVEL:logLevel}[ ;]*%{GREEDYDATA:logMessage}" ]
        }

        # The timestamp may have commas instead of dots. Convert so as to store everything in the same way
        mutate {
            gsub => [
                # replace all commas with dots
                "logTimestampString", ",", "."
                ]
        }

        mutate {
            gsub => [
                # make the logTimestamp sortable. With a space, it is not! This does not work that well, in the end
                # but somehow apparently makes things easier for the date filter
                "logTimestampString", " ", ";"
                ]
        }

        date {
            locale => "en"
            match => ["logTimestampString", "YYYY-MM-dd;HH:mm:ss.SSS"]
            timezone => "Europe/Vienna"
            target => "logTimestamp"
        }
    }
}

filter {
    if "type-" in [type] {
        # Remove already-parsed data
        mutate {
            remove_field => [ "message" ]
        }
    }
}

我测试了你的date过滤器.它适用于我!

这是我的配置

input {
    stdin{}
}

filter {
    date {
        locale => "en"
        match => ["message", "YYYY-MM-dd;HH:mm:ss.SSS"]
        timezone => "Europe/Vienna"
        target => "@timestamp"
        add_field => { "debug" => "timestampMatched"}
   }
}

output {
    stdout {
            codec => "rubydebug"
    }
}

我用这个输入:

2014-08-01;11:00:22.123

输出是:

{
   "message" => "2014-08-01;11:00:22.123",
  "@version" => "1",
"@timestamp" => "2014-08-01T09:00:22.123Z",
      "host" => "ABCDE",
     "debug" => "timestampMatched"
}

因此,请确保您logTimestamp的值正确.这可能是其他问题.或者您可以提供日志事件和logstash配置以进行更多讨论.谢谢.
