我有一个日志被捕获并发送到logstash,日志的格式是
22304999 5 400.OUTPUT_SERVICE.510 submit The limit has been exceeded. Please use a different option. 2.54.44.221 /api/output/v3/contract/:PCID/order /api/output/v3/contract/:pcid/order https://www.example.org/output/ PUT 400 2017-09-28T15:50:57.843176Z
我正在尝试创建一个自定义grok过滤器,以便在将头字段发送到elasticsearch之前添加它们。
我的目标是这样的,
SessionID => "22304999"
HitNumber => "5"
FactValue => "400.OUTPUT_SERVICE.510"
DimValue1 => "submit"
ErrMessage => "The limit has been exceeded. Please use a different option."
IP => "2.54.44.221"
TLT_URL => "/api/output/v3/contract/:PCID/order"
URL => "/api/output/v3/contract/:pcid/order"
Refferer => "https://www.example.org/output/"
Method => "PUT"
StatsCode => "400"
ReqTime => "2017-09-28T15:50:57.843176Z"
我是新手,所以只是试图理解我如何应用并测试它,例如我会从一个空滤镜开始,
filter {
grok {
match => { "message" => "" }
}
}
我的第一个问题是match => { "message" => "" }
消息只是一个日志行吗?什么定义'消息'?
我的日志和我想要的字段用Tab分隔,在每个Tab之后它是一个新字段,这会使我想要实现的更容易,而不是寻找模式我可以只查找下一个标签吗?
如果做不到这一点,有人可以为我的一个领域提供一个例子,我应该可以完成其余的工作。

正则表达式:(?<SessionID>\S+)\s+(?<HitNumber>\S+)\s+(?<FactValue>\S+)\s+(?<DimValue1>\S+)\s+(?<ErrMessage>.+)\s+(?<IP>(?:\d{1,3}\.){3}\d{1,3})\s+(?<TLT_URL>\S+)\s+(?<URL>\S+)\s+(?<Refferer>\S+)\s+(?<Method>\S+)\s+(?<StatsCode>\S+)\s+(?<ReqTime>\S+)
