输入是以下消息文本:
@ConditionOnProperty(prefix="status.", value="host", havingValue=System.getProperty("hostName") // property set elsewhere
这是我的logstash配置的过滤器部分:
@ConditionalOnProperty
然后我的时间戳如下:
{"timestamp":"2018-08-02 15:56:46,569","level":"DEBUG","class":"classname","method":"run","line":"730","thread":"threadname","message":"messagetext"}
并且我无法删除/擦除“:”的首次出现。 我已经尝试过
filter {
if "pattern_09" in [tags] {
mutate {
gsub => [ "message" , "{" , "",
"message" , "}" , "" ] }
dissect {
mapping => { "message" => "%{Timestamp},%{+Timestamp/2},%{level},%{class},%{method},%{line},%{thread},%{mymessage}"}
}
mutate {
gsub => [ "Timestamp" , "timestamp", "",
"Timestamp" , "\"", "" ,
"level" , "level" , "" ,
"level" , ":", "" ,
"level" , "\"", "" ,
"class" , "class" , "" ,
"class" , ":", "" ,
"class" , "\"", "" ,
"method" , "method" , "" ,
"method" , ":", "" ,
"method" , "\"", "" ,
"line" , "line" , "" ,
"line" , ":", "" ,
"line" , "\"", "" ,
"thread" , "thread" , "" ,
"thread" , ":", "" ,
"thread" , "\"", "" ,
"mymessage" , "mymessage" , "" ,
"mymessage" , ":", "",
"mymessage" , "\"", "" ]
}
date {
match => [ "Timestamp", "yyyy-dd-MM HH:mm:ss,SSS" ]
}
}
}
但这没有效果。

为什么不使用grok
过滤器?这样的模式匹配要方便得多。
对于上面的示例,可以按以下步骤完成
grok {
match => ["message" ,'%{GREEDYDATA}"timestamp":"%{DATA:Timestamp}"%{GREEDYDATA}"level":"%{DATA:Level}"%{GREEDYDATA}"class":"%{DATA:Class}"%{GREEDYDATA}"method":"%{DATA:Method}"%{GREEDYDATA}"line":"%{DATA:Line}"%{GREEDYDATA}"thread":"%{DATA:Thread}"%{GREEDYDATA}"message":"%{DATA:Message}"%{GREEDYDATA}']
}
date {
match => [ "Timestamp", "yyyy-dd-MM HH:mm:ss,SSS" ]
}
DATA
和GREEDYDATA
只是模式,我们可以在这里使用更多的模式:https://github.com/logstash-plugins/logstash-patterns-core/tree/master/patterns
这里有更多关于grok过滤器的信息:https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html,您可以在这里测试您的grok模式:https://grokdebug.herokuapp.com/
