为什么我的grok过滤器不解析我的文件信号消息？我在Kibana（ELK）中看不到logstash解析的字段

Question

我已经配置了Filesbeat，它能够从syslog文件中提供的路径中读取新日志（现在为filebeat.yml），并将其转发到Logstash，然后它应将数据解析为[ C0]。

我在Kibana事件中的任何地方都看不到已解析的grok字段，例如syslog_timestamp，syslog_hostname，syslog_pid，我不知道为什么不解析数据的原因可能是什么。

Filebeat输入文件

Elasticearch

Grok筛选器（在Logstash中）

Kibana（Elasticsearch Json）

input{
        beats{
                port => "5044"
        }
}

filter {
        if[type] == "syslog"{
                grok{
                        match => {"message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}"}
                }
                date {
                        match => ["syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]
                }
        }
}

output{
        elasticsearch{
                hosts => ["10.107.50.205:9200"]
                index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
        }
}

设置已从版本6.0的Filebeat中删除，因为您正在使用Filebeat 7.3，所以此设置将被忽略，并且您的消息中没有document_type字段。

您需要使用type添加新字段并更改管道以基于该字段进行过滤。
