filebeat+logstash对springcloud项目日志进行解析
项目地址：https://gitee.com/lwydyby/springcloud-adplatform
该项目的日志目前可以分为三种：
(1)项目启动日志
(2)controller层的操作日志（通过aop实现记录）
(3)项目非controller层异常日志
由于分为3种格式，则需要三种macth进行匹配：
grok {
match => ["message","%{TIMESTAMP_ISO8601:timestamp} \[%{NOTSPACE:thread}\] %{WORD:type} com.gameley.common.Interceptor.HttpAspect - %{GREEDYDATA:log_json}",
"message","%{TIMESTAMP_ISO8601:timestamp} \[%{NOTSPACE:thread}\] %{WORD:type} %{NOTSPACE:classname} \- (?[\s\S]*)" ,
"message","%{TIMESTAMP_ISO8601:timestamp} \[%{NOTSPACE:thread}\] %{WORD:type} %{NOTSPACE:classname} \- %{GREEDYDATA:otherinfo}" ]
} 使用logstash自带表达式的格式一般为：%{SYNTAX:SEMANTIC}
即： SYNTAX代表匹配值的类型，例如，0.11可以NUMBER类型所匹配，10.222.22.25可以使用IP匹配。 SEMANTIC
*表示存储该值的一个变量声明，client_ip_address`这个字段里边，类似数据库的列名
具体可参考：http://blog.csdn.net/liukuan73/article/details/52318243
而自定义匹配需要使用正则表达式，格式为
( ?<列名>正则表达式)注：[\s\S]*为匹配剩余所有的字符，我这里是用来匹配错误日志的详细信息的
由于controller层日志是以json格式进行的存储，除使用grok之外还需使用 json进行解析
json {
source => "log_json"
target => "content"
remove_field=>["logjson"]
} 完整配置文件为：
input {
beats {
port => 5044
}
}
filter{
grok {
match => ["message","%{TIMESTAMP_ISO8601:timestamp} \[%{NOTSPACE:thread}\] %{WORD:type} com.gameley.common.Interceptor.HttpAspect - %{GREEDYDATA:log_json}",
"message","%{TIMESTAMP_ISO8601:timestamp} \[%{NOTSPACE:thread}\] %{WORD:type} %{NOTSPACE:classname} \- (?[\s\S]*)" ,
"message","%{TIMESTAMP_ISO8601:timestamp} \[%{NOTSPACE:thread}\] %{WORD:type} %{NOTSPACE:classname} \- %{GREEDYDATA:otherinfo}" ]
}
json {
source => "log_json"
target => "content"
remove_field=>["logjson"]
}
}
output {
elasticsearch {
hosts => ["localhost"]
manage_template => false
index => "%{[fields][logIndex]}-%{+YYYY.MM.dd}"
document_type => "%{[fields][docType]}"
}
}除需要配置logstash之外，还需要对filebeat进行配置，以设置如何发送日志（处理多行日志）：
filebeat:
prospectors:
-
paths:
- "/data/logs/*.log"
fields:
logIndex: userservice
docType: springcloud
project: adplatform
multiline:
pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
negate: true
match: after
timeout: 5s
output:
logstash:
hosts: ["localhost:5044"]日志文件样例：
