缘起

最近在使用腾讯云,想对访问日志进行收集与分析,发现CLB(负责均衡)日志只能保存到COS上面,而且是每个CLB没小时压发送个gz压缩包到COS。

实现方式

CLB配置日志存储到COS,Filebeat客户端CVM安装cosfs挂载COS,并配置Filebeat输出到Elasticsearch集群,最后通过Kibana和Grafana分析。

参考文档

/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-elasticsearch-9.2.0-java/lib/logstash/outputs/elasticsearch/elasticsearch-template-es6x.json

实施步骤

1. COS创建bucket用于存储CLB日志
2. CLB配置存储日志到COS

日志访问:当前仅支持HTTP/HTTPS访问日志的收集,腾讯云默认在CLB底层为客户保留3天的日志;开启日志访问后,日志将存入COS,支持更长期地存储,详情请见https://cloud.tencent.com/document/product/214/10329。

3. 客户端配置COSFS工具

安装Filebeat或Logstash客户端上安装COSFS工具,挂载COS,安装参考https://cloud.tencent.com/document/product/436/6883。

4. 客户端配置传输日志到Elasticsearch集群

a. Logstash主要配置信息如下:

input {
   file{
      path => "/nginxlog/clb_log_bj/*/*/*"   #监控日志路径,可通配
      exclude => "*.gz"                              #排除掉gz压缩文件,因为腾讯CLB日志没小时生成一个压缩包,这边需要脚本自动解压缩
      codec => "json"                                #日志格式为JSON
   }
}

filter {
    jdbc_streaming{                          #使用jdbc_streaming filter是给域名加上部门,默认CLB日志没有部门字段,也可以用translate filter但是不方便动态更新
        jdbc_driver_library => "/etc/logstash/mysql-connector.jar"
        jdbc_driver_class => "com.mysql.jdbc.Driver"
        jdbc_connection_string => "jdbc:mysql://localhost:3306/domain"
        jdbc_user => "domain_rw"
        jdbc_password => "domain_password"
        statement => "select ifnull((select department from domain.domain WHERE url = :server_name),CONVERT(‘其他‘ USING utf8)) as department"
        parameters => { "server_name" => "server_name"}
        target => "department"
    }
}

output {
   elasticsearch {
       hosts => ["elasticsearch01:9200","elasticsearch02:9200","elasticsearch03:9200"]
       index => "logstash-nginxlog-%{+YYYY.MM.dd}"
       manage_template => true
       template_overwrite => true
       template_name => "nginx_template"                                 #自定义模板名字
       template => "/etc/logstash/templates/nginx_template"      #自定义模板路径
  }
}

b. Nginx模板配置信息如下:

{
"template" : "logstash-nginxlog-*",     #在默认logstash模板上面修改的
"version" : 999,
"settings" : {                                       #主要是改动index分片,副本,其他也可以更加需要修改
"index.refresh_interval" : "60s",
"index.number_of_shards": "3",
"index.number_of_replicas": "1"
},
"mappings" : {
"_default_" : {
"dynamic_templates" : [ {
"message_field" : {
"path_match" : "message",
"match_mapping_type" : "string",
"mapping" : {
"type" : "text",
"norms" : false
}
}
}, {
"string_fields" : {
"match" : "*",
"match_mapping_type" : "string",
"mapping" : {
"type" : "text", "norms" : false,
"fields" : {
"keyword" : { "type": "keyword", "ignore_above": 256 }
}
}
}
} ],
"properties" : {
"@timestamp": { "type": "date"},
"@version": { "type": "keyword"},
"geoip" : {
"dynamic": true,
"properties" : {
"ip": { "type": "ip" },
"location" : { "type" : "geo_point" },
"latitude" : { "type" : "half_float" },
"longitude" : { "type" : "half_float" }
}
}
}
}
}
}

c. Filebeat主配置文件如下:

filebeat.inputs:                          #默认简单需求filebeat就能满足,记录下
- type: log
enabled: true
paths:
- /nginxlog/clb_log_bj/*/*/*        #监控日志路径

exclude_files: [‘.gz/pre>]          #排除压缩文件

json.message_key: log            #如下三行设置json格式
json.keys_under_root: true
json.overwrite_keys: true

filebeat.config.modules:           #设置日志字段,可以删除不需要的字段信息
path: ${path.config}/modules.d/*.yml
reload.enabled: true

setup.template.enabled: true    #如下设置索引名称、分片、副本信息
setup.template.name: "filebeat-nginxlog"
setup.template.pattern: "filebeat-nginxlog-*"
setup.template.overwrite: true
setup.template.settings:
index.number_of_shards: 3
index.number_of_replicas: 1

output.elasticsearch:                 #如下输出elasticsearch集群配置
hosts: ["elasticsearch01:9200","elasticsearch02:9200","elasticsearch03:9200"]
index: "filebeat-nginxlog-%{+yyyy.MM.dd}"
5. Grafana或者Kibana制图

a. Grafana制图模板如下:
