篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用ELK分析腾讯云CLB日志相关的知识，希望对你有一定的参考价值。
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
