大家用过redis，不知道用没用过codis，根据codis做了一个调用关系图，可以明确知道谁在使用codis。 结果会显示哪个IP地址在请求哪个codis集群
- running inside Mac
- go1.14.6
- 查询codis链接 --- 提供http的一个接口，可以查询codis的调用关系
- 定时获取codis集群信息 --- 通过codis-fe页面地址，抓取codis的所有集群信息
- 定时获取codis链接信息 --- 通过读取es数据，处理链接信息并存储mysql数据库
- filebeat-7.6.1 --- 收集codis的proxy日志信息
- kafka 2.1.1 --- 充当消息队列
- logstash 6.8.0 --- 解析codis信息处理并存入ES
- Elasticsearch 6.8.0 --- 存储所有的codis链接信息
- mysql 8.0.21 --- 存储codis集群信息，以及处理后的链接信息
- 修改yaml下的config.yaml配置文件
local 下的 codisurl 配置为codis的fe页面地址，其中estimediff为获取es数据的时间间隔，单位s
mysql 下的链接配置
elasticsearch 下的链接配置
- 所有codis的proxy节点都要配置filebeat，收集proxy信息，下面是参考配置
/etc/filebeat/filebeat.yml 文件内容如下
filebeat.config.inputs:
enabled: true
path: /etc/filebeat/input.conf.d/*.yml
reload.enabled: true
reload.period: 10s
filebeat.inputs:
- type: log
enabled: false
paths:
- /var/log/*.log
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.template.settings:
index.number_of_shards: 3
setup.kibana:
processors:
- add_host_metadata:
netinfo.enabled: true
- drop_fields:
fields: ["beat.hostname","prospector.type","beat.version","beat.name","agent.ephemeral_id", "agent.hostname", "agent.id", "agent.type", "agent.version", "ecs.version", "input.type", "log.offset", "version"]
output.kafka:
hosts: ["172.30.1.2:9092"]
topic: '%{[fields.log_topic]}'
partition.hash:
reachable_only: false
hash: ["host", "log.file.path"]
required_acks: 1

max_message_bytes: 1000000
output.elasticsearch:

max_procs: 1
/etc/filebeat/input.conf.d/codis-proxy.yml 文件
- type: log
enabled: true
paths:
- /data/codis-proxy/logs/codis-proxy.log
ignore_older: 1h
fields:
log_topic: codis-proxy-log
- 使用logstash消费kafka，处理信息，并写入ES，下面是参考配置

group_id => "logstash-codis"

}
mutate {

}
}else{

add_field => ["clientip", "%{remote[0]}"]
}
mutate {
add_field => ["codisname", "%{[host][name]}"]
}
mutate {
add_field => ["codisip", "%{[host][ip][0]}"]
}
mutate {
remove_field => ["host","message","create","ops","type","lastop","remote","logdate","jsondata","log_level","cmdfile","cmdxxx","cmdnum"]
}
}
