prometheus protmetheus+grafana+alert+consul框架安装exporter
prometheus exporter安装
适用于prometheus+grafana+alert+consul的架构
详情需要根据自己的实际情况修改
docker-exporter
这个适用于 prometheus+consul+prometheus+grafana，安装文档请参考这个文档
运行docker-exporter
//在需要监控的机器上执行
docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:ro \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--volume=/dev/disk/:/dev/disk:ro \
--publish=8080:8080 \
--detach=true \
--name=cadvisor \
--privileged \
--device=/dev/kmsg \
google/cadvisor
//容器启动没有问题后，可以访问地址查看监控指标是否收集到。比如我此时安装docker收集器的服务器地址为192.168.2.184，那么访问的地址就是http://192.168.2.184:8080/mertics
向consul注册
编写向consul注册的请求体文件consul-node.json
vim consul-node.json
{
"ID": "docker-exporter-192.168.2.184",
"Name": "docker-exporter-192.168.2.184",
"Tags": [
"docker-exporter"
],
"Address": "192.168.2.184",
"Port": 8080,
"Meta": {},
"EnableTagOverride": false,
"Check": {
"HTTP": "http://192.168.2.184:8080/metrics",
"Interval": "10s"
},
"Weights": {
"Passing": 10,
"Warning": 1
}
}
使用rest请求向consul进行注册
curl --request PUT --data @consul-node.json http://192.168.2.184:8500/v1/agent/service/register?replace-existing-checks=1
调用成功后，可以登陆consul的页面查看应用是否注册成功
配置prometheus
如果是第一次在prometheus添加此种类型的收集器，编辑prometheus配置文件prometheus.yml，添加如下配置
- job_name: 'consul-docker-exporter'
consul_sd_configs:
- server: '192.168.2.184:8500'
services: []
relabel_configs:
- source_labels: [__meta_consul_tags]
regex: .*docker-exporter.*
action: keep
- source_labels: [ __meta__consul_service ]
target_label: instance
添加配置后，调用接口热加载prometheus
curl -X POST http://localhost:9090/-/reload
配置grafana
如果是第一次添加此种类型的收集器，需要配置grafana。
选择存储数据库，然后点击import

最终效果
下线服务
注册后，想要下线服务，可以通过调用consul接口的方式，执行下线操作
//docker-exporter-192.168.2.184是consul-node.json中的ID属性
curl -X PUT http://192.168.2.184:8500/v1/agent/service/deregister/docker-exporter-192.168.2.184
