Consul服务发现 通过Consul可以动态注册监控服务，无需每次添加监控对象都重启Prometheus
下载Consul Donwload
解压并以WEB UI方式启动Consul # unzip consul_1.0.0_linux_amd64.zip # ./consul agent -server -ui -bootstrap-expect 1 -data-dir /tmp/consul -client 0.0.0.0 &
查看启动状态 # ./consul members Node Address Status Type Build Protocol DC Segment t-luhx01-v-szzb 10.0.139.161:8301 alive server 1.0.0 2 dc1 <all>
HTTP方式注册服务 # curl -X PUT -d '{"id":"mysql","name":"mysql","address":"10.0.139.163","port":9104,"tags":["test"],"checks":[{"http":"http://10.0.139.163.9104/","interval":"5s"}]}' http://localhost:8500/v1/agent/service/register
配置文件方式注册服务(/etc/consul.d/mysql.json) "service":{ "id": "mysql", "name": "mysql", "address": "10.0.139.162", "port": 9104, "tags": ["test"], "checks": [ { "http": "http://10.0.139.162:9104", "interval": "5s" } ] } }
修改Prometheus参数 global: scrape_interval: 15s evaluation_interval: 15s - job_name: prometheus static_configs: - targets: ['localhost:9090'] labels: instance: prometheus - job_name: 'consul' consul_sd_configs:p - server: 'localhost:8500' services: ['redis', 'mysql', 'linux']
指定文件启动 # ./consul agent -server -ui -bootstrap-expect 1 -data-dir /tmp/consul -config-dis /etc/consul.d -client 0.0.0.0 &
