Prometheus的配置

scrape_configs:
    - job_name: 'consul-node'
      consul_sd_configs:
      - server: '172.16.154.13:8500'
        tags:
        - "nodes"
        refresh_interval: 5s

consul中的配置

API形式注册，consul reload 也不会去掉api形式的注册。即使文件中没有下面这个节点的信息

curl -X PUT -d '{"id": "node04","name": "nodes","address": "172.16.110.14","port": 9101,"tags": ["nodes"],"checks": [{"http": "http://172.16.110.14:9101/metrics", "interval": "5s"}]}'  http://172.16.110.10:8500/v1/agent/service/register
