默认开启的端口是3000
# 安装node_exporter
下载地址解压，运行即可。
默认开启的端口是9100。
需要手动在 prometheus server端配置上节点。
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['localhost:9090']
- job_name: 'nodes'
static_configs:
- targets:
- "106.12.xxx.xxx:9100"
- "106.15.xxx.xxx:9100"
- "121.42.xxx.xxx:9100"
- "122.152.xxx.xxx:9100"

# mysql监控
先在grafana里添加mysql的数据源。
将my2.sql文件导入数据库，https://github.com/john1337/my2Collector (opens new window)
用 https://grafana.com/grafana/dashboards/7991 (opens new window) 这个模版，最终展示即可。
# 最终效果
