安装 Prometheus 和 Grafana

sudo pacman -S prometheus grafana

配置 Grafana

1) 由于 Prometheus 的默认配置足够监控本机，因此不进行配置，但仍放出配置文件

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).
 
# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093
 
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"
 
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
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: ["127.0.0.1:9090"]

2) 启动服务

sudo systemctl enable prometheus grafana --now

3) 登陆 Grafana

地址为 :3000 ，默认帐号密码 admin/admin 登陆会有要求设置新密码

4) 添加图表

在登陆后点击 Add new connection 搜索到 Prometheus

进入后点击 Add new data source ，在 HTTP 栏填入 http://127.0.0.1:9090 即 Prometheus 监听地址，在 Other 中更改 HTTP method 从 POST 改为 GET，最后点击 Save & test

保存后点击最上方的 Dashboards，从三个中随便选一个导入

回到 Dashboards 即可查看监控
