前言

本文使用的系统为 Arch Linux 部分包可能在您的系统不存在/低版本

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
