安装prometheus后配置文件配置(prometheus.yml):

# my global config
global:
  scrape_interval:     5s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 5s # 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: ['172.16.0.5:9093']
      #- 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:
  - job_name: 'prometheus-basic'
    static_configs:
    - targets: ['172.16.0.1:9100']
    - targets: ['172.16.0.2:9100']
    - targets: ['172.16.0.3:9100']
    - targets: ['172.16.0.4:9100']
    - targets: ['172.16.0.5:9100']
    - targets: ['172.16.0.6:9100']

  - job_name: 'nacos-prometheus'
    metrics_path: '/nacos/actuator/prometheus'
    file_sd_configs:
    - files: ['/usr/local/env/prometheus/prometheus-2.16.0.linux-amd64/config/nacos*.yml']
      refresh_interval: 5s

  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'redis-prometheus'
    metrics_path: '/metrics'
    file_sd_configs:
    - files: ['/usr/local/env/prometheus/prometheus-2.16.0.linux-amd64/config/redis*.yml']
      refresh_interval: 5s

  - job_name: 'pushgateway'
    static_configs:
    - targets: ['172.16.0.5:9091']

  - job_name: 'log2prometheus'
    static_configs:
    - targets: ['172.16.0.5:4007']


  - job_name: 'app-prometheus'
    metrics_path: '/actuator/prometheus'
    basic_auth: 
      username: 'admin'
      password_file: '/usr/local/env/prometheus/prometheus-2.16.0.linux-amd64/config/basic-auth-password'
    file_sd_configs:
    - files: ['/usr/local/env/prometheus/prometheus-2.16.0.linux-amd64/config/app*.yml']
      refresh_interval: 5s

动态应用配置:

- labels:
    service: wechat-auth
  targets:
  - 172.16.0.1:9088
  - 172.16.0.2:9088
- labels:
    service: clerk
  targets:
  - 172.16.0.1:9086
  - 172.16.0.2:9086
- labels:
    service: wx
    __metrics_path__: /wx/actuator/prometheus
  targets:
  - 172.16.0.1:9097
  - 172.16.0.2:9097
- labels:
    service: pay-account
  targets:
  - 172.16.0.1:9095
  - 172.16.0.2:9095

快捷启动shell(start.sh):

#!/bin/bash
nohup ./prometheus --web.enable-lifecycle  --web.listen-address=:9996 --config.file=prometheus.yml >> ./logs/out.log 2>&1 &

重新加载配置/更新配置shell:

#!/bin/sh
curl -XPOST http://localhost:9996/-/reload
