搭建基于Prometheus+Grafana监控平台

• 本文从实战出发,不讲作用只讲部署
• • 监控机器状态(端口9100)

本文从实战出发,不讲作用只讲部署

Grafana下载
建议手动使用安装rpm。

sudo yum install initscripts fontconfig
yum install urw-fonts
yum install freetype
rpm -Uvh grafana<!-- version -->


sudo service grafana-server start #开启服务

systemctl daemon-reload #重新加载
systemctl start grafana-server #开启
systemctl status grafana-server #状态

Prometheus下载
1、下载二进制包

prometheus-2.6.1.linux-amd64.tar.gz
解压包：
tar xvzf prometheus-2.6.1.linux-amd64.tar.gz 
备份配置文件：
mv prometheus.yml prometheus.yml-bak
启动命令：
sudo  ./prometheus --config.file=prometheus.yml
nohup ./prometheus --config.file=prometheus.yml &

5、修改配置文件9090监控本机：

#vim prometheus.yml
# 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'
    static_configs:
    - targets: ['localhost:9090']

  - job_name: 'Linux'
    static_configs:
    - targets: ['10.19.85.4:9100']
      labels:
          instance: '10.19.85.4'
    - targets: ['10.19.85.6:9100']
      labels:
          instance: '10.19.85.6'
    - targets: ['10.19.85.9:9100']
      labels:
          instance: '10.19.85.9'

  - job_name: 'pgsqldb'
    static_configs:
    - targets: ['10.19.85.10:9187']
      labels:
          instance: 'pg10'
  - job_name: 'cockroachdb'
    metrics_path: '/_status/vars'
    #Insecure mode:
    #scheme: 'http'
    #Secure mode:
    scheme: 'https'
    tls_config:
      insecure_skip_verify: true
    static_configs:
    - targets: ['10.19.85.6:7071']
      labels:
        cluster: 'my-cockroachdb-cluster6'
    - targets: ['10.19.85.9:7071']
      labels:
        cluster: 'my-cockroachdb-cluster9'
    - targets: ['10.19.85.10:7071']
      labels:
        cluster: 'my-cockroachdb-cluster10'
  - job_name: 'rocketmq'
    static_configs:
    - targets: ['10.19.85.4:5557']

  - job_name: 'redis'
    static_configs:
    - targets: ['10.19.85.4:9121']
      labels:
           instance: 'reds1'

Prometheus官网下载node_exporter

解压命令
tar -zxvf node_exporter-0.18.1.linux-amd64.tar.gz -C /data/prometheus/prometheus-2.17.1.linux-amd64/exporter
启动启动
nohup ./node_exporter &
