一、安裝：node_exporter
下載地址：https://github.com/prometheus/node_exporter/releases
找到對應的版本進行下載，後解壓並運行
tar -xvf node_exporter-0.17.0.linux-amd64.tar.gz
#進入目錄後運行
sudo ./node_exporter
在瀏覽器中輸入:http://IP:9100 能看到數據即可
二、下載：Prometheus
下載鏈接：https://prometheus.io/download/
下載後解壓編輯配置文件sudo vim prometheus.yml，在scrape_configs欄添加如下配置：
- job_name: "node"
static_configs:
- targets: ["localhost:9100"]
完整版的：
注意：yml文件格式每列要對齊
#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: ['localhost:9090']
- job_name: "node"
static_configs:
- targets: ["localhost:9100"]
在文件夾內啓動：
sudo ./prometheus
啓動後在瀏覽器中訪問：http://IP:9090即可
