prometheus+node_exporter+grafana实践
介绍:
prometheus:开源监控系统,可参考博客prometheus的搭建与使用
node_exporter:服务器端agent,负责采集服务器基础监控项
grafana:一个开源的度量分析与可视化套件,常用于展示监控信息
安装:
安装node_exporter,启动后监听9100端口
-
wget https://github.com/prometheus/node_exporter/releases/download/v0.16.0-rc.3/node_exporter-0.16.0-rc.3.linux-amd64.tar.gz
-
tar -zxvf node_exporter-0.16.0-rc.3.linux-amd64.tar.gz
-
cd node_exporter-0.16.0-rc.3.linux-amd64
-
./node_exporter
安装grafana,启动后监听3000端口
-
yum install grafana
-
service grafana-server start
配置:
1、配置prometheus,修改prometheus.yml配置文件,增加安装node_exporter的机器,配置完成后重启
-
scrape_configs:
-
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
-
- job_name: 'node_exporter'
-
# metrics_path defaults to '/metrics'
-
# scheme defaults to 'http'.
-
static_configs:
-
- targets: ['localhost:9100']
2、配置grafana增加data source,访问localhost:3000,推荐展示样式选择Node Exporter Full
效果:
