Prometheus+Grafana多方位监控

契机

基础

docker安装

#grafana安装+挂载data
mkdir /x/grafana-storage
chmod 777  /x/grafana-storage
docker run -d \
-p 3000:3000 \
--name=grafana \
-v /x/grafana-storage:/var/lib/grafana \
grafana/grafana#promethes安装+挂载yml
mkdir /x/prometheus
#配置文件在下面
vim /x/prometheus/prometheus.yml
docker run  -d \
-p 9090:9090 \
--privileged=true \
--restart always \
--name=prometheus \
-v /x/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml  \
prom/prometheus#进入grafana
http://localhost:3000
默认密码：admin admin
#修改ui和语言
#导入数据源prometheus

prometheus.yml最终配置

ECS监控

安装

如果选用的火山云的服务器直接参考，如果不是火山云需要参考文档安装

https://www.volcengine.com/docs/6731/1195154
https://www.volcengine.com/docs/6408/69457

#查看监控状态
systemctl status cloud-monitor-agent
#查看9091端口监听
ss -naltp | grep 9091
#返回如下信息时，表示监控组件工作正常，9091 端口已开启。
LISTEN     0      128       [::]:9091                  [::]:*                   users:(("cloud-monitor-a",pid=1661,fd=3))
#老火山服务器升级组件
sed -i 's/Prometheus: false/Prometheus: true/' /usr/local/cloud-monitor-agent/config.yaml && systemctl restart cloud-monitor-agent
#查看端口是否正常访问
curl 127.0.0.1:9091/metrics

监控配置

#抓取配置
scrape_configs:#ECS监控- job_name: nodestatic_configs:- targets: [ 'localhost:9091','localhost1:9091','localhost2:9091']

Nginx监控

安装

#查看nginx是否安装stub模块
nginx -V 2>&1 | grep -o with-http_stub_status_module#没安装的话需要参考其他教程安装#修改nginx.conf
server {listen 9088; listen [::]:9088; server_name localhost; location = /stub_status { stub_status;}
}#nginx配置刷新
nginx -t
nginx -s reload#校验
curl http://localhost:9088/stub_status#安装exporter
mkdir -p /home/prometheus_exporter/{nginx,es}
cd /home/prometheus_exporter/nginx
#这里要根据系统版本选择
wget https://github.com/nginxinc/nginx-prometheus-exporter/releases/download/v1.1.0/nginx-prometheus-exporter_1.1.0_linux_amd64.tar.gz
tar -xvf nginx-prometheus-exporter_1.1.0_linux_amd64.tar.gz
nohup /home/prometheus_exporter/nginx/nginx-prometheus-exporter -nginx.scrape-uri=http://localhost:9088/stub_status >> /dev/null 2>&1 &

监控配置

#抓取配置
