均采用docker-compose部署Prometheus基础环境

部署参考https://blog.csdn.net/ht9999i/article/details/134733793?spm=1001.2014.3001.5501 开头

一.部署Prometheus

# cat docker-compose.yml 
version: "3"
services:prometheus:#image: prom/prometheus:v2.0.0image: prom/prometheus:v2.18.1container_name: prometheuscommand: --config.file=/etc/prometheus/prometheus.yml --storage.tsdb.path=/prometheus --storage.tsdb.retention=30duser: 0:0ports:- 9090:9090volumes:- /data/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml- /data/prometheus/alerts/:/etc/prometheus/rules.d/- /data/prometheus/data/:/prometheus- /etc/localtime:/etc/localtime:ro

准备数据目录

# cat /data/prometheus/prometheus.ymlglobal:scrape_interval:     120s # Set the scrape interval to every 15 seconds. Default is every 1 minute.evaluation_interval: 120s # Evaluate rules every 15 seconds. The default is every 1 minute.scrape_timeout: 50s# scrape_timeout is set to the global default (10s).# Attach these labels to any time series or alerts when communicating with# external systems (federation, remote storage, Alertmanager).external_labels:monitor: 'tencent-prom-stack'# Alertmanager configuration

告警规则文件

# cat /data/prometheus/alerts/node-rule.yml ###按照格式追加  ,instance!="10.x.xx.xx:9100" 即可，添加白名单
groups:
- name: noderules:# Alert for any instance that is unreachable for >5 minutes.- alert: NodeDownexpr: up * on(instance) group_left(nodename) (node_uname_info) == 0for: 5mlabels:serverity: deadlyannotations:summary: "Instance {{ $labels.instance }} down"description: "{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 5 minutes."- alert: InstanceDownexpr: up == 0for: 5mlabels:serverity: deadlyannotations:summary: "Instance {{ $labels.instance }} down"description: "{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 5 minutes."

启动

docker-compose up -d

二. 部署snmp_exporter

项目地址：https://github.com/prometheus/snmp_exporter/releases

下载项目文件

https://github.com/prometheus/snmp_exporter/releases

docker 部署

docker run -d --name snmp-exporter  --restart=always -m 1g \--volume /data/snmp_exporter/conf:/config \--network host prom/snmp-exporter:v0.20.0 \--web.listen-address :9116 \--config.file=/config/snmp.yml

二进制部署

# cat /etc/systemd/system/snmp_exporter.service 
[Unit]
Description=node_exporter
After=network.target[Service]
ExecStart=/data/snmp_exporter/snmp_exporter --config.file=/data/snmp_exporter/snmp.yml
Restart=on-failure[Install]
WantedBy=multi-user.target

三. 网络设备型号确定 snmp oid 表查询

上面的snmp.yml 需要自己适配设备品牌和oid号 才能采集到数据
