安装Prometheus开始 Prometheusnode_exporter Agent组件
一、部署Prometheus
1、启动容器将文件拷贝出来
docker run -d prom/prometheus2、容器将文件拷贝出来 docker cp 容器ID:/usr/share/prometheus/console_libraries /usr/share/prometheus/docker cp 容器ID:/usr/share/prometheus/consoles/ /usr/share/prometheus/docker cp 容器ID:/etc/prometheus /data/docker_data/Promthues/confdocker cp 容器ID:/prometheus /data/docker_data/Promthues/data3、修改数据存储权限。 默认容器中是nobodynobody 只能修改为777
chmod 777 /data/docker_data/Promthues/data4、启动docker
docker run --name prometheus -d \
-v /data/docker_data/Promthues/data:/prometheus \
-v /data/docker_data/Promthues/conf:/etc/prometheus \
-p 9090:9090 prom/prometheus \
--config.file/etc/prometheus/prometheus.yml \
--web.listen-address0.0.0.0:9090 \
--storage.tsdb.path/prometheus \
--web.console.libraries/usr/share/prometheus/console_libraries \
--web.console.templates/usr/share/prometheus/consoles \
--storage.tsdb.retention30d \
--web.enable-lifecycle二、访问WEB控制台
访问URL IP9090三、安装node_exporter 组件
docker run -d --name node_exporter \--restartalways \--nethost \--pidhost \-v /proc:/host/proc:ro \-v /sys:/host/sys:ro \-v /:/rootfs:ro \prom/node-exporter \--path.procfs/host/proc \--path.rootfs/rootfs \--path.sysfs/host/sys \--collector.textfile.directory/data/docker_data/Promthues/prom \--collector.filesystem.ignored-mount-points^/(sys|proc|dev|host|etc)($$|/)四、配置 Prometheus 以监视自身
global: #全局scrape_interval: 15s # 默认情况下即拉取业务监控数据的间隔时间,默认一分钟scrape_timeout: 10s # 即拉取业务监控数据接口的超时时间evaluation_interval: 15s # 默认评估规则的频率,默认一分钟# Attach these labels to any time series or alerts when communicating with# external systems (federation, remote storage, Alertmanager).external_labels:monitor: codelab-monitorscrape_configs:# The job name is added as a label jobjob_name to any timeseries scraped from this config.- job_name: prometheus# Override the global default and scrape targets from this job every 5 seconds.scrape_interval: 5sstatic_configs:- targets: [localhost:9090]labels:name: Prometheus五、控制台抓取数据
1、重新查看当前Prometheus的标签 2、重新查看当前Prometheus的标签
avg by (job, instance, mode) (rate(node_cpu_seconds_total{instance10.1.32.231}[5m]))3、修改Prometheus 主配置文件
mkdir -p /data/docker_data/Promthues/conf/rulesglobal: #全局scrape_interval: 15s # 默认情况下即拉取业务监控数据的间隔时间,默认一分钟scrape_timeout: 10s # 即拉取业务监控数据接口的超时时间evaluation_interval: 15s # 默认评估规则的频率,默认一分钟# Attach these labels to any time series or alerts when communicating with# external systems (federation, remote storage, Alertmanager).external_labels:monitor: codelab-monitorrule_files:- rules/*.yml # 指定自定义规则文件存放目录scrape_configs:# The job name is added as a label jobjob_name to any timeseries scraped from this config.- job_name: prometheus# Override the global default and scrape targets from this job every 5 seconds.scrape_interval: 5sstatic_configs:- targets: [localhost:9090]labels:name: Prometheus4、配置Prometheus记录规则
vim /data/docker_data/Promthues/conf/rules/cpu-node.ymlgroups:
- name: cpu-noderules:- record: job_instance_mode:node_cpu_seconds:avg_rate5mexpr: avg by (job, instance, mode) (rate(node_cpu_seconds_total{instance10.1.32.231}[5m]))5、热加载Prometheus 服务
检查语法是否符合
docker exec -it prometheus promtool check config /etc/prometheus/prometheus.ym热加载配置文件
curl -XPOST http://localhost:9090/-/reload6、重新登录Web控制台 点击匹配规则自动跳转到Web 查询界面
匹配规则作为告警阈值进行钉钉通知告警 后面篇章会记录学习笔记。
