一、各软件功能简介
prometheus:Prometheus(是由go语言(golang)开发)是一套开源的监控&报警&时间序列数 据库的组合。主要优点:外部依赖安装使用超简单、系统集成 多等
grafana:Grafana 是一款采用 go 语言编写的开源应用,主要用于大规模指标数据的 可视化展现,是网络架构和应用分析中最流行的时序数据展示工具,目前已经支 持绝大部分常用的时序数据库。主要优点:展示方便、数据源种类多、内置通知提醒功能
altermanager:AlterManager是一个基于开源框架Prometheus和Grafana的告警管理系统。它可以帮助我们轻松地实现监控告警功能,并支持多种告警方式。主要优点:告警方式多样
prometheus-webhook-dingtalk:prometheus-webhook-dingtalk 是一个用于将 Prometheus 告警通知发送到钉钉群组的 webhook 模块。它提供了一种与钉钉无缝集成的方式,使监控团队能够及时接收和处理告警通知,并进行有效的团队协作。
二、基础准备工作
docker安装:这个太简单了我就不介绍了,后期有时间再出一篇专门安装docker的
服务器:由于我是测试就是用了一台机器centos7 ip:10.10.30.34(后期中配置文件需要用到)
安装目录:创建目录mkdir -p /data/prometheus
切换目录cd /data/prometheus/
,主要用于各种软件的配置和数据文件存放
三、prometheus准备工作
3.1、prometheus配置文件和数据文件
数据文件准备:创建目录mkdir -p prometheus/data
修改权限chmod 777 prometheus/data
实际应用可以根据具体使用情况设置权限
配置文件准备:vim prometheus/prometheus.yml
global:
scrape_interval: 15s # 多久收集一次数据
evaluation_interval: 15s # 多久评估一次规则
scrape_timeout: 10s # 每次收集数据的超时时间
scrape_configs: #收集数据配置列表
- job_name: prometheus # 必须配置, 自动附加的job labels, 必须唯一
static_configs:
- targets: ['10.10.30.34:9090'] # 指定prometheusip端口
labels:
instance: prometheus #标签
- job_name: ehospital-exploit-database #监控客户端
static_configs:
- targets: ['10.10.30.34:9100']
labels:
instance: eehospital-exploit-database
alerting: #Alertmanager相关的配置
alertmanagers:
- static_configs:
- targets:
- 10.10.30.34:9093 #指定告警模块
rule_files: #告警规则文件, 可以使用通配符
- "/etc/prometheus/rules/*.yml"
3.2、prometheus告警配置
创建目录:mkdir rules
用于存放告警和触发文件
通用规则:vim rules/alert-rules.yml

四、grafana配置
创建目录:mkdir -p grafana/grafana-storage
修改权限:chmod 777 grafana/grafana-storage
grafana.ini准备:先启动一个grafana容器docker run -d --name=grafana -p 3000:3000 grafana/grafana
,然后拷贝文件docker cp 93ac9e93e97a:/etc/grafana/grafana.ini ./grafana/
五、alertmanager配置
创建文件:mkdir alert
配置文件:vim alert/alertmanager.yml
route:
group_by: ['dingding'] #根据告警规则名进行分组
group_wait: 30s #在组内等待配置时间,如组内30s出现同一报警,在一个组内出现
group_interval: 1h #告警频率,一条告警消息发送后,等待1h发送第二组报警
repeat_interval: 1h #报警间隔时间,如果1h内未修复,重新发送告警
receiver: 'dingding.webhook1'
routes:
- receiver: 'dingding.webhook1'
match_re:
alertname: ".*"
receivers:
- name: 'dingding.webhook1' #可设置多个接收方
webhook_configs:
- url: 'http://10.10.30.34:8060/dingtalk/webhook1/send'
send_resolved: true #恢复后收到告警
inhibit_rules:
- source_match: #配置了仰制告警
severity: 'critical'
target_match:
severity: 'warning'
equal: ['alertname', 'dev', 'instance']
六、webhook配置
创建目录:mkdir webhook

#no_builtin_template: true
## Customizable templates path
templates:
# - contrib/templates/legacy/template.tmpl
- /etc/prometheus-webhook-dingtalk/templates/default.tmpl
## You can also override default template using `default_message`
## The following example to use the 'legacy' template from v0.3.0
#default_message:
# title: '{{ template "legacy.title" . }}'
# text: '{{ template "legacy.content" . }}'
## Targets, previously was known as "profiles"
targets:
webhook1:
url: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxx #钉钉机器人路径
# secret for signature
secret: SEC74939daa62xxx.xxxxxx #钉钉机器人加密标签
webhook2:
url: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxxxxx
webhook_legacy:
url: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxxxxx
# Customize template content
message:
# Use legacy template
title: '{{ template "legacy.title" . }}'
text: '{{ template "legacy.content" . }}'
webhook_mention_all:
url: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxxxxx
mention:
all: true
webhook_mention_users:
url: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxxxxx
mention:
mobiles: ['156xxxx8827', '189xxxx8325']
prometheus-webhook-dingtalk模板
创建目录:mkdir webhook/template
模板创建:vim webhook/template/default.tmpl
{{ define "__subject" }}
[{{ .Status | toUpper }}{{ if eq .Status "firing" }}:{{ .Alerts.Firing | len }}{{ end }}]
{{ end }}
{{ define "__alert_list" }}{{ range . }}

{{ define "ding.link.content" }}{{ template "default.content" . }}{{ end }}
{{ template "default.title" . }}
{{ template "default.content" . }}
七、docker实例创建
创建yml文件:vim docker-compose.yml
version: '3.2'
services:
prometheus:
image: prom/prometheus
restart: "always"
ports:
- 9090:9090
container_name: "prometheus"
volumes:
- "./prometheus/prometheus.yml:/etc/prometheus/prometheus.yml"
- "./rules:/etc/prometheus/rules"
- "./prometheus/data:/prometheus"
command:
- '--config.file=/etc/prometheus/prometheus.yml' # 设置yml路径 跟上面挂载对应
- '--storage.tsdb.path=/prometheus' #设置数据路径 跟上面挂载对应
alertmanager:
image: prom/alertmanager:latest
restart: "always"
ports:
- 9093:9093
container_name: "alertmanager"
volumes:
- "./alert/alertmanager.yml:/etc/alertmanager/alertmanager.yml"
command:
- '--config.file=/etc/alertmanager/alertmanager.yml' # 设置yml路径 跟上面挂载对应
webhook:
image: timonwong/prometheus-webhook-dingtalk
restart: "always"
ports:
- 8060:8060
container_name: "webhook" #token指定钉钉
volumes:
- "./webhook/config.yml:/etc/prometheus-webhook-dingtalk/config.yml"
- "./webhook/template/default.tmpl:/etc/prometheus-webhook-dingtalk/templates/default.tmpl"
command:
- '--config.file=/etc/prometheus-webhook-dingtalk/config.yml' # 设置yml路径 跟上面挂载对应
grafana:
image: grafana/grafana
restart: "always"
ports:
- 3000:3000
container_name: "grafana"
volumes:
- "./grafana/grafana.ini:/etc/grafana/grafana.ini" #配置文件自行拷贝出来
- "./grafana/grafana-storage:/var/lib/grafana"
创建docker:docker-compose -f docker-compose.yml up -d
八、钉钉添加机器人
自己创建一个群呗,至少两个人才能建群呀!然后按下面图片操作就行了,反正点点就行就不细说了
后面就是啥名字、链接、加签啥的我懒得打马了就不截图了,还不会的就呵呵了
九、验证
安都安装好了那不得验证一下啊!稍微懂点的人应该已经知道了,我配置了监控服务器的指标,但是我没有启动node-export,那肯定会报警呀!没错报警信息如下啊!
安装node-exporter:vim node-exporter-compose.yml
version: '3.2'
services:
node-exporter:
image: prom/node-exporter
restart: "always"
ports:
- 9100:9100
container_name: "node-exporter"
volumes:
- "/proc:/host/proc:ro"
- "/sys:/host/sys:ro"
- "/:/rootfs:ro"
启动node-exporter:docker-compose -f node-exporter-compose.yml up -d
这不启动了节点吗?那肯定有修复告警呀!没错,收到了,只是我设置了1h后才再告警收到的慢了点啊!大家可以根据需求自己设置时间啊!
ps:水平高的大神自己看官方文档去整啊!小弟这给大家参考参考就行了啊!加油!!!
