Promethous+Alertmanager+Grafana
监控技术栈如下:
Prometheus(最新版):基于TSDB的微服务指标采集&报警;
Alertmanager:报警服务;
Grafana(>=5.x):监控报表展示。
一、软件部署
1.1 Prometheus安装
# wget https://github.com/prometheus/prometheus/releases/download/v2.5.0/prometheus-2.5.0.linux-amd64.tar.gz
# tar zxvf prometheus-2.5.0.linux-amd64.tar.gz -C /usr/local/
# cd /usr/local/
# ln -s prometheus-2.5.0.linux-amd64 prometheus
# chown work:work prometheus* -R
# cd prometheus
# ls
# console_libraries consoles LICENSE NOTICE prometheus prometheus.yml promtool
1.2 Alertmanager安装
# wget https://github.com/prometheus/alertmanager/releases/download/v0.15.3/alertmanager-0.15.3.linux-amd64.tar.gz
# tar zxvf alertmanager-0.15.3.linux-amd64.tar.gz
# ln -s alertmanager-0.15.3.linux-amd64 alertmanager
# chown work:work alertmanager* -R
# cd alertmanager
# ls
# alertmanager alertmanager.yml amtool LICENSE NOTICE
1.3 Grafana安装
# wget wget https://dl.grafana.com/oss/release/grafana-5.3.4-1.x86_64.rpm
# rpm -Uvh grafana-5.3.4-1.x86_64.rpm
# systemctl restart grafana.service
二、服务配置
2.1 Prometheus配置
指定服务监听alertmanager端口及报警规则目录
vim /usr/local/prometheus/prometheus.yml
#配置alertmanager信息
alerting:
alertmanagers:
- static_configs:
- targets: ['localhost:9093']
#配置告警规则目录
rule_files:
- /usr/local/prometheus/rules/*.rules
2.2 Rules策略配置
创建一个服务down的报警规则
vim /usr/local/prometheus/rules/service_down.rules
groups:
- name: ServiceStatus #规则组名称
rules:
- alert: ServiceStatusAlert #单个规则的名称
expr: up == 0 #匹配规则, up==0
for: 10s #持续时间
labels: #标签
project: APP #自定义lables
annotations: #告警正文
summary: "Instance {{ $labels.instance }} down"
description: "{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 1 minutes."
2.3 Alertmanager配置
vim /usr/local/alertmanager/alertmanager.yml
#全局配置,比如配置发件人
global:
resolve_timeout: 5m #处理超时时间,默认为5min
smtp_smarthost: 'smtp.163.com:25' # 邮箱smtp服务器代理
smtp_from: 'zabbix@minminmsn.com' # 发送邮箱名称
smtp_auth_username: 'zabbix@minminmsn.com' # 邮箱名称
smtp_auth_password: '12345678xxOO' # 邮箱密码或授权码
# 定义模板信息,可以自定义html模板,发邮件的时候用自己定义的模板内容发
templates:
- 'template/*.tmpl'
# 定义路由树信息,这个路由可以接收到所有的告警,还可以继续配置路由,比如project: APP(prometheus 告警规则中自定义的lable)发给谁
route:
group_by: ['alertname'] # 报警分组依据
group_wait: 10s # 最初即第一次等待多久时间发送一组警报的通知
group_interval: 60s # 在发送新警报前的等待时间
repeat_interval: 1h # 发送重复警报的周期 对于email配置中,此项不可以设置过低,否则将会由于邮件发送太多频繁,被smtp服务器拒绝
receiver: 'email' # 发送警报的接收者的名称,以下receivers name的名称
# 定义警报接收者信息
receivers:
- name: 'email' # 路由中对应的receiver名称
email_configs: # 邮箱配置
- to: 'admin@minminmsn.com' # 接收警报的email配置
#html: '{{ template "test.html" . }}' # 设定邮箱的内容模板
三、服务启动
3.1 Prometheus启动
/usr/local/prometheus/prometheus --config.file=prometheus.yml --web.enable-lifecycle --web.external-url=http://127.0.0.1:9090 --storage.tsdb.path=/data1/prometheus/data &
3.2 Alertmanager启动
/usr/local/alermanager/alertmanager &
四、报警验证
4.1 Prometheus
4.2 Rules
4.3 Alerts
4.4 Mails
