一、普罗米修斯（Prometheus）是什么？

prometheus是由谷歌研发的一款开源的监控软件，它通过安装在远程机器上的exporter，通过HTTP协议从远程的机器收集数据并存储在本地的时序数据库上。目前已经被云计算本地基金会托管，是继k8s托管的第二个项目，号称是下一代监控。

1.下载Prometheus工具（切记和操作系统版本对应）

下载地址：https://prometheus.io/download/

操作系统	版本
x86	prometheus-2.45.0.linux-amd64.tar.gz
linux	prometheus-2.45.0.linux-amd64.tar.gz
window	prometheus-2.45.0.windows-amd64.zip

2.解压命令

tar -zxvf prometheus-2.45.0.linux-amd64.tar.gz

3.修改prometheus.yml配置

# my global config
global:scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.# scrape_timeout is set to the global default (10s).# Alertmanager configuration 告警信息服务配置，用来发送告警信息，敲黑板：很重要
alerting:alertmanagers:- static_configs:- targets:- 192.168.10.111:9093# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
# 自定义规则，会获取指定目录下的所有规则配置文件
rule_files:- "rules/*.yml"# - "second_rules.yml"# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.- job_name: "prometheus"# metrics_path defaults to '/metrics'# scheme defaults to 'http'.static_configs:- targets: ["localhost:9090"]- job_name: 'gateway'static_configs:- targets: ['192.168.10.111:11200']- job_name: 'eureka'static_configs:- targets: ['192.168.10.111:11300']- job_name: 'object'scrape_interval: 15sscrape_timeout: 10smetrics_path: '/object-library-api-service/actuator/prometheus'static_configs:- targets: ['192.168.10.111:11198']- job_name: 'sync'static_configs:- targets: ['192.168.10.111:11025']
# 监听服务信息，定义服务名称，暴露接口给普罗米修斯进行验证，配置指定的gargets信息- job_name: 'user'metrics_path: '/actuator/prometheus'static_configs:- targets: ['192.168.11.2:7777']
#  - job_name: 'alertmanager'
#    static_configs:
#      - targets: ['192.168.10.111:9093']

4.免密版（默认端口9090）

[Unit]
Description=prometheus[Service]
Restart=on-failure
ExecStart=/longjin/prometheus/prometheus --config.file=/longjin/prometheus/prometheus.yml

4.加密版（默认端口9090）

[Unit]
Description=prometheus[Service]
Restart=on-failure

二、告警（Alertmanager）是什么？

Alertmanager 主要用于接收 Prometheus 发送的告警信息，它支持丰富的告警通知渠道，而且很容易做到告警信息进行去重，降噪，分组等，是一款前卫的告警通知系统。

1.下载地址

下载地址：https://prometheus.io/download/

2.解压命令

tar -zxvf alertmanager-0.26.0.linux-amd64.tar.gz

3.修改配置文件

route:group_by: ['alertname']group_wait: 30sgroup_interval: 5mrepeat_interval: 1hreceiver: 'dingding.alertname'
receivers:
# 配置调用钉钉服务接口，用来推送消息- name: 'dingding.alertname'webhook_configs:- url: 'http://192.168.10.111:8060/dingtalk/alertname/send'send_resolved: true
inhibit_rules:- source_match:severity: 'critical'target_match:severity: 'warning'equal: ['alertname', 'dev', 'instance']

4.配置Alertmanager启动文件（默认端口9093）

[Unit]
Description=alertmanager[Service]
Restart=on-failure
ExecStart=/longjin/prometheus/alert/alertmanager --config.file=/longjin/prometheus/alert/alertmanager.yml --storage.path=/longjin/prometheus/alert/data/

三、钉钉（dingtalk）是什么？

钉钉(DingTalk)是阿里巴巴集团专为中国企业打造的免费沟通和协同的多端平台,提供PC版,Web版,Mac版和手机版,支持手机和电脑间文件互传。

1.下载地址：

下载地址：https://github.com/timonwong/prometheus-webhook-dingtalk/releases

2.解压命令

tar -zxvf prometheus-webhook-dingtalk-2.1.0.linux-amd64.tar.gz

3.修改配置文件

cp一份配置文件出来，切记改成你们自己钉钉机器人的配置。查看钉钉机器人基本信息就可以了

4.启动钉钉服务（默认端口8060）

[Unit]
Description=dingtalk[Service]
Restart=on-failure
WorkingDirectory=/longjin/prometheus/dingtalk

总结

人生物语：自己不努力上进，何来的得心应手？不是娇靥，就可以有馥郁的芳香；不是有刀戟就可以百战百胜。你不是急流，不能湍飞；你不是花儿，你没有自带的芳香；你不是海洋，不可海纳百川。
