1、Prometheus实现钉钉报警
1.1 Prometheus环境
# 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
alerting:
alertmanagers:
- static_configs:
- targets:
- 192.168.204.195:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
- "rule/*.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"]
# 采集JVM监控数据
- job_name: pushgateway
static_configs:
- targets: ['192.168.204.195:9091']
labels:
instance: pushgateway
groups:
- name: node_rule
rules:
- alert: node memory usages
expr: node_memory_usages > 20
for: 10s
labels:
severity: high
annotations:
summary: "【监控告警】{{ $labels.exported_instance }}: 空间使用率异常"
description: "【监控告警】{{ $labels.exported_instance }}: 空间使用率异常,请及时处理。"

1.3 自定义机器人并获取自定义机器人Webhook地址
1、首先创建一个群聊。
进入到钉钉软件的主页面后，点击右上角的加号按钮。
弹出加号里面的选项后，点击上面的发起群聊按钮。
进入到发起群聊界面后选择内部项目群，选择属于个人，点击上面的选择联系人选项。
进入到联系人界面后，选择要加入群聊的好友，最后点击右下角确定即可。
2、选择需要添加机器人的群聊，然后依次单击群设置 > 智能群助手 > 添加机器人。
3、点击添加机器人。
4、选择自定义。
5、点击添加。
6、输入相关信息，点击完成。
加签生成的随机码需要保存，后面会使用到。
7、点击完成。
这样我们就成功添加了自定义钉钉机器人并获取了 Webhook 地址。
获取到的Webhook的地址如下：
