I can help you create and manage Telegram bots. If you're new to the Bot API, please see the manual (https://core.telegram.org/bots).

You can control me by sending these commands:

/newbot - create a new bot
/mybots - edit your bots [beta]

Edit Bots
/setname - change a bot's name
/setdescription - change bot description
/setabouttext - change bot about info
/setuserpic - change bot profile photo
/setcommands - change the list of commands
/deletebot - delete a bot

/token - generate authorization token
/revoke - revoke bot access token
/setinline - toggle inline mode (https://core.telegram.org/bots/inline)
/setinlinegeo - toggle inline location requests (https://core.telegram.org/bots/inline#location-based-results)
/setinlinefeedback - change inline feedback (https://core.telegram.org/bots/inline#collecting-feedback) settings
/setjoingroups - can your bot be added to groups?
/setprivacy - toggle privacy mode (https://core.telegram.org/bots#privacy-mode) in groups

Games

/deletegame - delete an existing game

BotFather, [29.10.20 16:50]
Alright, a new bot. How are we going to call it? Please choose a name for your bot.

evan lai, [29.10.20 16:50]
/newbot

evan lai, [29.10.20 16:51]
evan_alert_bot

BotFather, [29.10.20 16:51]
Good. Now let's choose a username for your bot. It must end in `bot`. Like this, for example: TetrisBot or tetris_bot.

evan lai, [29.10.20 16:51]
evan_alert_bot

BotFather, [29.10.20 16:51]
Done! Congratulations on your new bot. You will find it at t.me/evan_alert_bot. You can now add a description, about section and profile picture for your bot, see /help for a list of commands. By the way, when you've finished creating your cool bot, ping our Bot Support if you want a better username for it. Just make sure the bot is fully operational before you do this.

Use this token to access the HTTP API:
1363904888:AAGeUIoxxRMlxk9zHUa2MTRi1My9HDBP69w
Keep your token secure and store it safely, it can be used by anyone to control your bot.

For a description of the Bot API, see this page: https://core.telegram.org/bots/api

使用API/bottoken/API方法getMe获取自己的id


curl https://api.telegram.org/bot1157710367:AAFD9YLsjdQ_t7xxxxxLa4imWrOV9LVHNYc/getMe


#前面有bot字母 
sns:~# curl https://api.telegram.org/bot1157710367:AAFD9YLsjdQ_xxxxotbVLa4imWrOV9LVHNYc/getMe
{"ok":true,"result":{"id":1157710367,"is_bot":true,"first_name":"prom_alert_bot","username":"lxtx_prom_alert_bot","can_join_groups":true,"can_read_all_group_messages":false,"supports_inline_queries":false}}

创建组

获取群ID

在Telegram新建group,然后添加成员刚创建的机器人 (prom_alert_bot) ,调用API方法getUPdates获取群ID

 curl https://api.telegram.org/bot1157710367:AAFD9YLsjdQ_t7botbVLa4imWrOV9LVHNYc/getUpdates
{"ok":true,"result":[{"update_id":367831744,
"message":{"message_id":1,"from":{"id":796717144,"is_bot":false,"first_name":"evan","last_name":"lai","username":"linuxsa"},"chat":{"id":-470646458,"title":"alerm","type":"group","all_members_are_administrators":true},"date":1597202656,"new_chat_participant":{"id":1157710367,"is_bot":true,"first_name":"prom_alert_bot","username":"lxtx_prom_alert_bot"},"new_chat_member":{"id":1157710367,"is_bot":true,"first_name":"prom_alert_bot","username":"lxtx_prom_alert_bot"},"new_chat_members":[{"id":1157710367,"is_bot":true,"first_name":"prom_alert_bot","username":"lxtx_prom_alert_bot"}]}}]}

telegram webhook

1.先把 webhook 跑起来


git clone https://github.com/evan886/alertmanager-webhook-telegram-python.git
cd   alertmanager-webhook-telegram-python/docker 
docker build -t alertmanager-webhook-telegram:1.0 .
docker run -d --name telegram-bot \
	-e "bottoken=1157710367:AxxxxxxQ_t7botbVLa4imWrOV9LVHNYc" \
	-e "chatid=4706458" \
	-e "username=evan" \
	-e "password=evanLxx123" \
	-p 9119:9119 alertmanager-webhook-telegram:1.0

配置

cat alertmanager/config.yml

# 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: zhidaoAPP(prometheus 告警规则中自定义的lable)发给谁,project: baoxian的发给谁
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: 'telegram-webhook'       # 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: 'telegram-webhook'
    webhook_configs:
    - url: http://evan:[email protected]:9119/alert

结果查看

正常来说 这时候 你的TG 组就有信息了 ,没的话 就停止一个node export  收不到就有问题喽

trouble

起不来 老报错 level=error ts=2019-08-26T05:52:52.19072198Z caller=main.go:337 msg="Loading configuration file failed" file=/usr/local/prometheus/alertmanager/alertmanager.yml err="yaml: unmarshal errors:\n  line 12: field receivers not found in type config.plain"   解决办法 用了聪的办法  - url: 'http://用户:密码@172.24.103.122:9119/alert'

prometheus alertmanager webhook 配置教程

prometheus+alertmanager+webhook实现自定义监控报警系统

* intro

告警能力在Prometheus的架构中被划分为两个部分,在Prometheus Server中定义告警规则以及产生告警,Alertmanager组件则用于处理这些由Prometheus产生的告警。Alertmanager即Prometheus体系中告警的统一处理中心。 Alertmanager提供了多种内置第三方告警通知方式,同时还提供了对Webhook通知的支持,通过Webhook用户可以完成对告警更多个性化的扩展。

* ins

** using docker or docker-composer

用自带的 compose

https://hub.docker.com/r/prom/alertmanager/dockerfile

      • docker only
 docker pull prom/alertmanager
 docker run --name alertmanager  -d -p 9093:9093   -v /path/to/config.yml:/etc/alertmanager/conf/config.yml prom/alertmanager



* conf

rules


 vim node-up.rules
groups:
- name: node-up
  rules:
  - alert: node-up
    expr: up{job="node-exporter"} == 0
    for: 15s
    labels:
      severity: 1
      team: node
    annotations:
      summary: "{{ $labels.instance }} 已停止运行超过 15s!"

说明一下:该 rules 目的是监测 node 是否存活,expr 为 PromQL 表达式验证特定节点 job="node-exporter" 是否活着,for 表示报警状态为 Pending 后等待 15s 变成 Firing 状态,一旦变成 Firing 状态则将报警发送到 AlertManager,labels 和 annotations 对该 alert 添加更多的标识说明信息,所有添加的标签注解信息,以及 prometheus.yml 中该 job 已添加 label 都会自动添加到邮件内容中,更多关于 rule 详细配置可以参考

#告警解除 

* 自定义告警规则

** CPU load 自定义告警规则

  - alert: high_load-85per
    expr: (100-(avg(irate(node_cpu_seconds_total{mode="idle"}[5m]))by (job)) * 100)  > 80
    #expr: sum(avg without (cpu)(irate(node_cpu{mode!='idle'}[5m]))) by (instance) > 0.81
    #expr: node_load1 > 0.2
    for: 10m
    labels:
      severity: page
    annotations:
      summary: "Instance {{ $labels.instance }} under high load"
      description: "{{ $labels.instance }} of job {{ $labels.job }} is under high load more than  12 minutes."

 FIRING 才会 send email 

** 内存自定义告警规则

#rules file 注意空格在前面哦 
- alert: hostMemUsageAlert
    expr: ((node_memory_MemTotal_bytes -(node_memory_MemFree_bytes+node_memory_Buffers_bytes+node_memory_Cached_bytes) )/node_memory_MemTotal_bytes ) * 100 > 90
    #expr: (node_memory_MemTotal - node_memory_MemAvailable)/node_memory_MemTotal > 0.85
    for: 1m
    labels:
      severity: page
    annotations:
      summary: "Instance {{ $labels.instance }} MEM usgae high"
      description: "{{ $labels.instance }} MEM usage above 85% (current value: {{ $value }})"


成功的自定义报警规则 2020 https://www.shared-code.com/article/84

这个成功的 上面的不成功

((node_memory_MemTotal_bytes -(node_memory_MemFree_bytes+node_memory_Buffers_bytes+node_memory_Cached_bytes) )/node_memory_MemTotal_bytes ) * 100 > 90

常用prometheus告警规则模板(三


自定义Prometheus告警规则

** 磁盘自定义告警

- alert: LowDiskSpaceNodeFilesystemUsage
    expr: 100 - (node_filesystem_free_bytes{mountpoint="/",fstype=~"ext4|xfs"} / node_filesystem_size_bytes{fstype=~"ext4|xfs"} * 100) > 80
    for: 1m
    labels:
      severity: warning
    annotations:
      summary: "Instance {{ $labels.instance  }} :{{ $labels.mountpoint }} 分区使用率过高" 
      description: "{{ $labels.instance  }} : {{ $labels.job  }} :{{ $labels.mountpoint  }} 这个分区使用大于百分之80% (当前值:{{ $value }})"
