*** 202011 创建bot的例子
#2020 evan lai, [29.10.20 16:50] /start BotFather, [29.10.20 16:50] 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 Bot Settings /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 /mygames - edit your games (https://core.telegram.org/bots/games) [beta] /newgame - create a new game (https://core.telegram.org/bots/games) /listgames - get a list of your games /editgame - edit a game /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.

Done! Congratulations on your new bot. You will find it at t.me/lxtx_prom_alert_bot. You can now add a description, about section and profile picture for your bot, see /help for a list of commands.

Use this token to access the HTTP API:
1157710367:AAFD9YLsjdQ_t7botbVLa4xxWrOc9LVHNYc
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"}]}}]}
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'

* 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

for: 1m
labels:
severity: page
annotations:
summary: "Instance {{ $labels.instance }} MEM usgae high"
description: "{{ $labels.instance }} MEM usage above 85% (current value: {{ $value }})"
