webhook is not working

[surendra matta]

Hi Team,

i am sending  multiple alerts one is email alert and another is to msteam channel using webhook.

My configuration in alertmanger .yml

route:
  group_by: ['alertname']
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 1h
  receiver: 'ms_teams'
  routes:
      - receiver: "ms_teams"
        group_wait: 10s
        match_re:
          severity: critical|warning
        continue: true

      - receiver: "send_email"
        group_wait: 10s
        match_re:
          severity: critical
        continue: true

receivers:
  - name: "ms_teams"
    webhook_configs:
      - url: 'https://<mycmp>/webhookb2/094e8920-b8d3-49ee-a7d4-8576b636ecbb@44b79a67-d972-49ba-9167-8eb05f754a1a/IncomingWebhook/76c301af46724afcb5d27366adc7e31e/71493bd4-0176-499c-bc34-1064b9e3e72e'
        send_resolved: true
           
  - name: "send_email"
    email_configs:
      - to: <my cmp email id>
        from : <sample email id>
        smarthost: <my smtp config>
        require_tls: false
        send_resolved: true

if  i test the email individual i am getting email alert but when i include with the   webhook is not working and i am getting 400 status code for webhook and it is impacting the email alert too.

 FYI.. i tested this webhook from Grafana notification channel, it's working and able to get the alerts to  msteams.

Please check the above config and let me know if i miss any thing.

Regards,

Venkat

> i am getting 400 status code for webhook

That means you are invoking the webhook wrongly - 400 means bad request sent by client. The body of the 400 message probably tells you what you're doing wrong.

The JSON body that Alertmanager POSTs is fixed, and defined here:

https://prometheus.io/docs/alerting/latest/configuration/#webhook_config

I am guessing that the webhook receiver that you're sending to needs its data in a different format.

If you google for "alertmanager teams" then the first hit is this:

https://medium.com/javarevisited/react-faster-alertmanager-to-teams-fa888bcd7c01

They are using a third-party package called "prom2teams"  to convert an alertmanager webhook into a form that Teams will accept.

i tried to install the prom2teams in windows 2016 , it's throwing below error

did we have any other alternative, if yes- could you please provide me an example because it's really important to our POC.

[Brian Candler]

os.uname() definitely exists in Linux, but you appear to be trying to run it under Windows.

If you need this urgently for your POC, then the easiest approach will be to run prom2teams under Linux, or under docker.  See http://www.catb.org/~esr/faqs/smart-questions.html#idm585

Maybe you can find a local Python programmer who can modify it to work under Windows.  Then you can submit your enhancement to the prom2teams project.  

If none of those suggestions are any good to you, then please use Google to find other examples of people who have interfaced Alertmanager to Teams, and how they did it.

 - name: "ms_teams"
    webhook_configs:
       - url: <mywebnook>
        basic_auth:
          username: <userid>
          password: <pwd>
      send_resolved: true 

can I pass user and pwd like this? Please correct me if I am wrong.

[surendra matta]

it's working I tweaked the http_config

- url: '<webhook>'
      send_resolved: true
      http_config:
        basic_auth:
          username: <username>
          password:  <pwd>
