and this is my current configuration:
config:
global:
resolve_timeout: 5m
inhibit_rules: []
route:
group_by: ['namespace']
group_wait: 30s
group_interval: 5m
repeat_interval: 12h
receiver: 'MS-TEAMS' #original value is 'null'
routes: []
receivers:
- name: 'null'
- name: 'MS-TEAMS'
msteams_config:
- send_resolved: true
webhook_url: "webhook_url"
title: "{{ template \"msteams.default.title\" . }}" # Default title template
summary: "{{ .CommonAnnotations.summary | default \"No summary available\" }}" # Ensures a default value
text: "{{ .CommonAnnotations.description | default .CommonAnnotations.summary }}" # Fallback to summary if description is missing
max_alerts: 1 # Optional, sends alerts individually, remove later
templates:
- '/etc/alertmanager/config/*.tmpl'following this documentation on alertmanager-msteams-config:
https://prometheus.io/docs/alerting/latest/configuration/#msteams_config
tried to do a curl to test:
curl -XPOST -H "Content-Type: application/json" -d '[ { "labels": { "alertname": "TestAlert", "severity": "critical" }, "annotations": { "summary": "Manual test alert for Microsoft Teams", "description": "If you see this message in Teams, the webhook is working!" } } ]' http://localhost:9093/api/v2/alerts
which gives an empty response and i see the alert in alertmanager but not in teams, so i tested the webhook to check if it is working:
curl -XPOST -H "Content-Type: application/json" -d '{ "title": "Teams Webhook Test", "text": "If you see this in Teams, the webhook is working!" }'webhook-url
with this i can see the message in the teams channel.
appreciate all the help and support
