Hi Christian,
Based on your advice, I added a “devnull” receiver and set it as default as
below. Does it look correct?
global:
resolve_timeout: 15m
receivers:
- name: devnull
- name: prometheus-snow
webhook_configs:
- url: “https://
http_config:
basic_auth:
username: “xx”
password: “xx”
route:
group_by: ['...']
group_interval: 15m
group_wait: 15m
repeat_interval: 1h
receiver: devnull
routes:
- receiver: "prometheus-snow"
match:
inc: servicenow
