# If set, the ntfy message will contain a "Silence" button, which can be used
# to create a silence via the Alertmanager API. Because of limitations in ntfy,
# the request will be proxied through ntfy-alertmanager. Therefore ntfy-alertmanager
# needs to be exposed to external network requests and base-url has to be set.

# When alert-mode is set to "single" all alert labels will be used to create the silence.
# When it is "multi" common labels between all the alerts will be used. WARNING: This
