Hi all.
We were recently testing grouping via the special value '...' for a
specific Slack receiver.
Looking at the documentation this seems feasible and correct. However,
after introducing the grouping, no alert belonging to the receiver was
delivered to Slack any more.
The routing configuration looks like the following:
route:
receiver: 'none'
group_by: [severity, stack, environment]
group_wait: 30s
group_interval: 5m
repeat_interval: 6h
routes:
- receiver: 'slack_firmware_rc'
match_re:
stack: xxx
instance: yyy
#
# other "stack"-based receivers here
#
- receiver: 'slack_it'
group_by: ['...'] # disables grouping
match_re:
stack: it
#
# other "stack"-based receivers here
#
I've omitted the other receivers: they weren't touched and seem to continue
working fine. The only receiver that is not working is the "slack_it" one.
Notably we reworked also the templates for the receiver but there is *no* error
in the log at all, meaning the new templates are correctly loaded. Anyway,
just for completion here are the changed parts:
- name: slack_it
slack_configs:
- api_url: 'xxx'
icon_url: 'yyy'
username: 'zzz'
channel: '#out_channel'
send_resolved: true
color: '{{ template "yakkity-color" . }}'
title: '{{ template "yakkity-simple-title" . }}'
text: '{{ template "yakkity-simple-text" . }}'
thumb_url: '{{ template "yakkity-thumb" . }}'
{{ define "yakkity-simple-title" -}}
{{- with index .Alerts 0 -}}
{{- .Annotations.summary -}}
{{- end -}}
{{- end }}
{{ define "yakkity-simple-text" }}
{{- with index .Alerts 0 -}}
{{- .Annotations.description -}}
{{- end }}
:bar_chart: *<{{ .GeneratorURL }}|Graph>*
{{- if .Annotations.runbook }} :notebook: *<{{ .Annotations.runbook }}|
Runbook>* {{- end }}
{{ $filteredLabels :=
"stack|environment|service|job|monitor|severity|hostname" }}
{{ range .Labels.SortedPairs }}{{if not (match $filteredLabels .Name)}}`{{
.Name }}={{ .Value }}` {{ end }}{{ end }}
{{ end }}
Any idea what can be wrong with this new setup?
Thanks in advance,
F.
