Can we get extra labels into the slack notification?
I am new to this templating language.
Template will help
Thank for the template.
If anybody has issue with "Silence" button on mobile devices (when press Silence on phone nothing happens, button doesn't open Alertmanager silence link), just change quotes (") to (%22) in __alert_silence_link template.
Hope this help.
Awesome thx, why second, third alert has indentation?
It's not an indentation, it's censoring the name of their Prometheus instance
Hi @dewey ! ,
I think there is not about censoring , but actually some indentation appears at second , third , x, item of a range .
My example :
SSL certificate expires in less than 30 days for instance A .
SSL certificate expires in less than 30 days for instance B.
SSL certificate expires in less than 30 days for instance C .
SSL certificate expires in less than 30 days for instance D.
No idea , how to get rid of it .
I changed the definition of text to take only description annotations in template but unfortunately it doesn't work .
{{/* The text to display in the alert */}}
{{ define "slack.monzo.text" -}}
{{ range .Alerts }}
{{- if .Annotations.description }}
{{ .Annotations.description }}
{{- end }}
{{- end }}
{{- end }}
Have anyone ideas ?
@ioncoa Remove the indentation from the go template function. E.g.
{{/* The text to display in the alert */}}
{{ define "slack.monzo.text" -}}
{{ range .Alerts }}
{{- if .Annotations.description }}
{{ .Annotations.description }}
{{- end }}
{{- end }}
{{- end }}
Addition for Grafana Alerting integration with AlertManager:
ℹ️ You have to set alertmanger.externalUrl
to your Grafana instance external URL
{{ define "__grafana_alert_silence_link" -}}
{{ .ExternalURL }}/alerting/silence/new?
{{- range .CommonLabels.SortedPairs -}}
matcher={{- .Name }}%3D{{- .Value | urlquery -}}&
{{- end -}}
{{- end }}

Thanks @aorfanos
Have you also found a way to get the query button working towards Grafana? Alternatively, an external Prometheus?
Hello,
Thanks for sharing :)
In case you have built in Grafana Alerting/silence but also using Alertmanager as an additional Data source you have to append alertmanager=Alertmanager at the end of the url .
{{ define "__grafana_alert_silence_link" -}}
{{ .ExternalURL }}/alerting/silence/new?
{{- range .CommonLabels.SortedPairs -}}
matcher={{- .Name }}%3D{{- .Value | urlquery -}}&
{{- end -}}
alertmanager=Alertmanager
{{- end }}
P.S : tested on alertmanager 0.25 / grafana 9.1.6
Cheers
Hey everyone,
I want to share some findings as i tried to implement what is written here and got some insights that might help you:
-
name field for slack button:
if you dont specify a name for a slack button, you will only have 1 slack button as they need it to diffrenciate between the buttons in the list. here is where i found it in their documents: https://api.slack.com/legacy/interactive-message-field-guide -
if your button links to a url it must contain
http://
orhttps://
i had a button with:grafana.com
and it didn't work, only after i made ithttps://grafana.com
it worked. -
the advise by @80kk was crucial for the buttons, the
value: 'test'
field was mandatory for me to make it work.
so this is my configuration for working buttons:
- type: button
name: mutebutton
text: 'Mute :prometheus:'
value: 'text'
url: "https://{{ (index .Alerts 0).Labels.alertManagerUrl }}" # just a link for our internal alert manager, with added https://
- type: button
name: readmebutton
text: 'README :green_book:'
value: 'text'
url: "{{ (index .Alerts 0).Labels.readmeUrl }}" # just a link for our internal readme, it comes with https:// so no need to add
- type: button
name: grafana
text: 'Grafana :grafana:'
value: 'text'
url: 'https://{{ (index .Alerts 0).Labels.grafanaAlertUrl }}' # same as first button
and thanks everyone for all the comments here!
actions:
- type: button
text: 'README :green_book:'
url: '{{ (index .Alerts 0).Annotations.runbook_url }}'
- type: button
text: 'Query :mag:'
url: '{{ (index .Alerts 0).GeneratorURL }}'
- type: button
text: 'Dashboard :chart_with_upwards_trend:'
url: '{{ (index .Alerts 0).Annotations.dashboard_url }}'
- type: button
text: 'Silence :no_bell:'
url: '{{ template "__alert_silence_link" . }}'
EOF
I have my buttons set up like this and I can only get in Slack the "Runbook" one to be shown. Any idea why it's not showing the Query, Dashboard or Silence button as well?
I have tried the value: 'text' but it seems not to make a difference.
@stefaneacsu147 see my previous answer, you might need to add name:
field to each button.
hi guys how can use this? should you create docs dude
If someone has missing Silence button, then double check your alert name. If alert name has spaces, then your link is malformed.
You can use this template
{{ define "__alert_silence_link" -}}
{{ .ExternalURL }}/#/silences/new?filter=%7B
{{- range .CommonLabels.SortedPairs -}}
{{- if ne .Name "alertname" -}}
{{- .Name }}%3D"{{- .Value | urlquery -}}"%2C%20
{{- end -}}
{{- end -}}
alertname%3D"{{- .CommonLabels.alertname | urlquery -}}"%7D
{{- end }}
Notice .CommonLabels.alertname | urlquery
change in the end.
Buttons are going to disappear if you link is malformed (i.e. non-urlencoded spaces or other chars). The best way to check it is to add the same link to message text and check the result:
receivers:
- name: slack-receiver
slack_configs:
- channel: "#alerts" # slack channel for notrifications
send_resolved: true
color: '{{ template "slack.monzo.color" . }}'
title: '{{ template "slack.monzo.title" . }}'
text: '{{ template "slack.monzo.text" . }} LINK: `{{ template "__alert_silence_link" . }}` '
Hope this will help!
My case is there are too many labels value with a space " ",
this is how i solved it.
{{ define "__alert_silence_link" -}}
{{ .ExternalURL }}/#/silences/new?filter=%7B
{{- range .CommonLabels.SortedPairs -}}
{{- if ne .Name "alertname" -}}
{{- .Name }}%3D"{{- urlquery .Value | reReplaceAll "\\+" "%20" -}}"%2C%20
{{- end -}}
{{- end -}}
alertname%3D"{{- urlquery .CommonLabels.alertname | reReplaceAll "\\+" "%20" -}}"%7D
{{- end }}
Hope this will help solving the same case
Thank for the template, I managed to adjust it to our needs.
Is there any way to add a hostname or IP address to the alert?
I've been trying the following method, then use
.Labels.ip
in the template but it doesn't work.The above solution simply prints
{{ $ip }}
as a text.It'd be helpful if I could preview the full message payload that's being sent from Alert Manager, but seems like it's not possible.
Any ideas?
