Hello,
I'm following the suggestions I got from here
<https://docs.aws.amazon.com/prometheus/latest/userguide/AMP-alertmanager-receiver-JSON.html>
from AWS in order to convert the Alert Manager message into JSON so I can
use it in SNS.
Basically, I'm defining a template for SNS message like this:
* {{ define "sns.default.message" }}{{ "{" }}"receiver": "{{ .Receiver
}}","status": "{{ .Status }}","alerts": [{{ range $alertIndex, $alerts :=
.Alerts }}{{ if $alertIndex }}, {{ end }}{{ "{" }}"status": "{{
$alerts.Status }}"{{ if gt (len $alerts.Labels.SortedPairs) 0 -}},"labels":
{{ "{" }}{{ range $index, $label := $alerts.Labels.SortedPairs }}{{ if
$index }}, {{ end }}"{{ $label.Name }}": "{{ $label.Value }}"{{ end }}{{
"}" }}{{- end }}{{ if gt (len $alerts.Annotations.SortedPairs ) 0
-}},"annotations": {{ "{" }}{{ range $index, $annotations :=
$alerts.Annotations.SortedPairs }}{{ if $index }}, {{ end }}"{{
$annotations.Name }}": "{{ $annotations.Value }}"{{ end }}{{ "}" }}{{- end
}},"startsAt": "{{ $alerts.StartsAt }}","endsAt": "{{ $alerts.EndsAt
}}","generatorURL": "{{ $alerts.GeneratorURL }}","fingerprint": "{{
$alerts.Fingerprint }}"{{ "}" }}{{ end }}]{{ if gt (len .GroupLabels) 0
-}},"groupLabels": {{ "{" }}{{ range $index, $groupLabels :=
.GroupLabels.SortedPairs }}{{ if $index }}, {{ end }}"{{ $groupLabels.Name
}}": "{{ $groupLabels.Value }}"{{ end }}{{ "}" }}{{- end }}{{ if gt (len
.CommonLabels) 0 -}},"commonLabels": {{ "{" }}{{ range $index,
$commonLabels := .CommonLabels.SortedPairs }}{{ if $index }}, {{ end }}"{{
$commonLabels.Name }}": "{{ $commonLabels.Value }}"{{ end }}{{ "}" }}{{-
end }}{{ if gt (len .CommonAnnotations) 0 -}},"commonAnnotations": {{ "{"
}}{{ range $index, $commonAnnotations := .CommonAnnotations.SortedPairs
}}{{ if $index }}, {{ end }}"{{ $commonAnnotations.Name }}": "{{
$commonAnnotations.Value }}"{{ end }}{{ "}" }}{{- end }}{{ "}" }}{{ end }}*
The only problem I'm facing now is that the double quotes (") are not being
properly escaped so the JSON structure is broken. Any suggestion about what
to do in this case?
My options are the following functions
<https://prometheus.io/docs/alerting/latest/notifications/>:
- *safeHtml*: it didn't escape the double-quoted
- *reReplaceAll*: I didn't manage to properly use it. Any example?
Any other option you can think of?
Thanks,
Emmanuel
