允许普罗米修斯警报管理器接收器字段中的模板化字段

Question

我正在尝试实现Brian Brazil在这里的建议：

https://www.robustperception.io/using-labels-to-direct-email-notifications/

我正在做的是将 OpenShift 命名空间注释获取到我的指标中，然后使用 Alertmanager 配置获取该标签。但它似乎不起作用，并抱怨"to"字段为空。

time="2018-06-26T13:28:48Z" level=debug msg="Notify attempt 1 for "email" failed: parsing to addresses: mail: no address" source="notify.go:585" 
time="2018-06-26T13:28:48Z" level=error msg="Error on notify: Cancelling notify retry for "email" due to unrecoverable error: parsing to addresses: mail: no address" source="notify.go:283" 
time="2018-06-26T13:28:48Z" level=error msg="Notify for 6 alerts failed: Cancelling notify retry for "email" due to unrecoverable error: parsing to addresses: mail: no address" source="dispatch.go:262" 

以下是我尝试过的一些配置：

# default route if none match
group_by: [annotation_contact_email]
receiver: projectalerts
group_by: []
group_wait: 0s
group_interval: 2s
repeat_interval: 2s
receivers:
- name: alert-buffer-wh
webhook_configs:
- url: http://localhost:9099/topics/alerts 
- name: projectalerts
email_configs:
- to: '{{.GroupLabels.annotation_contact_email}}'

还有

- name: projectalerts
email_configs:
- to: '{{.Labels.annotation_contact_email}}'

它适用于静态定义的电子邮件。

我终于使用它了：

global:
# The root route on which each incoming alert enters.
route:
# default route if none match
group_by: [annotation_contact_email]
receiver: projectalerts
# The labels by which incoming alerts are grouped together. For example,
# multiple alerts coming in for cluster=A and alertname=LatencyHigh would
# be batched into a single group.
# TODO:
#group_by: []
group_wait: 0s
group_interval: 5s
repeat_interval: 3600s
# All the above attributes are inherited by all child routes and can
# overwritten on each.
receivers:
- name: alert-buffer-wh
webhook_configs:
- url: http://localhost:9099/topics/alerts
- name: projectalerts
email_configs:
- to: "{{ .GroupLabels.annotation_contact_email }}"
