Hi,
As you have guessed I want to know the time when the alert first started
firing.
I simply tried adding the alerting rules as in example :
- alert: InstanceDown
expr: up == 0
for: 5m
labels:
severity: critical
annotations:
timestamp: >
time: {{ .StartsAt }}
Which leaves me with the error:
= <error expanding template: error executing template __alert_InstanceDown:
template: __alert_InstanceDown:1:90: executing "__alert_InstanceDown" at
<.StartsAt>: can't evaluate field StartsAt in type struct { Labels
map[string]string; ExternalLabels map[string]string; Value float64 }>
Regards,
Sebastian
