Hi,
Given rule
- alert: SnellIQModules
expr: ({state=~".*?FAIL.*?|.*?WARN.*?"})
for: 1s
labels:
alertname: snelliqmodulefail
severity: warning
annotations:
summary: "Module {{ $labels.instance }} state of {{ $labels.__name__
}} is {{ $labels.state }}"
description: "Module {{ $labels.instance }} state of {{
$labels.__name__ }} is {{ $labels.state }}"
in some cases this rule works as expected but in most cases I get "vector
contains metrics with the same labelset after applying alert labels" error
and I can't understand why.
When rule works ok I see query ({state=~".*?FAIL.*?|.*?WARN.*?"}) result in
Prometheus WEB interface:
ElementValue
snelltrapINPUT_2_CLOSED_CAPTION_STATE{dept="TV",instance="IQSAM00-3G
1",job="snelltrap",state="WARN:No"} 1
ALERTS_FOR_STATE{alertname="SnellIQModules",dept="TV",instance="IQSAM00-3G
1",job="snelltrap",severity="warning",state="WARN:No"} 1589688003
ALERTS{alertname="SnellIQModules",alertstate="firing",dept="TV",instance="IQSAM00-3G
1",job="snelltrap",severity="warning",state="WARN:No"} 1
When rule results error message "vector contains metrics with the same
labelset after applying alert labels" I see very similar result but it
causes an error:
ElementValue
snelltrapINPUT_2_CLOSED_CAPTION_STATE{dept="TV",instance="IQSAM00-3G
1",job="snelltrap",state="WARN:No"} 1
ALERTS_FOR_STATE{alertname="SnellIQModules",dept="TV",instance="IQSAM00-3G
