Alerting on Numeric Data not in humanized format

Grafana Alerting
1

Hi all, I’m trying to format my alert into more readable format but I’m unsuccessful as none of the following options are working:

  • {{ printf “%.0f” $values.B.Value }}%
  • {{humanizePercentage $values.E.value}}
  • {{humanize $values.D.value}}
  • {{ printf “%.0f” $values.B}}%
  • {{humanizePercentage $values.E}}
  • {{humanize $values.D}}

Actual Alert
Summary : This Week 8.177169330551363 seconds
Last Week 6.443039930620775 seconds
Description : Percentage last week by 26.914770335181025 %

Alert Preview: “[ var=‘E’ labels={metricId=1} value=-0.9789369886657984 ], [ var=‘C’ labels={metricId=1} value=24.807347163922728 ], [ var=‘B’ labels={metricId=1} value=24.56685315147176 ], [ var=‘D’ labels={metricId=1} value=0 ]”

Hi @arush361,
Something tells me that you are using Classic condition as an expression. :slight_smile: If that’s true try this:

Raw percentage: {{ $values.B0.Value }}
Human percentage : {{ humanizePercentage $values.B0.Value }}
Prometheus alert with Classic Condition expression

… or you can change from Classic condition to Reduce expression and then you would be able to use:

{{ printf "%.0f" $values.B.Value }}%

and

{{ humanizePercentage $values.B.Value }}
