Data collection rule should have data flows configured

High Azure General datacollectionrules-data-collection-rule-data

Applies to

Microsoft.Insights/dataCollectionRules

What CGPulse checks

A resource passes this rule when dataFlowsCount must be one of [1,2,3,4,5,6,7,8,9,10]. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Configure at least one data flow to route collected data to monitoring destinations. In Azure Portal: Monitor > Data Collection Rules > select rule > add data flow. See: https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/data-collection-rule-overview

CLI

az monitor data-collection rule show --ids "{id}" --query "dataFlows" -o table
