-### Querying for data volumes excluding known free data types
-The following query will return the monthly data volume in GB, excluding all data types which are supposed to be free from data ingestion charges:
-
-```kusto
-let freeTables = dynamic([
-"AppAvailabilityResults","AppSystemEvents","ApplicationInsights","AzureActivity","AzureNetworkAnalyticsIPDetails_CL",
-"AzureNetworkAnalytics_CL","AzureTrafficAnalyticsInsights_CL","ComputerGroup","DefenderIoTRawEvent","Heartbeat",
-"MAApplication","MAApplicationHealth","MAApplicationHealthIssues","MAApplicationInstance","MAApplicationInstanceReadiness",
-"MAApplicationReadiness","MADeploymentPlan","MADevice","MADeviceNotEnrolled","MADeviceReadiness","MADriverInstanceReadiness",
-"MADriverReadiness","MAProposedPilotDevices","MAWindowsBuildInfo","MAWindowsCurrencyAssessment",
-"MAWindowsCurrencyAssessmentDailyCounts","MAWindowsDeploymentStatus","NTAIPDetails_CL","NTANetAnalytics_CL",
-"OfficeActivity","Operation","SecurityAlert","SecurityIncident","UCClient","UCClientReadinessStatus",
-"UCClientUpdateStatus","UCDOAggregatedStatus","UCDOStatus","UCDeviceAlert","UCServiceUpdateStatus","UCUpdateAlert",
-"Usage","WUDOAggregatedStatus","WUDOStatus","WaaSDeploymentStatus","WaaSInsiderStatus","WaaSUpdateStatus"]);
-Usage 
-| where DataType !in (freeTables) 
-| where TimeGenerated > ago(30d) 
-| summarize MonthlyGB=sum(Quantity)/1000
-```
-
-To look for data which might not have IsBillable correctly set (and which could result in incorrect billing, or more specifically under-billing), use this query on your workspace:
-
-```kusto
-let freeTables = dynamic([
-"AppAvailabilityResults","AppSystemEvents","ApplicationInsights","AzureActivity","AzureNetworkAnalyticsIPDetails_CL",
-"AzureNetworkAnalytics_CL","AzureTrafficAnalyticsInsights_CL","ComputerGroup","DefenderIoTRawEvent","Heartbeat",
-"MAApplication","MAApplicationHealth","MAApplicationHealthIssues","MAApplicationInstance","MAApplicationInstanceReadiness",
-"MAApplicationReadiness","MADeploymentPlan","MADevice","MADeviceNotEnrolled","MADeviceReadiness","MADriverInstanceReadiness",
-"MADriverReadiness","MAProposedPilotDevices","MAWindowsBuildInfo","MAWindowsCurrencyAssessment",
-"MAWindowsCurrencyAssessmentDailyCounts","MAWindowsDeploymentStatus","NTAIPDetails_CL","NTANetAnalytics_CL",
-"OfficeActivity","Operation","SecurityAlert","SecurityIncident","UCClient","UCClientReadinessStatus",
-"UCClientUpdateStatus","UCDOAggregatedStatus","UCDOStatus","UCDeviceAlert","UCServiceUpdateStatus","UCUpdateAlert",
-"Usage","WUDOAggregatedStatus","WUDOStatus","WaaSDeploymentStatus","WaaSInsiderStatus","WaaSUpdateStatus"]);
-Usage 
-| where DataType !in (freeTables) 
-| where TimeGenerated > ago(30d) 
-| where IsBillable == false 
-| summarize MonthlyPotentialUnderbilledGB=sum(Quantity)/1000 by DataType
-```

 ## Querying for common data types
 If you find that you have excessive billable data for a particular data type, you might need to perform a query to analyze data in that table. The following queries provide samples for some common data types:
