To create a log analytics report for resource changes that were done manually, you can use the Azure Monitor Change Analysis feature.
Here are the steps to create a log analytics report for resource changes that were done manually:
Go to the Azure portal and navigate to the Log Analytics workspace that you want to use for the report.
Click on "Logs" in the left-hand menu.
In the query editor, enter the following query:
AzureActivity
| where OperationNameValue == "Microsoft.Resources/deployments/write"
| where ActivityStatus == "Succeeded"
| where ResourceProviderValue == "Microsoft.Resources"
| where ResourceGroup != ""
| where Caller != ""
| where DeploymentName != ""
| where DeploymentStatus == "Succeeded"
| where DeploymentScope == "ResourceGroup"
| where DeploymentType == "Incremental"
| where DeploymentTemplateLink.uri != ""
| where DeploymentTemplateLink.uri contains "https://management.azure.com/"
| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/deployments/"
| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/subscriptions/"
| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/resourceGroups/"
| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/providers/"
| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/policyDefinitions/"
| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/policyAssignments/"

| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/managedBy/"
| where DeploymentTemplateLink.uri !contains "/providers/Microsoft.Resources/aliases/"
| project TimeGenerated, Caller, ResourceGroup, DeploymentName, DeploymentTemplateLink.uri
This query will return a list of all successful deployments that were done manually.
