-| Collect only critical resource log data from Azure resources. | When you create [diagnostic settings](essentials/diagnostic-settings.md) to send [resource logs](essentials/resource-logs.md) for your Azure resources to a Log Analytics database, only specify those categories that you require. Since diagnostic settings don't allow granular filtering of resource logs, use a [workspace transformation](essentials/data-collection-transformations.md?#workspace-transformation-dcr) to further filter unneeded data. See [Diagnostic settings in Azure Monitor](essentials/diagnostic-settings.md#controlling-costs) for details on how to configure diagnostic settings and using transformations to filter their data. |
