[Transformations in Azure Monitor](/azure/azure-monitor/data-collection/data-collection-transformations) allow you to filter or modify incoming data before it's stored in a Log Analytics workspace. They're implemented as a Kusto Query Language (KQL) statement in a [data collection rule (DCR)](/azure/azure-monitor/data-collection/data-collection-rule-overview). Learn more about how to [create workspace transformations](/azure/azure-monitor/data-collection/data-collection-transformations-create?tabs=portal#create-workspace-transformation-dcr) and the [cost for transformations](/azure/azure-monitor/data-collection/data-collection-transformations#cost-for-transformations).

### Transform away rows sent to Log Analytics

The `ThreatIntelIndicators` table always receives at least one row for each unexpired indicator. In some cases, the STIX pattern cannot be parsed into key/value pairs. When this happens, the indicator is still sent to Log Analytics, but only the raw, unparsed pattern is included—allowing users to build custom analytics if needed. If these rows are not useful for your scenario, you can filter them out before ingestion using the following KQL statement:
