Azure Cosmos DB now supports transformations on your Log Analytics workspaces. To help reduce costs when enabling Log Analytics to perform detailed troubleshooting on your Cosmos DB resources, we’ve shipped transformations. Data collection rules makes this simple by allowing you to define rules on what data to collect and where it should be sent to, making it flexible enough to configure granular and targeted data collection, just the way you need to! These transformations on your Log Analytics workspace allow you to filter out columns, reduce the number of results returned, and create new columns before the data is sent to the destination.
