 ## Workspace reached ingestion volume rate limit
 The [default ingestion volume rate limit](../service-limits.md#log-analytics-workspaces) for data sent from Azure resources using diagnostic settings is approximately 6 GB/min per workspace. This is an approximate value because the actual size can vary between data types, depending on the log length and its compression ratio. This limit doesn't apply to data that's sent from agents or the [Logs ingestion API](logs-ingestion-api-overview.md). 
 
-If you send data at a higher rate to a single workspace, some data is dropped, and an event is sent to the **Operation** table in your workspace every six hours while the threshold continues to be exceeded. If your ingestion volume continues to exceed the rate limit or you are expecting to reach it sometime soon, you can request an increase to your workspace by sending an email to [email protected] or by opening a support request.
