-
- Configuration can be performed using CLI or REST requests currently. Azure portal or PowerShell are not supported yet.
33
-
- The ```--export-all-tables``` option in CLI and REST isn't supported and will be removed. You should provide the list of tables in export rules explicitly.
34
-
- Supported tables are currently limited those specific in the [supported tables](#supported-tables) section below. For example, custom log tables aren't supported currently.
35
-
- If the data export rule includes an unsupported table, the operation will succeed, but no data will be exported for that table until table gets supported.
36
-
- If the data export rule includes a table that doesn't exist, it will fail with error ```Table <tableName> does not exist in the workspace```.

- Data export will be available in all regions, but currently not available in the following: Azure Government regions, Japan West, Brazil south east, Norway East, Norway West, UAE North, UAE Central, Australia Central 2, Switzerland North, Switzerland West, Germany West Central, South India, France South, Japan West

Data export will continue to retry sending data for up to 30 minutes in the event that the destination is unavailable. If it's still unavailable after 30 minutes then data will be discarded until the destination becomes available.

There are currently no additional charges for the data export feature. Pricing for data export will be announced in the future and a notice provided prior to start of billing. If you choose to continue using data export after the notice period, you will be billed at the applicable rate.

> The [number of supported event hubs per 'Basic' and 'Standard' namespaces tiers is 10](../../event-hubs/event-hubs-quotas.md#common-limits-for-all-tiers).

Considerations:

-
1. 'Basic' event hub tier supports lower [event size](../../event-hubs/event-hubs-quotas.md) and some logs in your workspace can exceed it and be dropped. We recommend to use 'Standard' or 'Dedicated' event hub as export destination.
70
-
2. The volume of exported data often increase over time, and the event hub scale needs to be increased to handle larger transfer rates and avoid throttling scenarios and data latency. You should use the auto-inflate feature of Event Hubs to automatically scale up and increase the number of throughput units and meet usage needs. See [Automatically scale up Azure Event Hubs throughput units](../../event-hubs/event-hubs-auto-inflate.md) for details.

- Destinations must be created prior to the export rule configuration and should be in the same region as your Log Analytics workspace. If you need to replicate your data to other storage accounts, you can use any of the [Azure Storage redundancy options](../../storage/common/storage-redundancy.md).

- The storage account must be StorageV1 or StorageV2. Classic storage is not supported
77

- If you have configured your storage account to allow access from selected networks, you need to add an exception in your storage account settings to allow Azure Monitor to write to your storage.
