See Monitor Azure Blob Storage for details on the data you can collect for Azure Blob Storage and how to use it.
[!INCLUDE horz-monitor-ref-metrics-intro]
The following table lists the metrics available for the Microsoft.Storage/storageAccounts resource type. [!INCLUDE horz-monitor-ref-metrics-tableheader] [!INCLUDE Microsoft.Storage/storageAccounts]
| Metric | Name in REST API | Unit | Aggregation | Dimensions | Time Grains | DS Export |
|---|---|---|---|---|---|---|
| Pending Bytes for Replication (preview) The size in bytes of the blob object pending for replication. | PendingBytesForReplication | Bytes | Average Minimum, Maximum | TimeBucket, AccountName, and PolicyId | PT2M | No |
| Pending Operations for Replication (preview) The count of pending operations for replication. | PendingOperationsForReplication | Count | Average Minimum, Maximum | TimeBucket, AccountName, and PolicyId | PT2M | No |
The following table lists the metrics available for the Microsoft.Storage/storageAccounts/blobServices resource type. [!INCLUDE horz-monitor-ref-metrics-tableheader] [!INCLUDE Microsoft.Storage/storageAccounts/blobServices]
Note
The Blob Capacity and Blob Count metric are emitted hourly. A background process computes these metrics and updates them multiple times a day.

[!INCLUDE Metrics dimensions]
| Dimension Name | Description |
|---|---|
| BlobType | The type of blob for Blob metrics only. The supported values are BlockBlob, PageBlob, and Azure Data Lake Storage. Append blobs are included in BlockBlob. |
| Tier | Azure storage offers different access tiers, which allow you to store blob object data in the most cost-effective manner. See more in Azure Storage blob tier. The supported values include: Hot: Hot tier Cool: Cool tier Cold: Cold tier Archive: Archive tier Premium: Premium tier for block blob P4/P6/P10/P15/P20/P30/P40/P50/P60: Tier types for premium page blob Standard: Tier type for standard page Blob Untiered: Tier type for general purpose v1 storage account |
For the metrics supporting dimensions, you need to specify the dimension value to see the corresponding metrics values. For example, if you look at Transactions value for successful responses, you need to filter the ResponseType dimension with Success. If you look at BlobCount value for Block Blob, you need to filter the BlobType dimension with BlockBlob.

The following sections describe the properties for Azure Storage resource logs when they're collected in Azure Monitor Logs or Azure Storage. The properties describe the operation, the service, and the type of authorization that was used to perform the operation.
Note
The field names listed in each section below are valid when resource logs are sent to Azure storage or to an event hub. When the logs are sent to a Log Analytics workspace, the field names might be different.
