Azure Blob Storage Container Files

Question

Hi, Is their a way to monitor a blob storage container has received a file and then also monitor if the file is in archived folder once it has been processed?

Answer 1

Hello Kranti,

You can create a custom KQL query to fetch the relevant logs and enable alerts using that query. Run the query in the Log Analytics workspace to retrieve the desired logs, and then set up alerts based on the query results.

Hello Kranthi,

try this

StorageBlobLogs

| where OperationName == "PutBlob" or OperationName == "PutBlockList"

| where ContainerName == "your-container-name"

| project TimeGenerated, BlobName, ContainerName, CallerIpAddress, ResultType, RequestId

| order by TimeGenerated desc

StorageBlobLogs

| where OperationName == "PutBlob" or OperationName == "PutBlockList"

| where ContainerName == "your-container-name" and BlobName startswith "archive/"

| project TimeGenerated, BlobName, ContainerName, CallerIpAddress, ResultType, RequestId

| order by TimeGenerated desc

let me know if this works or i will work on it.

Hi Kranthi - Thanks for reaching out over Q&A Forum

In order to check for operation happening on the account, you need to first enable the diagnostic logging on the account.

Once done, you can then leverage the KQL queries in order query as per your operation requirement.

Hope that helps!

Hi @Kranthi

Welcome to Microsoft Q&A, thanks for posting your query.

Adding additional information for the above answer.

Yes, you can monitor a blob storage container for file uploads and track the movement of files to an archived folder after processing.

To monitor when a file is uploaded to a blob storage container, you can use Azure Event Grid. Blob storage events are pushed using Azure Event Grid to subscribers such as Azure Functions, Azure Logic Apps, or even to your own http listener. Event Grid provides reliable event delivery to your applications through rich retry policies and dead lettering.

This service allows you to react to events such as the creation of blobs in your storage container. By setting up an event subscription, you can trigger Azure Functions or other services to execute code in response to these events.

Once a file has been processed, you can move it to an archived folder within the blob storage. You can continue to monitor this archived folder using similar event-driven architecture to detect when files are moved or accessed.
