This article helps you investigate client application failures using metrics.client-side log filesand resource logs in Azure Monitor.
diagnose errors
Users of your application can notify you of errors reported by the client application. Azure Monitor also records the number of different response types (response typedimensions) from your storage services, such asnetwork error,ClientTimeoutError, orauthorization error. While Azure Monitor only records the number of different error types, you can get more detailed information about individual requests by examining server, client, and network logs. Usually, the HTTP status code returned by the storage service gives an indication of why the request failed.
Note
Remember to expect occasional errors. For example, errors due to transient network conditions or application errors.
The following resources are helpful in understanding memory-related status and error codes:
- Common REST API error codes
- Blob service error codes
- Error codes for queue service
- Table service error codes
- File service error codes
The client receives HTTP 403 (Forbidden) messages.
If your client application is throwing HTTP 403 (Forbidden) errors, the likely cause is that the client is using an expired Shared Access Signature (SAS) when sending a save request (although other possible causes include timing biases, invalid keys, and blanks). headings).
The Storage Client Library for .NET allows you to collect client-side log data related to storage operations performed by your application. For more information, seeClient-side logging using the .NET Storage Client Library.
The following table shows an example from the client-side log generated by the Storage Client Library that illustrates the occurrence of this issue:
| The there | details | details | Customer Request ID | Operationstekst |

In this scenario, you should investigate why the SAS token expires before the client sends the token to the server:
When you create a SAS, you should typically not specify a start time so that a client can start using it immediately. If there are small clock differences between the host generating the SAS with the current time and the storage service, it is possible that the storage service will receive a SAS that is not yet valid.
Do not set a very short expiration time on an SAS. Again, small clock differences between the host generating the SAS and the storage service can cause a SAS to expire sooner than expected.
Is the version parameter in the SAS key (eg
sv=2015-04-05) match the version of the Storage Client Library you are using? We recommend always using the latest version of the storage client library.If you regenerate your storage access keys, any existing SAS tokens may become invalid. This issue can occur when you generate SAS tokens with a long expiration time for client application caching.
Generating a valid token is easy when you use the Storage Client Library to generate SAS tokens. However, if you use the Storage REST API and create the SAS tokens manually, seeDelegation of access with a shared access signature.
The client receives HTTP 404 (Not Found) messages.
If the client application receives an HTTP 404 (Not Found) message from the server, it means that the object the client tried to access (such as an entity, table, blob, container, or queue) is not in the store that is a service. There are a number of possible reasons for this, such as:
The client or another process previously deleted the object.
Et problem med SAS-autorisation (Shared Access Signature).
(Video) How to troubleshoot temporary storage on Azure App ServiceClient-side JavaScript is not allowed to access the object.
network error.
The client or another process previously deleted the object
In scenarios where the client tries to read, update, or delete data in a storage service, it is easy to identify a previous action in the storage resource logs that deleted that object from the storage service. Often the log data shows that another user or process has deleted the object. The Azure Monitor logs (server side) show when a client has deleted an object.
In the scenario where a client tries to insert an object, it may not be immediately obvious why this results in an HTTP 404 (Not Found) response since the client is creating a new object. However, when the client creates a blob, it must be able to find the blob container. When the client writes a message, it must be able to find a queue. And when the client adds a row, it must be able to find the table.
You can use the client-side log from the Storage Client Library to better understand when the client makes specific requests to the storage service.
The following client-side log generated by the Storage Client library illustrates the problem when the client cannot find the container for the blob it is creating. This log contains details of the following storage operations:
| Request ID | Operation |
|---|---|
| 07b26a5d-... | DeleteIfExistsMethod to delete the blob container. This process includes aKOPFRequest to confirm the existence of the container. |
| e2d06d78… | CreateIfNotExistsMethod to create the blob container. This process includes aKOPFRequest that checks if the container exists. ThatKOPFreturns a 404 message but continues. |
| de8b1c3c-... | UploadFromStreamMethod to create the blob. ThatSETThe request fails with a 404 message |

In this example, the log shows that the client embeds requests fromCreateIfNotExistsmethod (request id e2d06d78...) with the requests fromUploadFromStreamMethod (de8b1c3c-...). This nesting occurs because the client application calls these methods asynchronously. Edit the asynchronous code in the client to ensure that it creates the container before attempting to upload data to a blob in this container. Ideally, you create all your containers in advance.
If the client application attempts to use a SAS key that does not contain the necessary permissions for the operation, the storage service returns an HTTP 404 (Not Found) message to the client. At the same time, a is also displayed in Azure Monitor metricsauthorization errorforresponse typeDimensions.
Investigate why your client application is trying to perform an action for which it has not been granted permissions.
Client-side JavaScript is not allowed to access the object
If you are using a JavaScript client and the storage service returns HTTP 404 messages, check for the following JavaScript errors in the browser:
SEC7120: Origin http://localhost:56309 ikke fundet i Access-Control-Allow-Origin header.
SCRIPT7002: XMLHttpRequest: Network error 0x80070005, access denied.
Note
You can use the F12 developer tools in Internet Explorer to trace the messages exchanged between the browser and the storage service when you debug client-side JavaScript problems.
These errors occur because the web browser implements itSame-origin policySecurity restriction that prevents a web page from calling an API on a domain other than the domain from which the page originated.
To work around the JavaScript issue, you can configure Cross-Origin Resource Sharing (CORS) for the storage service accessed by the client. For more information, seeCross-Origin Resource Sharing (CORS) support til Azure Storage Services.
The following code example shows how to configure your blob service to allow JavaScript to run in the Contoso domain to access a blob in your blob storage service:
- .NET v12 SDK
var ConnectionString = Constants.connectionString; BlobServiceClient blobServiceClient = ny BlobServiceClient(connectionString); BlobServiceProperties sp = blobServiceClient.GetProperties(); // Legen Sie die Diensteigenschaften fest. sp.DefaultServiceVersion = "2013-08-15"; BlobCorsRule bcr = new BlobCorsRule(); bcr.AllowedHeaders = "*"; bcr.AllowedMethods = "GET,POST"; bcr.AllowedOrigins = "http://www.contoso.com"; bcr.ExposedHeaders = "x-ms-*"; bcr.MaxAgeInSeconds = 5; sp.Cors.Clear(); sp.Cors.Add(bcr); blobServiceClient.SetProperties(sp);network error
Under certain circumstances, dropped network packets can cause the storage service to send HTTP 404 messages back to the client. If your client application e.g. deletes an entity from the table service, you will see the client throw a memory exception and report an "HTTP 404 (Not Found)" status message from the table service. If you examine the table in the table storage service, you will find that the service deleted the device as requested.
The exception details in the client include the request ID (7e84f12d...) assigned by the table service for the request: You can use this information to find the request details in the storage resource logs in Azure Monitor by searching themFields that describe how the action was approvedof log entries. You can also use metrics to identify when errors like this occur and then search the logs based on when metrics detected this error. This log entry shows that the deletion failed with the status message "HTTP (404) Client Other Error". The same log entry also contains the client-generated request ID imCustomer Request IDKolonne (813ea74f...).
The server-side log also contains another entry with the same entryCustomer Request IDValue (813ea74f...) for a successful delete operation for the same device and from the same client. This successful deletion happened just before the failed deletion request.
The most likely cause of this scenario is that the client sent an entity deletion request to the table service that was successful, but did not receive an acknowledgment from the server (possibly due to a temporary network problem). The client then automatically repeated the process (using the sameCustomer Request ID), and this retry failed because the device was already deleted.
If this problem occurs frequently, you should investigate why the client is not receiving receipts from table service. If the problem is intermittent, catch the HTTP (404) Not Found error and log in to the client, but allow the client to continue.
The client receives HTTP 409 (conflict) messages.
When a client deletes blob containers, tables, or queues, it takes a short time for the name to become available again. If the code in your client application deletes a blob container with the same name and then immediately recreates it, it willCreateIfNotExistsThe method eventually fails with an HTTP 409 (conflict) error.
The client application must use unique container names when creating new containers if the delete/restore pattern is common.
Metrics show low PercentSuccess or analysis log entries with operations with transaction status ClientOtherErrors.
INresponse typeDimension equal to a value ofSuccestracks the percentage of operations that were successful based on their HTTP status code. Operations with status codes of 2XX are considered successful, while operations with status codes in the 3XX, 4XX, and 5XX ranges are counted as failures and lower the success metric value. Storage resource logs record these operations with transaction statusClientOtherError.
These operations have been completed successfully and therefore do not affect other metrics such as: B. Availability. Some examples of operations that succeed but may result in failed HTTP status codes are:
- Resource not found(Not Found 404), for example from a GET request to a blob that doesn't exist.
- Resource already exists(Conflict 409), for example from a
CreateIfNotExistOperation where the resource already exists. - condition not met(Not Changed 304), for example from a conditional operation such as when a client sends a
ETagvalue and an HTTPif-not-matchHeader to only request an image if it has been updated since the last action.
