They are sensitive on the latency of the message, and sometimes they need to track the message in a few connections instead of all the connections for some reason. + +Therefore, SignalR service provides two kinds of collecting behaviors +* **collect all**: collect logs in all connections +* **collect partially**: collect logs in some specific connections + +> To distinguish the connections between those collect logs and those don't collect logs, SignalR service will treat some client as diagnostic client based on the diagnostic client configurations of server and client, in which the diagnostic logs always get collected, while the others don't.

The server controls which client can be a diagnostic client. Once a client is marked as a diagnostic client, all diagnostic logs will be enabled in this client.

For example, make client with hub URL `?diag=yes`, then setup `ServiceOptions.DiagnosticClientFilter` to filter the diagnostic client. If it returns `true`, the client will be marked as diagnostic client; otherwise, it keeps as normal client. The `ServiceOptions.DiagnosticClientFilter` can be set in your startup class like this: + +``` +// sample: mark a client as diagnostic client when it has query string "?diag=yes" in hub URL +public IServiceProvider ConfigureServices(IServiceCollection services) +{ + services.AddMvc(); + services + .AddSignalR() + .AddAzureSignalR(o => + { + o.ConnectionString = ""; + o.DiagnosticClientFilter = context => context.Request.Query["diag"] == "yes"; + }); + + return services.BuildServiceProvider(); +} +``` +###### Client side + +Mark the client as diagnostic client by configuring the http context.

See the next sections about how to troubleshoot. -#### Unexpected connection number changes +##### Unexpected connection number changes -##### Unexpected connection dropping +###### Unexpected connection dropping If you encounter unexpected connections drop, firstly enable logs in service, server and client sides. @@ -176,28 +259,115 @@ Service reloading, please reconnect | Azure SignalR Service is reloading. Azure Internal server transient error | Transient error occurs in Azure SignalR Service, should be auto-recovered Server connection dropped | Server connection drops with unknown error, consider self-troubleshooting with service/server/client side log first. Try to exclude basic issues (e.g Network issue, app server side issue, etc.). If the issue isn't resolved, contact us for further help. For more information, see [Get help](get-help) section. -##### Unexpected connection growing +###### Unexpected connection growing To troubleshoot about unexpected connection growing, the first thing you need to do is filter out the extra connections. You can add unique test user ID to your test client connection. Then verify it in with diagnostic logs, you see more than one client connections have the same test user ID or IP, then it is likely the client side create and establish more connections than expectation. Check your client side. -#### Authorization failure +##### Authorization failure If you get 401 Unauthorized returned for client requests, check your diagnostic logs. If you encounter `Failed to validate audience. Expected Audiences: . Actual Audiences: `, it means your all audiences in your access token is invalid. Try to use the valid audiences suggested in the log. -#### Throttling +##### Throttling If you find that you cannot establish SignalR client connections to Azure SignalR Service, check your diagnostic logs. If you encounter `Connection count reaches limit` in diagnostic log, you establish too many connections to SignalR Service, which reach the connection count limit. Consider scaling up your SignalR Service. If you encounter `Message count reaches limit` in diagnostic log, it means you use free tier, and you use up the quota of messages. If you want to send more messages, consider changing your SignalR Service to standard tier to send additional messages. For more details, see [Azure SignalR Service Pricing](https://azure.microsoft.com/en-us/pricing/details/signalr-service/). +#### Message related issues + +When encountering message related problem, you can take advantage of messaging logs to troubleshoot. Firstly, [enable diagnostic logs](#enable-diagnostic-logs) in service, logs for server and client. + +> For ASP.NET Core, see [here](https://docs.microsoft.com/aspnet/core/signalr/diagnostics) to enable logging in server and client. +> +> For ASP.NET, see [here](https://docs.microsoft.com/aspnet/signalr/overview/testing-and-debugging/enabling-signalr-tracing) to enable logging in server and client. + +If you don't mind potential performance impact and no client-to-server direction message, check the `Messaging` in `Log Source Settings/Types` to enable *collect-all* log collecting behavior. For more information about this behavior, see [collect all section](#collect-all). + +Otherwise, uncheck the `Messaging` to enable *collect-partially* log collecting behavior. This behavior requires configuration in client and server to enable it. For more information, see [collect partially section](#collect-partially). + +##### Message loss + +If you encounter message loss problem, the key is to locate the place where you lose the message. Basically, you have 3 components when using SignalR service: SignalR service, server and client. Both server and client are connected to SignalR service, they don't connected to each other directly once negotiation is completed. Therefore, we need to consider 2 directions for messages, for each direction, we need to consider 2 paths: + +* From client to server via SignalR service + * Path 1: Client to SignalR service + * Path 2: SignalR service to server +* From server to client via SignalR service + * Path 3: Server to SignalR service + * Path 4: SignalR service to client + +![Message path](./images/diagnostic-logs/message-path.png) + +For **collect all** collecting behavior: + +SignalR service only trace messages in direction **from server to client via SignalR service**. The tracing ID will be generated in server, the message will carry the tracing ID to SignalR service. + +> If you want to trace message and [send messages from outside a hub](https://docs.microsoft.com/en-us/aspnet/core/signalr/hubcontext) in your app server, you need to enable **collect all** collecting behavior to collect message logs for the messages which are not originated from diagnostic clients. +> Diagnostic clients works for both **collect all** and **collect partially** collecting behaviors. It has higher priority to collect logs. For more information, see [diagnostic client section](#diagnostic-client). + +By checking the log in server and service side, you can easily find out whether the message is sent from server, arrives at SignalR service, and leaves from SignalR service. Basically, by checking if the *received* and *sent* message are matched or not based on message tracing Id, you can tell whether the message loss issue is in server or SignalR service in this direction. For more information, see the [details](#message-flow-detail-for-path3) below. + +For **collect partially** collecting behavior: + +Once you mark the client as diagnostic client, SignalR service will trace messages in both directions. + +By checking the log in server and service side, you can easily find out whether the message is pass the server or SignalR service successfully. Basically, by checking if the *received* and *sent* message are matched or not based on message tracing Id, you can tell whether the message loss issue is in server or SignalR service. For more information, see the details below. + +**Details of the message flow** + +For the direction **from client to server via SignalR service**, SignalR service will **only** consider the invocation that is originated from diagnostic client, that is, the message generated directly in diagnostic client, or service message generated due to the invocation of diagnostic client indirectly. + +The tracing ID will be generated in SignalR service once the message arrives at SignalR service in **Path 1**. SignalR service will generate a log `Received a message from client connection .` for each message in diagnostic client. Once the message leaves from the SignalR to server, SignalR service will generate a log `Sent a message to server connection successfully.` If you see these 2 logs, you can be sure that the message passes through SignalR service successfully. + +> Due to the limitation of ASP.NET Core SignalR, the message comes from client doesn't contains any message level ID. But ASP.NET SignalR generate *invocation ID* for each message, you can use it to map with the tracing ID. + +Then the message carries the tracing ID Server in **Path 2**. Server will generate a log `Received message from client connection ` once the message arrives. + + +Once the message invokes the hub method in server, a new service message will be generated with a *new tracing ID*. Once the service message is generated, server will generate a log in template `Start to broadcast/send message ...`, the actual log will be based on your scenario. Then the message will be delivered to SignalR service in **Path 3**, once the service message leaves from server, a log called `Succeeded to send message ` will be generated. + +> The tracing ID of the message from client cannot map to the tracing ID of the service message to be sent to SignalR service. + +Once the service message arrives at SignalR service, a log called `Received a message from server connection .` will be generated. Then SignalR service processes the service message and deliver to the target client(s). Once the message is sent to client(s) in **Path 4**, log `Sent a message to client connection successfully.` will be generated. + +In summary, the message log will be generated when message goes in and out the SignalR service and server. You can use these logs to validate whether the message is lost in these components or not. + +Below is a typical message loss issue. + +###### A client fails to receive messages in a group + +The typical story in this issue is that the client joins a group **after** sending a group message. + +``` +Class Chat : Hub +{ + public void JoinAndSendGroup(string name, string groupName) + { + Groups.AddToGroupAsync(Context.ConnectionId, groupName); // join group + Clients.Group(groupName).SendAsync("ReveiceGroupMessage", name, "I'm in group"); // send group message + } +} +``` + +For example, someone may make invocations of *join group* and *send group message* in the same hub method. The problem here is the `AddToGroupAsync` is an `async` method. There's no `await` for the `AddToGroupAsync` to wait it finishes, the group message sent before `AddToGroupAsync` completes. Due to network delay, and the delay of the process of joining client to some group, the join group action may complete later than group message delivery. If so, the first group message won't have any client as receiver, since no client has joined the group. So it'll become a message lost issue. + +Without diagnostic logs, you are unable to find out when the client joins the group and when the group message is sent. +Once you enable messaging logs, you are able to compare the message arriving time in SignalR service. Follow the below steps to troubleshoot: +1. Find the message logs in server to find when the client joined the group and when the group message is sent. +1. Get the message tracing ID A of joining the group and the message tracing ID B of group message from the message logs. +1. Filter these message tracing ID among messaging logs in your log archive target, then compare their arriving timestamps, you will find which message message is arrived first in SignalR service. +1. If message tracing ID A's arriving time later than B's, then you must be sending group message **before** the client joining the group.Then you need to make sure the client is in the group before sending group messages. + +If a message get lost in SignalR or server, try to get the warning logs based on the message tracing ID to get the reason.

If the URL is targeting to your web app, and similar to `{your_web_app}/hubs/{hubName}`, check if the client `SkipNegotiation` is `true`. When using Azure SignalR, the client receives redirect URL when it first negotiates with the app server. The client should **NOT** skip negotiation when using Azure SignalR. -1. Another 404 can happen when the connect request is handled more than **5** seconds after `/negotiate` is called. Check the timestamp of the client request, and open an issue to us if the request to the service has a very slow response. - - -## 404 returned for ASP.NET SignalR's reconnect request -For ASP.NET SignalR, when the [client connection drops](#client_connection_drop), it reconnects using the same `connectionId` for 3 times before stopping the connection. `/reconnect` can help if the connection is dropped due to network intermittent issues that `/reconnect` can reestablish the persistent connection successfully. Under other circumstances, for example, the client connection is dropped due to the routed server connection is dropped, or SignalR Service has some internal errors like instance restart/failover/deployment, the connection no longer exists, thus `/reconnect` returns `404`. It is the expected behavior for `/reconnect` and after 3 times retry the connection stops. We suggest having [connection restart](#restart_connection) logic when connection stops. - - -## 413 returned for REST API requests - -413 returns if your request body is larger than 1MB. - -For REST API see [limitation](rest-api.md#Limitation). - - -## 429(Too Many Requests) returned for client requests - -There are two cases. - -### **Concurrent** connection count exceeds limit. - -* For **Free** instances, **Concurrent** connection count limit is 20. -* For **Standard** instances, **concurrent** connection count limit **per unit** is 1K, which means Unit100 allows 100K **concurrent** connections. - -The connections include both client and server connections. -Check [here](https://docs.microsoft.com/en-us/azure/azure-signalr/signalr-concept-messages-and-connections#how-connections-are-counted) for how connections are counted. - -### Too many negotiate requests at the same time. - -We suggest having a random delay before reconnecting, please check [here](#restart_connection) for retry samples. - - -## 500 Error when negotiate: Azure SignalR Service is not connected yet, please try again later. -### Root cause -This error is reported when there is no server connection to Azure SignalR Service connected. - -### Troubleshooting Guide -Please enable server-side trace to find out the error details when the server tries to connect to Azure SignalR Service. - -#### Enable server side logging for ASP.NET Core SignalR -Server side logging for ASP.NET Core SignalR integrates with the `ILogger` based [logging](https://docs.microsoft.com/en-us/aspnet/core/fundamentals/logging/?view=aspnetcore-2.1&tabs=aspnetcore2x) provided in the ASP.NET Core framework. You can enable server side logging by using `ConfigureLogging`, a sample usage as follows: -```cs -.ConfigureLogging((hostingContext, logging) => - { - logging.AddConsole(); - logging.AddDebug(); - }) -``` -Logger categories for Azure SignalR always starts with `Microsoft.Azure.SignalR`. To enable detailed logs from Azure SignalR, configure the preceding prefixes to `Debug` level in your **appsettings.json** file like below: -```JSON -{ - "Logging": { - "LogLevel": { - ... - "Microsoft.Azure.SignalR": "Debug", - ... - } - } -} -``` - -#### Enable server side traces for ASP.NET SignalR -When using SDK version >= `1.0.0`, you can enable traces by adding the following to `web.config`: ([Details](https://github.com/Azure/azure-signalr/issues/452#issuecomment-478858102)) -```xml - - - - - - - - - - - - - - - - - - -``` - -## Client connection drops - -When the client is connected to the Azure SignalR, the persistent connection between the client and Azure SignalR can sometimes drop for different reasons. This section describes several possibilities causing such connection drop and provides some guidance on how to identify the root cause. - -### Possible errors seen from the client-side -1. `The remote party closed the WebSocket connection without completing the close handshake` -2. `Service timeout. 30.00ms elapsed without receiving a message from service.` -3. `{"type":7,"error":"Connection closed with an error."}` -4. `{"type":7,"error":"Internal server error."}` - -### Root cause: -Client connections can drop under various circumstances: -1. When `Hub` throws exceptions with the incoming request. -2. When the server connection the client routed to drops, see below section for details on [server connection drops](#server_connection_drop). -3. When a network connectivity issue happens between client and SignalR Service. -4. When SignalR Service has some internal errors like instance restart, failover, deployment, and so on. - -### Troubleshooting Guide -1. Open app server-side log to see if anything abnormal took place -2. Check app server-side event log to see if the app server restarted -3. Create an issue to us providing the time frame, and email the resource name to us - - - -## Client connection increases constantly -It might be caused by improper usage of client connection. If someone forgets to stop/dispose SignalR client, the connection remains open. - -### Possible errors seen from the SignalR's metrics blade -Client connections rise constantly for a long time in Azure SignalR's metrics blade. -![client_connection_increasing_constantly](./images/client_connection_increasing_constantly.jpg) - -### Root cause: -SignalR client connection's `DisposeAsync` never be called, the connection keeps open. - -### Troubleshooting Guide -1. Check if the SignalR client **never** close. - -### Solution -Check if you close connection. Please manually call `HubConnection.DisposeAsync()` to stop the connection after using it. - -For example: - -```C# -var connection = new HubConnectionBuilder() - .WithUrl(...) - .Build(); -try -{ - await connection.StartAsync(); - // Do your stuff - await connection.StopAsync(); -} -finally -{ - await connection.DisposeAsync(); -} -``` - -### Common Improper Client Connection Usage - -#### Azure Function Example -This issue often occurs when someone establishes SignalR client connection in Azure Function method instead of making it a static member to your Function class. You might expect only one client connection is established, but you see client connection count increases constantly in metrics blade, all these connections drop only after the Azure Function or Azure SignalR service restarts. This is because for **each** request, Azure Function creates **one** client connection, if you don't stop client connection in Function method, the client keeps the connections alive to Azure SignalR service. - -#### Solution -1. Remember to close client connection if you use SignalR clients in Azure function or use SignalR client as a singleton. -1. Instead of using SignalR clients in Azure function, you can create SignalR clients anywhere else and use [Azure Functions Bindings for Azure SignalR Service](https://github.com/Azure/azure-functions-signalrservice-extension) to [negotiate](https://github.com/Azure/azure-functions-signalrservice-extension/blob/dev/samples/simple-chat/csharp/FunctionApp/Functions.cs#L22) the client to Azure SignalR. And you can also utilize the binding to [send messages](https://github.com/Azure/azure-functions-signalrservice-extension/blob/dev/samples/simple-chat/csharp/FunctionApp/Functions.cs#L40). Samples to negotiate client and send messages can be found [here](https://github.com/Azure/azure-functions-signalrservice-extension/tree/dev/samples). Further information can be found [here](https://github.com/Azure/azure-functions-signalrservice-extension). -1. When you use SignalR clients in Azure function, there might be a better architecture to your scenario. Check if you design a proper serverless architecture. You can refer to [Real-time serverless applications with the SignalR Service bindings in Azure Functions](https://www.nuget.org/packages/Microsoft.Azure.WebJobs.Extensions.SignalRService). - - -## Server connection drops - -When the app server starts, in the background, the Azure SDK starts to initiate server connections to the remote Azure SignalR. As described in [Internals of Azure SignalR Service](internal.md), Azure SignalR routes incoming client traffics to these server connections. Once a server connection is dropped, all the client connections it serves will be closed too. - -As the connections between the app server and SignalR Service are persistent connections, they may experience network connectivity issues. In the Server SDK, we have **Always Reconnect** strategy to server connections. As the best practice, we also encourage users to add continuous reconnect logic to the clients with a random delay time to avoid massive simultaneous requests to the server. - -On a regular basis there are new version releases for the Azure SignalR Service, and sometimes the Azure wide OS patching or upgrades or occasionally interruption from our dependent services. These may bring in a very short period of service disruption, but as long as client-side has the disconnect/reconnect mechanism, the impact is minimal like any client-side caused disconnect-reconnect. - -This section describes several possibilities leading to server connection drop and provides some guidance on how to identify the root cause. - -### Possible errors seen from server-side: -1. `[Error]Connection "..." to the service was dropped` -2. `The remote party closed the WebSocket connection without completing the close handshake` -3. `Service timeout. 30.00ms elapsed without receiving a message from service.` - -### Root cause: -Server-service connection is closed by **ASRS**(**A**zure **S**ignal**R** **S**ervice). - -### Troubleshooting Guide -1.
