I am trying to monitor my spring boot application, which has actuator support.
And to be able to set a SpringBootAdmin server and client.
I enabled the shutdown endpoint in the client application by adding the
following to the application.properties file:
management.endpoint.shutdown.enabled=true
management.endpoints.web.exposure.include=health,metrics,loggers,httptrace,shutdown
Now I am able to hit the actuator shutdown api through the postman client and functionality is working fine.
Is there any way to get the shut down feature/tab in the spring boot admin UI?
Sadly, even 2 years later this is still not supported. You can list it inside management.endpoints.web.exposure.include as:
management.endpoints.web.exposure.include=shutdown
It will show up, but there is no option to action it.

I am implementing a VUE client app running on subdomain client.example.com and Laravel API on api.example.com. I am using webpush package to implement the browser notifications. I have my service worker (sw.js) on my vue app and manages to register the user, store the data to database on the push_notifications table.
The problem comes when I simulate the notification, it is not sent to the browser. I tend to think may be it is because the client app that requested for the permission is different from the API subdomain that triggers the notification.
Is there any way to implement this or my worries not realistic?
I have a question about CloudFoundry actuator endpoints in a .net core console application using Steeltoe. I am planning to use generic host https://jmezach.github.io/2017/10/29/having-fun-with-the-.net-core-generic-host/ to perform some background task. I would like to use few actuator endpoints e.g.Health actuator. I could find samples with WebHost here https://github.com/SteeltoeOSS/Samples/blob/dev/Management/src/AspDotNetCore/CloudFoundry/Startup.cs. The below code needs IApplicationBuilder
// Add management endpoints into pipeline
app.UseCloudFoundryActuators();
So it is possible to use actuator endpoints in a console application which is hosted by generic host. Any samples are most welcome. Thanks in advance.
Steeltoe 3.0 added a variety of extensions for using Management/Actuators with HostBuilder. Check out this file for some examples.
It would also be possible to add another implementation of the actuator endpoints that communicate over something other than HTTP (perhaps RabbitMQ as an example), Steeltoe Management was built with portable base endpoint functionality in mind - but then you would also need a new application for interacting with them, and you wouldn't be able to use them with Apps Manager on PCF.
I have a ASP.NET Web API controller that provides a saveAndNew operation.
This class is derived from System.Web.Http.ApiController as expected.
Application Insights is correctly configured using version 2.1.0 of the SDK and the default settings in ApplicationInsights.config.
If a request to the mentioned operation fails - for example with status code 400 - the request is recorded correctly in App Insights.
The problem is that if the operation SUCCEEDS (status code 200) nothing is recorded in Application Insights.
I've used Fiddler to see if the request is made to the App Insights track service and it is not. So the problem is not in the configuration of Application Insights on the Azure portal.
I can't figure out what is preventing ALL requests to my Web API controllers operations from being recorded.
Can anyone help?
You might want to try removing/commenting out TransferRequestHandler in ApplicationInsights.config file.
GitHub issue "REST API app can have all requests filtered out" here states that: "commenting out the one line in the ApplicationInsights.config caused successful requests to start getting logged. Web API 2 project.

I have an architectural question with signalR
Let's say I have a web app (pure front JS) that use a web api and the web app query an API that do a long task and want to be notified when the task is finished.
So the web api create a fire and forget task, and we use SSE with signalR to notify the web app. It's working. Great, thanks to signalR.
But now, I want the long task to be run in another process, let's say with a msmq based system.
So, the web app query the API, the web api create a message, and the msmq service process the message asynchronously.
Can the msmq service hosted in another process (maybe another machine !) notify the web app that the task is finished ? It can be possible to put the connection id in the message, but the service can be able to send the notification ?
I would use a servicebus, you can then use this library to forward the message directly to the clients.
