Is there a NATS Web UI tool to monitor messages? - nats.io

Is there any tool available to monitor the actual messages published through a NATS queue? For a presentation I need to display the messages displayed through a microservice architecture and it would be nice to do that via an existing solution in stead of writing one on my own.
I now there is Natsboard (https://github.com/devfacet/natsboard) but it doesn't allow to display the existing messages.
Would be great to get some hint for that by you guys.
Regards
Patrick

Have a look at the nats-streaming-console: https://github.com/KualiCo/nats-streaming-console

Bidirectional communication between R and Microsoft Teams - any ideas?

I am working on a small project trying to control some steps of a workflow in a web application using MS teams. My idea is to use R as an intermediate step between the application (which has a number of API endpoints I can call from R) and Microsoft Teams chats (or channels). Users would then use a set of keywords in the chat to lead to an action in the application. For example they might use "publish ABC-123" in a specific chat and this would lead to the application publishing document ABC-123 somewhere via R which would orchestrate everything.
I have a couple of ideas but there are drawbacks:
I thought originally about using microsoft365r. We have an app registered in Microsoft 365 which would allow us to monitor a specific chat for messages that trigger actions in R. The problem with this approach is that we would need to have the R code running and checking MS Teams every couple of minutes. It is certainly doable, but not very elegant.
Another option could be setting up a plumber API and an outgoing webhook in MS Teams. This seems like the ideal way to do it, but webhooks in MS Teams require https and as far as I understand this is not straightforward to implement in plumber.
I would appreciate any ideas on how to do this. I know I am not very specific, but mostly looking for high level pointers of what I could look at. Many thanks!
You actually have a bunch of options for this:
Create a bot directly in code, e.g. per https://learn.microsoft.com/en-us/microsoftteams/platform/bots/what-are-bots . There's a bit of a learning curve of course, and it depends on whether you have development skills outside of r, e.g. python, .net, whatever. The bot would then call your code as needed.
Create a no-code bot using Power Virtual Agents. This is the equivalent, for bots, of Power Apps or Power Automate, if you're familiar with those.
Create a workflow, either in Power Automate or Azure Logic Apps, that can listen for and respond to messages. This is kind of similar to a bot, but with finer scope (and therefore less capability). If you want it to call out to your app, e.g. to an endpoint, you'd need a Premium Connecter for Power Automate, or you can use an Azure Logic App directly (uses the same engine, but the pricing model is different for these and Power Automate is a little easier to work with.
Outgoing webhook - you can implement these as standalone, but actually from your use case it sounds like a bot would be better anyway, and it's kind of what you need to build to make this kind of webhook work properly anyway.

Extending Apache Kafka to web and mobile apps

I am exploring Apache Kafka for building an application and it really suits our needs. However, as part of our application, we also need to push data streams and notifications to user’s apps and web dashboards. AFAIK Kafka clients do not support JavaScript so integration with web dashboards seems to be a challenge.
I want to know
What would be the best way to extend messages received in Kafka topic to web dashboards, assuming thousands of logged-in users. ( web socket is no option here)
What are the best available Kafka clients for iOS and Android.
Also, I am wondering that generally speaking, what would be the best way to fan-out messages coming in from a Kafka topic to thousands of end devices ( like websites, phones, IoT terminals, etc.). Any general or tool-specific suggestion would be awesome.

kafka-connect is a good use-case.
Please check the details here : https://www.npmjs.com/package/kafka-connect.
The other option is to have a micro-service to produce and consume. It is a good option if you later want to do additional operations before publish or after publishing.

Is there any way to get button answer without interactive message?

We're implementing a slackbot internally in our company.
Because we cannot open a local server on internet, we want to bypass interactive message system.
Is there any way to do so ? A custom event for example ?
Thanks,
Yohann.
No, that is not possible.
And frankly, you can not use much of Slack's functionality without exposing your app to the Internet, so that Slack can interact with it.
But there are ways to expose your app to the Internet, without compromising the security of your company network. One way is to use a secure tunnel to your "localhost". A service provided by companies like ngrok.

ASP.NET webhooks : receive webhook into aplication

I have an application which has a feature where user can post message into a channel like for internal communication.
I am thinking to implement webhooks where we can get third parties data into channel.it may an alert from server or anything similar.
is this possible using ASP.NET webhook custom packages?
if yes, any idea from where I can start or for this moment it only support /receive data into the supported parties?
Thanks
yes, that's absolutely possible. A big part of ASP.NET WebHooks is that you can enable your own WebHook support (under the Custom namespace). There are several samples showing how to do this and you can also see this blog [1]
Hope this helps!

Looking for guidance on WF4

We have a rather large document routing framework that's currently implemented in SharePoint (with a large set of cumbersome SP workflows), and it's running into the edge of what SP can do easily. It's slated for a rewrite into .NET
I've spent the past week or so reading and watching WF4 discussions and demonstrations to get an idea of WF4, because I think it's the right solution. I'm having difficulty envisioning how the system will be configured, though, so I need guidance on a few points from people with experience:
Let's say I have an approval that has to be made on a document. When the wf starts, it'll decide who should approve, and send that person an email notification. Inside the notification, the user would have an option to load an ASP.NET page to approve or reject. The workflow would then have to be resumed from the send email step. If I'm planning on running this as a WCF WF Service, how do I get back into the correct instance of the paused service? (considering I've configured AppFabric and persistence) I somewhat understand the idea of a correlation handle, but don't think it's meant for this case.
Logging and auditing will be key for this system. I see the AppFabric makes event logs of this data, but I haven't cracked the underlying database--is it simple to use for reporting, or should I create custom logging activities to put around my actions? From experience, which would you suggest?
Thanks for any guidance you can provide. I'm happy to give further examples if necessary.
To send messages to a specific workflow instance you need to set up message correlation between your different Receive activities. In order to do that you need some unique value as part of your message data.
The Appfabric logging works well but if you want to create custom a custom logging solution you don't need to add activities to your workflow. Instead you create a custom TrackingParticipant to do the work for you. How you store the data is then up to you.
Your scenario is very similar to the one I used for the Introduction to Workflow Services Hands On Lab in the Visual Studio 2010 Training Kit. I suggest you take a look at the hands on lab or the Windows Server AppFabric / Workflow Services Demo - Contoso HR sample code.
