My goal is to include VR specific events in an ETL capture file to be able to analyze some performance issues.
There are custom providers for Oculus and SteamVR runtimes, but I could not find any documentation about ETW events produced by WMR runtime.
I could not identify any obvious candidate in the output from logman query providers.
There is a provider that might be what you're after:
ProviderGUID: 60d6e217-d25b-504f-83d5-c2deb6a854e5
ProviderName: Microsoft.Windows.Holographic.MixedRealityMode
ProviderGroupGUID: 4f50731a-89cf-4782-b3e0-dce8c90476ba
AssociatedFilenames: ["spectrum.exe"]
I have no idea where the list came from.
For performance debugging WMR headsets apps, it is recommended you use the new Tools in Windows Device Portal. And refer to this broader discussion on performance help: Understanding performance for mixed reality
Currently, the ETW provider GUID of WMR runtime doesn't yet public on our official documentation. If you already have a specific performance issue on WMR, it is recommended to open a support ticket through this link: http://aka.ms/mrsupport for a one-to-one support service. We will also forward this one about the ETW provider to the product team to see if it’s feasible to clarify that in the official docs.

Hello we are trying to determine the best or appropriate architecture for tracking events as they occur between microservices. We know loose coupling begins this process for good microservice design. The use case is to literally query how a company's automation is taking place in real time or historically. There are many products such as Kafka, Solace, MassTransit (mediator, riders, message queues, sagas, routing slips).
Just basic advise at this point. We have to implement saga and routing slip patterns to satisfy our business model.
I would recommend starting by taking a look at the Open Telemetry (OTel). It's a CNCF project, so not tied to specific product, and their goal is to provide a level of observability across your architecture, including the ability of tracing across distributed apps (whether they are sync or async).
I will warn that there is currently a SIG focusing on defining the messaging semantics so this isn't a fully baked solution at this point. You can find more info on that SIG here. They are working to replace the existing experimental messaging semantic conventions with a stable document as things go GA.
That said, you'd probably want to start with instrumenting your apps/microservices and OTel has a number of auto-instrumentation libraries for different APIs & languages in various OTel repos. For example, the repo for the Java agent with a number of auto-instrumentation implementations (including JMS) can be found here: https://github.com/open-telemetry/opentelemetry-java-instrumentation. The idea of the auto-instrumentation is that it doesn't require app code changes so as things evolve it should be easy for you to evolve with it, which is obviously ideal since the messaging semantics are still in work.
Agree with the Open Telemetry comment above. As far as what is currently used most widely (by any tech or framework involved) in microservices is its predecessor Open Tracing (Open Telemetry is backward compatible to Open Tracing and/as OpenTracing is also CNCF). If interested we have created a microservices workshop that uses tracing across both Rest and messaging (specifically JMS) so you can see working examples. You can view these traces in Jaeger UI and such. In the same workshop we show "unified observability" where we show metrics, logging, and tracing all within the same Grafana console. This is really handy as you can, eg, see metrics and/or get a metrics alarm/alert, drill down to its corresponding log entries, and then click/drill down directly from a log entry to its trace (and vice-versa). Full disclosure, I am from Oracle, and so we also show the ability to trace from the OpenTracing/Kubernetes layer, down into the database thus showing the "3 pillars of observability" across both app and data tiers ...but you don't need the database to do any of the other tracing, etc. shown. The workshop is here:https://apexapps.oracle.com/pls/apex/dbpm/r/livelabs/view-workshop?p180_id=637 and the src is here: https://github.com/oracle/microservices-datadriven . I'm definitely interested if you'd like to see add anything added or have any questions, etc. We'll be adding more OpenTelemetry to it as its adoption grows.
Is it possible to scale Axon Framework without Axon Server Enterprise? I'm interested in creating a prototype CQRS app with Axon, but the final, deployable system has to be be free from licensing fees. If Axon Framework can't be scaled to half a dozen nodes using free software, then I should probably look elsewhere.
If Axon Framework turn out not to be a good choice for the system, what would you recommend? Would building something around Apache Pulsar be a sensible alternative?
I think I have good news for you then.
You can utilize Axon Framework perfectly fine without Axon Server Enterprise.
Firstly, you can use the Axon Server Standard edition, which is completely free and you can check out the code too if you want.
If you prefer to get infrastructure back in your own hands, you can also select different approaches to distributing the CommandBus and the EventBus/EventStore.
For the CommandBus the framework provides the DistributedCommandBus for which two implementation are in place, being:
JGroups
Spring Cloud
I'd argue option 2 is the most ideal for distributing your commands, as it gives you the freedom to choose whichever Spring Cloud Discovery Service implementation you desire. That should give you the handles to work "free of licenses" in that area.
For distributing your Events, you can broadly look at two approaches:
Share the database, aka your EventStore, among all instances
Use a event message bus to distribute your event messages
If you want instances of your nodes to be able to Event Source the Command Model, you are inclined to use option 1. This is required as Axon Framework requires a dedicated EventStore to be able to source the Command Models from history.
When you just want to connect other applications to your Event Stream, option 2 would be a good fit. Again, the framework has two options in this area:
AMQP
Kafka
The only thing I'd like to point out on this part additionally is that the Kafka extension is still in a release candidate state. It is being worked on actively at the moment though.
All these extensions and their options should be clearly stated in the Reference Guide, so I'd definitely check this documentation out if you are gonna start an application.
There is a sole thing you cannot distribute though, which is the QueryBus.
There is an outstanding issue to resolve this, for which someone put the effort in to provide a PR.
After seeing how Axon Server Standard edition does it though, he intentionally closed the PR (with the following comment) as it didn't seem feasible to him to maintain such a tool at this stage.
So, can you use Axon Framework without Axon Server Enterprise?
Well, I think you can. :-)
Mind you though, although you'd be winning on not having a license fee if you don't use Axon Server Enterprise, it doesn't mean your production is gonna be free.
You'd be introducing back quite some infrastructure set up and production time to get this going.
Hope this gives you plenty of feedback #ahoffer!
I'm interested in deploying an enterprise service bus on a fault tolerant system with a variety of use cases that include tracking network traffic and analyzing social media data. I'd prefer to use a streaming application, but open to the idea of micro-batching. The solution will need to be able to take imports and exports from a variety of sources (bus).
I have been researching various types of stream-processing software platforms here:
https://thenewstack.io/apache-streaming-projects-exploratory-guide/
But I've been struggling with the fact that many (all) of these projects are open source and I don't like the large implementation risk.
I have found Apache Kafka attractive because of the Confluent Platform built on-top, but I can't seem to find anything similar to Confluent out there and want to know if there are any direct competitors built on top of another Apache project. Or an entirely private solution.
Any help would be appreciated! Thanks in advance!
I have developed a serious game(learning game) in Unity. I would like the game to be TinCan compliant. Can somebody tell me about the processes involved in making it TinCan compliant?
Tin Can compliancy doesn't really have a specific technical meaning, in so far as it can be tested objectively. Having said that, if your content tracks its experience (learning) data in a Learning Record Store (LRS), specifically a "conformant" LRS (see test suites or ask your vendor) then that content would generally be considered "Tin Can Compliant" because it is up to the LRS to enforce the requirements in the specification itself.
We (Rustici Software) have published a number of open source libraries that can be used to assist developers in communicating with an LRS in a conformant way, one or more of them can be used in a Unity application, and the list can be found at http://experienceapi.com/libraries/. There are several LRSs that are generally considered to be spec conformant, and our Cloud based product provides a free for testing LRS.
Here is a simple Unity game example sending a xAPI statement
https://github.com/HT2-Labs/unity-xapi
It is sending one xAPI statement from Start() at game initialization.
To make this example work:
git clone locally Unity example from github
add it to your local Unity hub
there will be warning about Unity old version of the example, select whatever Unity version you use and confirm version upgrade
open TinCanTest.cs in Visual Studio, change
string endpoint = "https://ORG_NAME.learninglocker.net/data/xAPI";
string user = "KEY";
string password = "SECRET";
to credentials of your LRS and try running the game.
A similar stackoverflow question.
Me and my team were tasked to integrate our application with Alcatel Genesys call center, but we don't have access to a proper instalation nor equipment (like, for instance, phones).
Is there some kind of software I can use to simulate such environment to test our application? And where should I begin researching how to do this integration?
(PS: I posted this same question on https://serverfault.com/questions/308381 - I didn't exactly know which of the sites this really belongs to).
Doesn't look like there is a public one. You would probably have to go through one of their product managers.
The Genesys Platform SDK documentation appears to be public though:
http://docs.genesyslab.com/Documentation/PSDK
The good news - you do not need phones to test integration with Genesys. The bad news is that integrating requires quite a lot of components and is quite complicated so there is no simulator or mock interface you could use. One of the best ways would be to get in contact with Genesys tech support who are usually quite helpful or pre-sales and ask them about access to a virtual demo image you could use for integration.
Also a great resource of information is their newly designed doc site:
http://docs.genesys.com/Documentation/OS
Also Alcatel has sold Genesys a while ago and they're independent now, just in case ;-)
Actually there is. Genesys Simulator Toolkit. It will enable to emulate an Avaya PBX or a Simple TDM scenario. Last version also includes as Genesys SIP Server emultaor.
You won't care too much about the PBX on the other side for basic integrations, your goal is to learn the SDK and the TEvents (TLib). You can achieve this with the Emulator. You need to ask it to a Genesys representative.
