User Load Testing in ThingWorxJava Client TutorialWritten by Tori Firewind, IoT EDC IntroductionAs stated in previous posts, user load testing is a critical component of ensuring a ThingWorx solution is Enterprise-ready. Even a sturdy new feature that seems to function well in development can run into issues once larger loads are thrown into the mix. That's why no piece of code should be considered production-ready until it has undergone not just unit and integration testing (detailed in our Comprehensive DevOps Guide), but also load testing that ensures a positive user experience and an adequately sized server to facilitate the user load.  The EDC has spent quite a few posts detailing the process of setting up an accurate, real-world testing suite using JMeter for ThingWorx. In this piece, we detail an alternative approach that makes use of the Java Spring Boot Framework to call rest requests against the ThingWorx server and simulate the user load. This Java Client tuto

In ThingWorx Analytics, you have the possibility to use an external model for scoring. In this written tutorial, I would like to provide an overview of how you can use a model developed in Python, using the scikit-learn library in ThingWorx Analytics.The provided attachment contains an archive with the following files:iris_data.csv: A dataset for pattern recognition that has a categorical goal. You can click here to read more about this datasetTestRFToPmml.ipynb: A Jupyter notebook file with the source code for the Python model as well as the steps to export it to PMMLRF_Iris.pmml: The PMML file with the model that you can directly upload in Analytics without going through the steps of training the model in PythonThe tutorial assumes you already have some knowledge of ThingWorx and ThingWorx Analytics. Also, if you plan to run the Python code and train the model yourself, you need to have Jupyter notebook installed (I used the one from the Anaconda distribution).For demonstration

Solution Central and Azure Active DirectoryWritten by: Tori Firewind, IoT EDC As we’ve said in a previous post, Solution Central (SC) is a crucial part of any mature dev ops pipeline. In its latest version (3.1.0), it manages custom solutions even more easily due to the SC API. However, this comes with a few requirements that can be a little tricky. One of the more complex configuration pieces for using this new API involves a cloud-hosted Active Directory (AD) application within Azure AD. In order to make use of the new API, your organization’s users must exist on an Azure AD tenant that is separate from the PTC tenant. Most PTC customers are placed on this PTC-owned tenant by default, so additional configuration may be required to set up the AD instance within Azure before the SC API can be used. The type of tenant has to be Azure, of course, as that is what PTC uses: a multi-tenancy Azure infrastructure for all authentication. In this usage, “tenant” is a cloud-hostin

Create an Infotable with a DataShape usingCreateInfoTableFromDataShape(params)3. Using a for loop, iterate through each Json object and add it to the Infotable usingInfoTableName.AddRow(YourRowObjectHere)Example:var params = {    infoTableName: "InfoTable",    dataShapeName : "jsontest"}; var infotabletest = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params); for(var i=0; i<json.rows.length; i++) {   

Introduction to Digital Performance Management (DPM)Written by: Tori Firewind, IoT EDC “Digital Performance Management (DPM) is a closed-loop, problem solving solution that helps manufacturers identify, prioritize, and solve their biggest loss challenges, resulting in reduced cost, increased revenue, and improved service levels.”– DPM Help CenterWhat is DPM?Digital Performance Manager (DPM) is an application which improves factory efficiency across a variety of different areas, namely “the four P’s” of Digital Transformation: products, processes, places, and people. Each performance issue in a factory can be mapped to at least one of these improvement categories in a new strategy for Continuous Improvement (CI) founded by PTC. Figure 1 – Each performance issue in a factory can be mapped to at least one of 4 fundamental improvement categories: products, processes, places, and people. PTC’s new, industry-leading strategy for continuous improvement (CI) in factories is a “best p

ThingWorx community,   As part of a continuous re-evaluation of our third-party software requirements, we regularly add and remove support for versions of operating systems, persistence providers, and web browsers.   On this note, for the ThingWorx release after 9.2 (currently targeted for the end of CY 2021), we are planning to end support for Windows Server 2016. Already five years old, this product has generally been replaced by Windows Server 2019 in common usage.   As per Microsoft’s published lifecycle, this version will be going out of "Mainstream Support" approximately one year after the aforementioned ThingWorx release. PTC will continue to support Windows Server 2019 for the immediate future, and will consider supporting Windows Server 2022 once it becomes Generally Available (GA).   Please let me know if you have any questions or concerns.   Regards,   Walter HaydockThingWorx Product Management

Overview REST stands for representational state transfer and is a software architectural style common in the World Wide Web. Anything with a RESTful interface can be communicated with using standard REST syntax. ThingWorx has such an interface built-in to make viewing and updating Thing properties as well as executing services easy to do independently of the Web UI.   How to Use REST API The ThingWorx REST API is entirely accessible via URL using the following syntax:    (Precision LMS. Getting Started With ThingWorx 5.4 (Part 1 of Introduction to ThingWorx 5.4). PTC University. https://precisionlms.ptc.com/viewer/course/en/21332822/page/21332905.)   The above example shows how to access a service called “GetBlogEntriesWithComments” found on the “ThingWorxTrainingMaintenanceBlog” Thing. Notice that even though this service gets XML formatted data, the method is type “POST” and “GET” will not work in this scenario (Further reading: https://support.ptc.com/appserver/

The DPM User ExperienceWritten by Tori Firewind, IoT EDC Team As discussed in a previous post, DPM is a tool designed to be beneficial at all levels of a company, from the operators monitoring automated data on production events from the factory machines themselves, to the production supervisors who need to establish, task out, and track machine maintenance and improvement measures. DPM also engages the continuous improvement and plant leadership, by providing a standardized way to monitor performance that ultimately rolls up to the executive level. The end users of DPM are therefore diverse both in how they access DPM, and how they make use of its various features. One of the perks to building DPM on top of the ThingWorx Foundation is that many of the webpages (called “mashups”) within ThingWorx are already responsive, and any  which aren’t responsive OOTB can be modified and custom designed for different size viewing screens to ensure that if necessary, end users can a

I recently had a customer who wanted to run services on ThingWorx from Power BI to retrieve existing operational data, and we were a bit stumped on how to pass the API key over in the headers, so I did a bit of Googling and pieced together the solution. It's not quite intuitive on the Power BI side, so I thought it would be helpful to share. If you have any other experience with integrating ThingWorx with Power BI, feel free to add a comment.  Prepare ThingWorxCreate an Application Key that has Run Time execution access to the services you need.Understand the inputs needed for the service you would like.

A license is not required to download and install KEPServerEX V6. After finishing the full install, all features of the KEPServerEX Configuration are available for setup and testing, including the ThingWorx Native Interface. When either a Client application makes a request of a Driver, or a Plug-in becomes activated, then a license check is performed. If a feature is not licensed, a two-hour demo countdown period will begin for that feature. There are System tags that can be monitored in KEPServerEX to determine which features are licensed, which are in a time-limited demo countdown period, and which have expired. To reset the countdown timer for an unlicensed feature, the KEPServerEX Runtime service can be stopped/restarted. See the links and steps below for more information.How do I download and install KEPServerEX?​Monitor licensed, time-limited, and expired features in KEPServerEX:​1.

ThingWorx Performance Monitoring with Grafanaauthored by EDC team member Desheng Xu ( @xudesheng ) Monitoring ThingWorx performance is crucially important, both during the load testing of a newly completed application, and after the deployment of new code in an existing application. Monitoring performance ensures that everything works as expected at the Enterprise level.  This tutorial steps you through configuring and installing a tool  which runs on the same network as the ThingWorx instance. This tool collects data from the Platform and translates it into something visual and easy to understand via Grafana.  tsample is  small and customizable, and it plays a similar role to telegraf. Its focus is on gathering ThingWorx performance metrics. Historically, this tool also supported collecting OS level performance metrics, but this is no longer supported. It is highly recommended to collect OS level performance metrics by using telegraf,
