IoT Tips

Disclaimer: Please note that, while the ThingWorx Git Backup Extension is a very useful tool, it is not a PTC product, nor is it supported by PTC.   Hi ThingWorx users,   Trying to manage your ThingWorx application artifacts in a CI process? Wondering who changed that line of code in your Thing Service? Trying to see what your Mashup looked like last release? Time to Git excited! Introducing the Git Backup Extension, an open-source tool available here to offer a stronger integration with the Git source repository. This Git feature can push or pull code and artifacts (like entities, data exports or extension dependencies) to your Git repository.   Here are some highlights of how this works within ThingWorx:   First, configure your Git repo to work with ThingWorx by creating a Git Backup Thing. Then, simply open your new Thing, navigate to the Configuration editor and enter information like your Git URL, your Git username and password, your repo and branch names, etc. See example below. Configuring your Git repoWith this configuration in place, you can now use the Home Mashup of this new Git thing to browse the repository and pull down contents to your local ThingWorx instance. For new projects, you can also push new entities to the repo as you work on your application.   As you and your team are working, you’ll want to see the differences of the files you are editing and working on collaboratively. The Git extension feature makes this easy. Just like you can see diffs clearly delineated for a file with your Git client, you can see the same with this Git integration in ThingWorx. Similar to the git status command, the Git ThingWorx extension will show you the list of files you have changed that are available to push, as well as their diffs. See an example below. Checking the Git status While working, if you want to switch branches or pull down a new project, you can check out a specific version and see all commits available on that branch (see below). Checking out a specific commit Want to learn more or try it for yourself? Find the open-source Git Backup Extension here and check out the Git Backup Extension User Guide for guidance.   Stay connected, Kaya   P.S. What do you think? Comment your thoughts below!

Meet Neal. When Neal joined PTC five years ago, he immediately hit the ground running on IoT initiatives, working in multiple areas ranging from pre-sales to partner relations. Today, he is a Worldwide ThingWorx Center of Excellence Principal Lead at PTC, and his biggest focus is supporting the go-to-market for the Microsoft partnership.   I sat down with Neal recently to hear the details on exactly how Azure and ThingWorx can be used to develop world-class IIoT applications.   Kaya: Can you explain how Azure and ThingWorx work together? Neal: Yes, so Azure provides the cloud infrastructure that our customers need in order to deploy ThingWorx.   By having Azure as our preferred cloud platform, we’re able to specialize our R&D efforts into utilizing functionality that is available in Azure, rather than having to reinvent the wheel ourselves for each cloud platform in the attempt to remain cloud-agnostic. By leveraging a single, already quite powerful, cloud platform through Azure, we’re able to maximize our development efforts.   Kaya: What was the major problem that led to us investigating cloud options? Neal: There were two issues that our users had. The first was we often had complicated installs and setup procedures because we were genericizing the whole process, so the initial setup and run was complicated and expensive. For example, we were requiring them to setup additional VMs and components, and we were giving them generic instructions because we were being very agnostic, when they had already chosen outside of us to use one of the cloud platforms. We knew our customers wanted to move fast, so we had to make it easier and faster for them to see results.   The other issue we ran into with customers was the confusion in the offerings. For ThingWorx, ingest is just one aspect of IoT. ThingWorx is particularly strong in areas like enabling mixed reality and augmented reality as well as application enablement. And, while we also have the ability to perform ingest capabilities, Microsoft is especially powerful when it comes to ingest capabilities and security. We decided that the smartest solution was to leverage Microsoft’s expertise in data ingestion to make ThingWorx even more powerful; so, we made the Azure IoT Hub Connector. By partnering with Microsoft, we have joint architecture where you can see how Microsoft provides key features and ThingWorx will run on top of those features and get you faster to the market to develop the application.   Below is an example of a high-availability deployment of ThingWorx on Azure that utilizes ThingWorx Azure IoT Connectors to access an Azure IoT Hub.  High-Availability Deployment of ThingWorx on Azure Kaya: Why did we partner with Azure? What specific benefits does Azure offer over other cloud services providers? Neal: When we started to look at what our customers were using for cloud services, we noticed that a lot were using Microsoft. When we join forces with Microsoft, we have a much more wholistic offering around digital transformation. With the partnership, PTC and Microsoft are able to leverage each partner’s respective strengths to provide even more powerful IIoT solutions. You have Windchill and Microsoft’s business application strategies; you have Vuforia and Microsoft’s mixed reality and augmented reality strategies; and, you have ThingWorx on the Microsoft Azure cloud. Overall, you have a much more complete and powerful offering together.   Kaya: What is your favorite aspect about working at PTC? Neal: The growth. There’s been a lot of changes over the last five years that I’ve been here. PTC has been able to leverage its strengths and long-time experience in the CAD and PLM markets to enter and ultimately become a leader in the IIoT market, according to reports by research firms like Gartner and Forrester. In short, the growing IIoT market and PTC’s leadership in the industry.   Note to Readers: You’ve likely heard about our major strategic partnership with Microsoft to leverage our respective IIoT and cloud technologies to optimize the creation, deployment, management and overall use of your IIoT applications. If you haven’t heard about the partnership, check out the press release here.

Just like the perfect sandwich, we know that you have specific preferences and requirements for your ThingWorx deployment. Whether you like to keep things simple with a classic grilled cheese or you like to spice things up with a more elaborate chipotle mayo BLT, we’ve got you covered. Our ThingWorx Deployment Architecture Guide explains what you’ll need to deploy ThingWorx in three different scenarios: production, enterprise and high-availability (pictured below).   Deployment Architecture for ThingWorx on Azure in High-Availability We’ve recently published Version 1.1 of the ThingWorx Deployment Architecture Guide. In it, you can find updated deployment architecture diagrams to more distinctly show the data and application layers within a ThingWorx environment. Our team has also added a new section on what you’ll need to deploy ThingWorx on Microsoft Azure, PTC’s preferred cloud platform.   Check it out here or in the attachment section on the right.   Stay connected, Kaya

Hi, ThingWorx users! We’re excited to share that we have partnered with InfluxData to make time series analysis in ThingWorx even easier. InfluxDB is a database by InfluxData that is “built specifically for metrics and events that empower developers to build next-generation IIoT, analytics and monitoring applications.”   Why InfluxData?  Today, application developers expect robust querying capabilities, fast response time, easy ways of aggregating and pivoting on data and leveraging results for reporting and visualization. IT and devops administrators also expect cost-effective storage and easy ways of aging data through archiving and the ability to keep large amounts of historical data to satisfy analysis requirements.   That’s why we’ve partnered with InfluxData to make it easier for developers to store, analyze and act on IIoT data in real-time. With InfluxData, developers can build connected IIoT applications more quickly while still incorporating the following capabilities: monitoring real-time alerting predictive maintenance streaming data anomaly and event detection visual and report-based analysis   We considered a few technologies for the purpose of improving ThingWorx time series analysis. Here are a few reasons we chose InfluxData: high compression of data ~45x ability to handle millions of writes per second* ability to read around thousands of rows in milliseconds* supports the standard time series functions of sampling, interpolation, time bucketing, aggregation, selector, transformation, predictor, etc.  * Query and write times will vary based on an individual ThingWorx application’s implementation with Influx. For example, as the number of concurrent reads increases, the query speed decreases. With the upcoming 8.4 release, the ThingWorx Sizing Guide will be updated to reflect representative performance for ThingWorx developers.   In addition to improved query capability, ThingWorx time series with Influx can now use less memory and CPU, giving your platform servers a bit of a break.   To start strategizing on how InfluxData can help you in your ThingWorx journey, here is a sneak preview of what it will look like:   New Features The new ThingWorx Influx Persistence Provider will make query services like ValueStream Thing QueryPropertyHistory, Stream Thing QueryStreamData and QueryStreamEntries even better. Simply create a new instance of the persistence provider, configure it to use your InfluxDB instance, create a new value stream (or stream) from the new persistence provider, and you’ll be writing, reading and analyzing your time series data like never before.   We’re also introducing a new enhancement to improve InfoTable support with time series data, including providing the ability to use a driver property. The driver property can be specified with the QueryPropertyHistoryWithDriverProperty service for time alignment and filling backward/forward in your stream queries.   Let’s walk through a driver property example where you have the properties of temperature, speed and battery level. Timestamp Temperature Speed Battery Level 1480589076592000000 80.003 5012 79 1480589077537000000 80.010 5011 79 1480589077550000000 80.010 5009 79 1480589077562000000 80.030 5011 78   Let’s say temperature is the key driver for your analysis. In other words, you are not concerned if speed or battery level changes—you only care about when temperature changes. We can specify temperature to be the driver property for that particular time and only return stream values for temperature, speed and battery level when temperature changes. If speed or battery level changes (but temperature does not change), the rows associated with those changes would not be included in the results set because neither speed nor battery level is a driver property. See chart below.  Timestamp Temperature (driver) Speed Battery Level 1480589076592000000 80.003 5012 79 1480589077537000000 80.010 5011 79 1480589077562000000 80.030 5011 78  Note that only three of the four rows are returned above because one entry in the original table did not have a change in temperature.    Stay Tuned Look out for these time series improvements and InfluxData integration in our upcoming 8.4 release.
