IoT Tips

If your mashups are feeling cramped and crowded, we’ve got some good news for you. Coming in our next release, ThingWorx will offer truly responsive layouts for your mashups, allowing you to adjust the size of your viewport or present a mashup on a variety of displays—laptop, tablet, phone, etc.—without compromising presentation or responsiveness. This new layout capability is based on Flexbox. Check out this article to learn more.   Here’s a sneak peek of our new layout editor. It’s still in development, but I hope you can start to see how you can use this in your UI development.   Sneak Peek: Responsive Mashup Layout Notice the ability to split the layout into containers. Each of the containers allows you to horizontally or vertically layout, distribute from left or right, align from top or bottom, justify space between widgets, etc. This gives you as the developer ultimate control to define the responsiveness of the mashup.   Like what you see?

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.

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

The natively exposed ThingWorx Platform performance metrics can be extremely valuable to understanding overall platform performance and certain of the core subsystem operations, however as a development platform this doesn't give any visibility into what your built solution is or is not doing.   Here is an amazing little trick that you can use to embed custom performance metrics into your application so that they show up automatically in your Prometheus monitoring system. What you do with these metrics is up to your creativity (with some constraints of course). Imaging a request counter for specific services which may be incredibly important or costly to run, or an exception metric that is incremented each time you catch an exception, or a query result size metric that informs you of how much data is being queried from the database.   Refer to Resources > MetricsServices: GetCounterMetric GetGaugeMetric IncrementCounterMetric DecrementCounterMetric SetGaugeMetric You'll need to give your metric a name - identified by key - and this is meant to be dotted notation* which will then be converted to underscores when the metric is exposed on the OpenMetrics endpoint.  Use sections/domains in the dotted notation to structure your metrics in-line with your application design.   COUNTER type metrics are the most commonly used and relate to things happening through time.  They are an index which will get timestamped as they're collected by Prometheus so that you will be able to look back in time and analyse and investigate what happened when and what the scale or impact was.  After the fact functions and queries will need to be applied to make these metrics most useful (delta over time, increase, rate per second).   Common examples of counter type metrics are: requests, executions, bytes transferred, rows queried, seconds elapsed, execution time.     Resources["MetricServices"].IncrementCounterMetric({ basetype: "LONG", value: 1, key: "__PTC_Reported.integration.mes.requests", aggregate: false });     GAUGE type metrics are point-in-time status of some thing being measured.   Common gauge type metrics are: CPU load/utilization, memory utilization, free disk space, used disk space, busy/active threads.     Resources["MetricServices"].SetGaugeMetric({ basetype: "NUMBER", value: 12, key: "__PTC_Reported.Users.ConnectedOperatorCount", aggregate: true });     Be aware of the aggregate flag, as it will make this custom metric cluster level which can have some unintended consequences.  Normally you always want performance metrics for the specific node as you then see what work is happening where and can confirm that it is being properly distributed within the cluster.  There are some situations however where you might want the cluster aggregation however, like with this concurrently connected operators.   Happy Monitoring!
