5 reasons why experts monitor industrial IT with PRTG

IT/OT convergence, Industry 4.0, and increased digitalization all shape the way the production floor connects and interacts with IT. This interconnectivity makes it crucial to have a central overview
of your entire infrastructure.


  • Get out-of-the-box support for common industrial standards & protocols (OPC UA, MQTT, Modbus, and more)
  • Collect data about the factory floor and IIoT from industrial gateways
  • Keep an eye on industrial ethernet devices in your OT environment
  • Visualize your environment in dashboards that bring together IT, OT, and IIoT elements
  • Extend the functionality of common industry solutions with comprehensive monitoring

IT/OT convergence makes industrial IT monitoring with a single solution essential








Traditionally, classic IT networks were monitored separately from OT components, if the OT was monitored at all. Because of the increased digitalization and connectivity of OT environments, however, keeping an eye on both IT and OT becomes more and more important. So why should you monitor industrial IT?



Get the right data to the right teams

Previously segregated teams now rely on each other. For example: IT teams are responsible for ensuring that the data generated by machines on the factory floor makes its way to the cloud, while industrial engineers or managers might need access to that data to make decisions regarding the production line or to implement predictive maintenance strategies. All teams need to work from the same data, but they need different views of it.

Prevent issues with root cause analysis

Because data flows through several systems, all gears need to work flawlessly together: if one doesn’t work, other processes will be impacted, too. If a failure occurs, a simple alert to troubleshoot the issue is not enough. Teams need to understand the root cause of a problem to prevent it from happening in the future. But to find the root cause, teams need to look across systems and interfaces.

Keep data flowing without interruption

Digitalization has made it vital to be able to generate and analyze insights using data from all parts of the enterprise. Data created on the factory floor must be aggregated and sent to upstream on-premises or cloud systems for processing. Because this data travels across OT and IT networks, it’s essential to monitor that it flows correctly through various interfaces and touchpoints in the infrastructure.

The integration of technology into industrial processes can lead to cost savings, improved product quality, increased safety, reduced downtime, and better utilization of resources.

2. What is the role of monitoring industrial IT?

Industrial IT monitoring plays a crucial role in maintaining and optimizing the performance of industrial processes, systems, and equipment. It involves the continuous collection, analysis, and visualization of data from various sources within an industrial environment.

The primary purpose of industrial IT monitoring is to ensure that operations are running smoothly, identify potential issues or anomalies, and enable timely intervention to prevent disruptions.

Industrial IT monitoring is also a proactive approach to managing industrial processes and equipment. It enables companies to enhance efficiency, reduce downtime, increase product quality, and maintain a competitive edge by leveraging real-time data and insights for continuous improvement.

3. What benefits does the convergence of IT and OT provide for the manufacturing sector?

IT/OT convergence, referring to the integration of Information Technology (IT) and Operational Technology (OT) systems, offers several compelling benefits for organizations in various industries. Here are some reasons why you should consider IT/OT convergence:

  • Improved visibility and decision-making: Converging IT and OT systems provides a unified view of both business operations and industrial processes. This comprehensive visibility allows for better-informed decision-making, as you can understand how IT data (like business metrics) and OT data (like production metrics) interact and impact each other.
  • Efficient data utilization: IT systems are adept at handling and analyzing large volumes of data, while OT systems generate vast amounts of operational data. Convergence enables the efficient utilization of data from both domains, leading to insights that were previously hidden when the systems were separate.
  • Enhanced efficiency and productivity: When IT and OT systems are integrated, processes can be streamlined and automated more effectively. This leads to increased operational efficiency, reduced manual intervention, and ultimately higher productivity.
  • Predictive maintenance: Converged systems enable the implementation of predictive maintenance strategies. By analyzing data from IT and OT sources, you can predict equipment failures and schedule maintenance activities before issues cause downtime or disruptions.
  • Cost savings: By optimizing operations through data-driven decisions, reducing downtime, and minimizing equipment failures, IT/OT convergence can lead to significant cost savings in terms of maintenance, energy consumption, and resource utilization.
  • Security improvements: While convergence increases connectivity, it also highlights the importance of robust cybersecurity measures. By addressing security concerns across both IT and OT domains, you can enhance overall system resilience and reduce vulnerabilities.
  • Adaptation to industry trends: Modern industries are becoming more digitalized and interconnected. IT/OT convergence positions your organization to adapt to these industry trends effectively and remain competitive.

4. How can an industrial IT monitoring tool help me?

An industrial IT monitoring tool like Paessler PRTG can provide you with a range of benefits:

  • Real-time visibility: An industrial IT monitoring tool allows you to monitor your industrial processes and equipment in real time. You can visualize critical data such as temperatures, pressures, flow rates, and other process variables, giving you an instant overview of your operations.
  • Anomaly detection: The monitoring tool can automatically detect anomalies or deviations from normal operating conditions. This early detection helps you identify potential issues before they escalate into larger problems, allowing for timely intervention and maintenance.
  • Data analytics: Industrial IT monitoring tools often include analytics capabilities that allow you to perform in-depth analysis of your data. You can identify patterns, correlations, and trends that can guide decision-making for process improvements and operational strategies.
  • Remote monitoring: Many monitoring tools offer remote access, enabling you to monitor your operations from anywhere. This is particularly useful for overseeing multiple sites or when you need to make quick decisions while off-site.
  • Alerts and notifications: The tool can send alerts and notifications when predefined thresholds are exceeded or anomalies are detected. This ensures that you're promptly informed about critical situations that require attention.
  • Regulatory compliance: For industries with regulatory requirements, monitoring tools can help you collect and document the necessary data to meet compliance standards. This simplifies reporting and auditing processes.
  • Data visualization: Monitoring tools often include customizable dashboards and visualizations that allow you to present data in a clear and understandable format. Visualizations make it easier to track key performance indicators and make informed decisions.
  • Improved decision-making: Access to real-time and historical data empowers you to make informed decisions based on accurate information. This can lead to better strategic planning and operational execution.
  • Integration with other systems: Many monitoring tools can integrate with other software systems, such as ERP (Enterprise Resource Planning) or CMMS (Computerized Maintenance Management System), creating a unified ecosystem that enhances overall operational efficiency.

5. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
