All-in-one app monitoring

All your applications' critical stats, at your fingertips: server applications (databases, email, Exchange, …), cloud applications (Azure, AWS, Google Cloud, …), web applications (Zoom, Microsoft 365, …), virtualized applications (Citrix, VMware, Docker Container, …), plus standard Windows applications such as SharePoint, FTP, and Active Directory. If it runs on your network, PRTG can monitor it.

Real-time alerts & notifications

Pick your preferred warning and error thresholds for the various application performance metrics you want to keep an eye on and get notified as soon as an application is at risk of going under or over them, so you can ensure you're using your resources efficiently, avoid network disruption, and leave the office at a reasonable hour.

Monitoring applications: FAQ


1. What is an application?

An application refers to a software program or set of programs designed to perform a specific task or function for end users, businesses, or other software applications. Applications are the tools that allow users to interact with computers and computer systems to accomplish various tasks.

There are various types of applications, including:

  • Desktop applications: These are standalone programs that run on a user's computer. Examples include word processors, spreadsheet software, and graphic design tools.
  • Web applications: These are applications accessed through web browsers over a network. Users interact with them by accessing a specific URL. Examples include email services or online banking.
  • Server applications: These run on servers and provide services or data to other applications or end users. Examples include web servers, database servers, and email servers.
  • Enterprise applications: These are large-scale software solutions used by businesses and organizations to manage their operations. Examples include Enterprise Resource Planning (ERP) systems, Customer Relationship Management (CRM) software, and Supply Chain Management (SCM) systems.
  • Network applications: These are programs that facilitate communication and data exchange between devices on a network. Examples include file transfer protocols (FTP), email protocols (SMTP, IMAP), and network monitoring tools.

2. What is application monitoring?

Application monitoring involves the continuous tracking and analysis of software applications to ensure optimal performance, identify issues, and maintain a positive user experience. Application monitoring tools include monitoring various metrics such as response times, error rates, and resource utilization to detect anomalies or potential problems. This proactive approach allows IT teams to address issues promptly, minimize downtime, and optimize application performance.

3. What is application management?

Application management encompasses a broader set of activities involved in the lifecycle of an application. It includes tasks such as installation, configuration, updating, and overall administration of applications. Application management also involves activities related to user access, security, and ensuring that applications align with business objectives. It focuses on the overall governance and maintenance of applications throughout their lifecycle.

4. What is application performance monitoring (APM)?

APM specifically targets the performance aspects of applications. Application performance monitoring tools and practices are designed to monitor and analyze various performance metrics, such as response times, resource utilization, and error rates. The goal of APM is to identify bottlenecks, inefficiencies, or issues affecting the performance of an application. By closely monitoring these metrics, APM helps organizations optimize application performance, enhance user experience, and troubleshoot performance-related issues.

5. What is PRTG application monitoring?

PRTG is a proprietary software tool that tracks the availability and performance of every application that runs on your network. Available for Windows-based on-premises servers or as a cloud-hosted solution, it's capable of monitoring unlimited web applications, server applications, cloud applications, virtual applications, and more, bringing critical system data together in one simple, intuitive interface you can access from anywhere: at the office, at home, or on the go.

6. What else can PRTG monitor?

PRTG is way more than an application performance or web application monitoring tool: it can keep an eye on your whole IT infrastructure, no matter how complex. We have preconfigured sensors to track a wide range of values, including network traffic, bandwidth, cloud services, availability & uptime, ports, IP addresses, hardware health, network security, and web services. You can also monitor industrial IT and OT environments using OPC UA, MQTT, or Modbus, and create custom integrations with our API.

7. 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.


PRTG the multi-tool

PRTG: The multi-tool for sysadmins

Adapt PRTG individually and dynamically to your needs and rely on a strong API:

  • HTTP API: Access monitoring data and manipulate monitoring objects via HTTP requests
  • Custom sensors: Create your own PRTG sensors for customized monitoring
  • Custom notifications: Create your own notifications and send action triggers to external systems
  • REST Custom sensor: Monitor almost everything that provides data in XML or JSON format
