This document will give an in-depth look at how PRTG works, its features, and the company behind the software.

How PRTG Works

PRTG Network Monitor utilizes a combination of sensors, probes, and a central server to collect and analyze data from various network devices and applications. Here’s an overview of the components:

  • Sensors: A sensor is the core monitoring unit in PRTG. Each sensor is responsible for gathering specific data from a single aspect of a network device or service. PRTG offers over 250 pre-built sensor types to monitor various network components such as bandwidth usage, server performance, and application status.
  • Probes: Probes are responsible for distributing the monitoring load. They collect data from sensors and transmit it to the PRTG core server. PRTG comes with a default local probe that runs on the same machine as the core server; however, additional remote probes can be deployed to monitor devices in separate locations or networks.
  • Core Server: The core server is the central component of PRTG. It processes the data received from the probes, generates alerts, and stores monitoring data in the database. The server also hosts the PRTG web interface, which allows administrators to manage and visualize the monitoring data.

Key Features

PRTG Network Monitor offers numerous features that enable IT administrators to efficiently monitor and manage their networks:

  1. Auto-Discovery: PRTG automatically discovers and classifies network devices, allowing for a quick and easy setup.
  2. Customizable Dashboards: Users can create personalized dashboards with customizable maps and graphs to visualize monitoring data.
  3. Alerting: PRTG sends notifications via email, SMS, or push notifications when specific thresholds are breached, enabling IT administrators to address issues before they escalate.
  4. Reporting: PRTG generates detailed reports on network performance, uptime, and other metrics, which can be shared with stakeholders or used to optimize network performance.
  5. Scalability: PRTG can scale from small networks to large, multi-site environments thanks to its flexible architecture and probe system.
  6. Application Monitoring: PRTG supports monitoring of various applications and services, such as web servers, email servers, and database servers.
  7. Failover Cluster: PRTG’s failover clustering feature ensures continuous monitoring even if the primary server goes offline.
