Exclude the PRTG data directory ( C:\ProgramData\Paessler\PRTG Network Monitor ) from real-time antivirus scans.
When configuring credentials for SNMP, WMI, or SSH sensors, avoid using Domain Administrator accounts. Instead, create dedicated monitoring service accounts restricted to read-only performance counters.
Stop the PRTG Core Service and manually copy the configuration file ( PRTG Configuration.dat ) and the Logs directory to a secure location.
Not every sensor needs to run every 60 seconds. Move non-critical sensors, such as disk space checks or printer ink levels, to 1-hour or 12-hour intervals. prtg network monitor 21.0.x
The series, released throughout 2021, focused heavily on strengthening core functionality, enhancing security, and introducing specialized sensors for modern infrastructure challenges. This article explores the key features, improvements, and best practices for utilizing the 21.0.x versions of PRTG. 1. Core Improvements in PRTG 21.0.x
In today's digital-first environment, network uptime and performance are critical to business operations. has long been a trusted, all-in-one solution for IT infrastructure monitoring. The 21.0.x release series solidified PRTG's reputation as a robust, scalable tool designed to handle diverse network landscapes—from small business offices to large, complex enterprise environments.
Lookups transform raw numerical values returned by sensors into human-readable states (e.g., mapping an integer status code of 1 to OK , or 2 to Critical ). In 21.0.x, lookups are defined using structured XML files placed in the \lookups\custom directory. This allows administrators to customize color-coded alerting states for specific enterprise hardware platforms. Stop the PRTG Core Service and manually copy
A dedicated cross-platform application (Windows, macOS, Linux) that allows administrators to connect to multiple PRTG instances simultaneously and receive native desktop notifications.
While the web interface remains the go-to for many, the 21.0.x era solidified the . It provides a native experience for Windows and macOS, allowing admins to manage multiple PRTG cores from a single pane of glass without the overhead of a heavy browser tab. 3. Native Sensor Refinement
Exclude the PRTG data directory ( C:\ProgramData\Paessler\PRTG Network Monitor ) from real-time antivirus scanning to prevent file locking and database corruption. The series, released throughout 2021, focused heavily on
The core strength of the 21.0.x version lies in its . Instead of requiring multiple tools for different components (servers, cloud, traffic), PRTG provides a unified interface where all data is gathered by "sensors." Key Components:
: Runs as a Windows-based application that automatically discovers devices on your network to streamline setup.
