Prtg Free - Work Limitations
PRTG (Paessler Router Traffic Grapher) is a popular, all-in-one network monitoring solution. The company offers a “Freeware” edition that is genuinely free to use forever, but it is capped at 100 sensors . While this is generous for small environments, navigating the definition of a “sensor” is critical to understanding the true limitations of the free tier.
