Paessler PRTG

Sensor-based all-in-one monitoring with published subscription prices

Overview

PRTG is developed by Paessler GmbH of Nuremberg, Germany[2]. It monitors systems, devices, traffic and applications through “sensors”, each of which measures one value such as an interface’s bandwidth, a device’s CPU load or a URL’s response time; custom thresholds trigger alerts, and the HTTP API and custom sensors extend coverage[2]. SNMP is the main protocol for network devices, and flow-based traffic analysis is available[2].

The product family includes PRTG Network Monitor for self-hosted use, PRTG Enterprise Monitor for large environments and PRTG Hosted Monitor as a SaaS option[2]. Paessler recommends Enterprise Monitor for more than 1,000 devices[1].

PRTG’s licensing by sensor count is straightforward to understand, with subscriptions from PRTG 500 at US$200 per month billed annually (about 50 devices) to PRTG 10000 at US$1,642 per month (about 1,000 devices)[1]. A Freeware Edition covers up to 100 sensors (about 10 devices), and a 30-day trial has no sensor limits[1]. Because each monitored value consumes a sensor, detailed monitoring of many interfaces can exhaust a licence faster than device counts suggest. Enterprise Monitor pricing is not published[1].
