Is PRTG worth the price?

Good value

PRTG offers a genuinely useful free tier, 100 sensors covering roughly 10 devices is enough for a small office or homelab.

The per-sensor pricing model is both a strength and a trap: each device typically needs 5-10 sensors (CPU, memory, disk, network, services), so a 50-device network easily requires 250-500 sensors. The 30-day trial with unlimited sensors lets you accurately size your needs before committing.

No perpetual licensing exists anymore, it is subscription-only.

Hidden Costs & Gotchas

Sensor count can balloon quickly, each device typically needs 5-10 sensors for meaningful monitoring.

All prices are subscription-only (paid annually). There is no monthly billing option, you commit to a full year upfront.

Remote probes for monitoring distributed locations require additional sensor allocation from your license, there is no separate probe fee, but it eats into your sensor budget.

SNMP, WMI, and flow sensors each count separately against your limit. A single switch with SNMP traffic, bandwidth, and port sensors can consume 10-30 sensors alone.

Email/SMS notifications are included, but advanced alerting integrations (PagerDuty, Slack webhooks) require configuration effort that may need professional services.

Database monitoring, cloud monitoring (AWS/Azure), and advanced flow analysis sensors are included but consume sensors faster than basic ping/SNMP checks.
