Product Details

What PRTG monitors

PRTG is sensor-driven: each sensor polls a single metric (CPU, ping, traffic flow, HTTP response, SNMP OID). Combined sensors let teams track servers, VMs, storage, network interfaces, routers, firewalls, cloud services and even environmental IoT sensors. It supports NetFlow/sFlow/IPFIX, packet sniffing, WMI, SNMP and custom scripts so you can monitor both infrastructure and application-level performance in one place.

Deployment & licensing

Install PRTG on Windows servers for on-premises monitoring or subscribe to PRTG Hosted Monitor for a cloud option. Licensing is sensor-based: choose a sensor bundle that fits your environment and scale up as needed. Paessler offers free trials for evaluation, maintenance/subscription renewals for updates, and volume pricing for larger deployments.

Support & integrations

Paessler provides documentation, a knowledge base, community forums and commercial support plans. PRTG exposes REST APIs and supports notifications via e-mail, SMS gateways, push apps and third-party integrations. Native mobile apps and customizable maps/dashboards help operations teams visualize status and react quickly to incidents across distributed infrastructure.
