    什么才算一个sensor

    What counts as a sensor?

    The licensing options are based on the number of sensors. Each of the following items counts as one sensor:

    • Monitoring traffic/bandwidth on one port of any device via SNMP (e.g. switch, firewall, server) using the MIB2 standard
    • Monitoring errors/min, unicast packets/s, non-unicast packets/s on one port of a device via SNMP using the MIB2 standard
    • Monitoring one other system parameter via SNMP (e.g. CPU, diskspace etc.) that is accessible via one OID value
    • Monitoring traffic going through one local network card (NIC) via Packet Sniffing. If you use filtering then each set of filters counts as one sensor.
    • Monitoring of one stream of data traffic via xFlow (NetFlow, sFlow) Monitoring. If you use filtering then each filterset counts as one sensor.

    The number of actual hardware devices is not taken into account at all, only the number of sensors. For the “unlimited licenses” the number of sensors that can be monitored is not programmatically limited by the software itself, but may be limited by your software, hardware and network.

    What is a Probe?

    Each license of PRTG includes a certain number of so called probes that perform the monitoring:

    • One (local) probe is installed with the core server. It performs the local monitoring and hands the data to the server which handles data storage, web server, and data processing.
    • Additional remote probes can be used to monitor various branch offices, for load-balancing, or similar. They send the monitoring data to the core server so that with just one installation of PRTG you can set up distributed monitoring with one central monitoring station. When monitoring multiple locations, you need at least one probe in each location.
