Enhanced Feature Overview: Architecture and Performance

Cette page n’existe pas en français en ce moment. Nous vous prions de nous excuser.

Using all our experience gathered from PRTG Traffic Grapher and IPCheck Server Monitor, we wrote PRTG Network Monitor from the scratch, setting clear foci on performance and user friendliness.

  • Modern, powerful software engine
  • Scales up to several 10,000 sensors per installation
  • Allows load distribution using remote probes for CPU-intensive monitoring, e.g. packet sniffing
  • PRTG Network Monitor consists of three main parts:
    • PRTG Core Server: The central part of a PRTG installation is the “Core Server”, including data storage, web server, report engine and notification system.
    • PRTG Probe: A “probe” performs the actual monitoring. It receives its configuration from the Core Server, runs the monitoring processes and returns monitoring results to the Core Server. A Core Server can manage an unlimited number of probes in order to achieve multi-location monitoring.
    • PRTG Web Interface: The user interface is entirely web-based. Users access the configuration and monitoring results using a standard web browser.
  • Core and probe are Windows services which are run by the Windows system without the requirement for a user to be logged in.
  • Probes are able to work independently of the Core Server, e.g. in case the connection between probe and core is lost due to connectivity problems. The probe buffers the data, automatically reconnects to the Core as soon as it is available again and transmits all monitoring results gathered during the connection loss, so no information is lost.
