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

PRTG Network Monitor offers a broad range of monitoring features covering bandwidth and network usage monitoring, as well as uptime monitoring.

  • More than 35 sensor types for comprehensive monitoring of small, medium and large networks.
    • SNMP: Sensors using the Simple Network Management Protocol (supports SNMP V1, V2c and V3)
      • SNMP Traffic: Supports monitoring of bandwidth (bits/s) and volume (bytes), as well as number of packets and errors via SNMP for a particular port or network card on PCs, servers, switches, firewalls, printers
      • SNMP Custom: Monitors one specific OID
      • SNMP Helper: SNMP Helper enables you to monitor thousands of performance counters on Windows systems (SNMP Helper agent must be installed on the device)
      • SNMP Library: SNMP libraries (which can be created from MIB files) make it easy to create specific sensors
      • Includes extensive OID libraries for quick monitoring setup for common OIDs.
      • Paessler’s own MIB compiler (freeware) can be used to load vendor specific MIB filess for use with PRTG 7
    • WMI: Sensors that use Windows built-in WMI (Windows Management Instrumentation) to access monitoring values
      • WMI CPU Load: Measures a system’s CPU load (total and per-CPU)
      • WMI Memory: Displays free system memory (MB and %)
      • WMI Disk Space: Free disk space on fixed drives (MB and % per drive)
      • WMI Network Card: Measures traffic going through network cards
      • WMI Page File: Checks the usage of the Windows page file
      • WMI Service: Checks if a service is running and optionally restarts a service if not
      • WMI Event Log Sensor: Monitors a system’s application, system and security event log for specific events
      • WMI Process: Monitors one process via WMI
      • WMI File: Monitors file size and existence, as well as changes to a file via WMI
      • WMI Query: Performs a custom WMI query
      • WMI Selection: Users can select from more than 20 different vital Windows system parameters (CPU: Percent Processor Time, CPU: Processor Queue Length, CPU: Processor Percent Privileged Time, CPU: Processor Percent User Time, Thread Context Switches, Memory: Free Physical Memory, Memory: Total Visible Memory, Memory: Pages/sec, Memory: Page Faults/sec, Memory: Page Reads/sec, Memory: Page Writes/sec, Memory: Pool Nonpaged bytes, Pagefile Usage, Disk: Percent Disk Time, Disk: Current Disk Queue Length, Disk: Reads/sec, Disk: Writes/sec, Network: Bytes Total/sec, Network: Bytes Received/sec, Network: Bytes Sent/sec, Server: Bytes Total/sec, Server: Bytes Received/sec, Server: Bytes Sent/sec, etc.)
      • WMI Exchange Server 2003: Monitors vital readings of an Exchange Server 2003
    • HTTP based services
      • HTTP: Monitors a web server via the HTTP protocol
      • HTTP Advanced: Monitors a web server via the HTTP protocol with various advanced settings (e.g. check a web page’s content or to use proxy server or authentication)
      • HTTP Transaction: Monitors a web server using a set of URLs to monitor whether logins or shopping carts are working properly
      • HTTP Content: Monitors a value returned by a HTTP request
    • Various TCP and UDP based services
      • PING: Performs one or more PINGs to monitor the availability of a device and optionally measure packet loss (in percent)
      • PORT: Checks the availability of TCP-based network services
      • FTP: Monitors the availability of a FTP server
      • DNS: Checks a DNS (Domain Name Service) server
      • SMTP: Monitors SMTP-based email servers (Simple Mail Transfer Protocol)
      • POP3: Monitors POP3-based email servers (Post Office Protocol V3)
      • IMAP: Monitors IMAP -based email servers (Internet Message Access Protocol)
      • RDP (Remote Desktop): Checks the availability of a device’s RDP service
    • SQL Servers
      • Microsoft SQL Server: Checks Microsoft SQL Server connections
      • MySQL Server: Checks MySQL Server connections
      • Oracle SQL Server: Checks Oracle SQL Server connections
    • NetFlow
      • NetFlow: Monitors Cisco switches using NetFlow V5
      • NetFlow (Custom): User configurable version of the NetFlow sensor
    • Packet Sniffing
      • Packet Sniffer (Header): Looks at the headers of the data packets to account traffic by IP, by port, by protocol, etc.
      • Packet Sniffer (Content): Reassembles data packets to streams and looks into the payload data of the streams to assess the type of traffic (e.g. SMTP, HTTP, IMAP, file sharing, NETBIOS, etc.)
      • Packet Sniffer (Custom): Accounts packet data implementing user-specific rules
    • Custom Sensors: users can create their own sensor types using scripting and programming languages, as well as custom WQL (WMI Query Language) scripts
  • “Smart” sensors that e.g. automatically discover quad-core CPUs, allowing to monitor the total CPU load, as well as the individual cores
  • PRTG automatically monitors the “system health” of the core server and of each probe in order to discover overloading situations or badly configured systems that may distort monitoring results.
  • Various means of alerting and notifications (email, SMS, pager message, HTTP request, event log, etc.). Notifications can be triggered by individually definable parameters and contain various entries of releveant information.
