  • Jitter

    Jitter in network monitoring is the variation in packet delay over time, a key quality metric for voice, video and other real-time traffic.

  • Latency

    Latency in network monitoring is the time a packet or request needs to travel between two points, measured in milliseconds as one-way or round-trip delay.

  • NetFlow

    NetFlow is a flow-export protocol in which routers and switches summarize traffic into records showing who talked to whom, how much and when.

  • Packet capture

    Packet capture is the recording of network packets as they cross an interface, saved to a file for detailed protocol analysis and troubleshooting.

  • Packet loss

    Packet loss is the share of network packets that never reach their destination, a key network monitoring metric for congestion, faults and poor quality.

  • SNMP

    SNMP is the standard protocol for polling and receiving status data from network devices, used in network monitoring to track interfaces, load and faults.

  • Wireshark

    Wireshark is an open-source network protocol analyzer that captures packets and decodes them field by field for troubleshooting and security analysis.
