Metric | Definition | Unit |
Signal Strength (RSSI) | Instantaneous signal strength of a device's Wi-Fi radio. | -dBm |
Transmit Bitrate | Data rate of sent traffic to the local AP. | Mbps/Gbps |
Receive Bitrate | Data rate of received traffic from the local AP. | Mbps/Gbps |
Data Receive MCS | Negotiated data rate MCS index with HT/VHT/HE rates. | MCS Index Number |
Frame Retry Rate | Percentage of total Wi-Fi frames seen in the medium with the bit set. | % |
Channel Utilization | Ratio of busy time to free time of the spectrum as encountered by the sensor. | % |
QBSS Admission Capacity | Available capacity as reported by the local AP. | % |
QBSS Client Count | Total number of reported clients associated to the local BSSID. | Int |
QBSS Channel Utilization | Ratio of busy time to free time as reported by the local AP. | % |
AP Association Time | Total time taken from the first association request to the competition of the authentication exchange. | s |
DHCP Response Time | Total time to acquire a DHCP lease, measured from the first DHCP discover packet to the DHCP acknowledgment (ACK). | s |
DNS Lookup Time | Average response time for the resolution of the configured FQDN against both the primary and secondary DNS servers. | ms |
Latency | The RTT for either the ICMP or TCP ping configured for a particular service, namely the combined time to send to and receive a response from the target. | ms |
Packet Loss | The percentage of lost packets against a configured service seen when executing an ICMP or TCP ping. | % |
Jitter | Variation in latency results for a configured service. | ms |
HTTP Get (Elapsed time) | Time taken to execute an HTTP/S get against a configured target. | s |
Throughput (up / down) | Transfer rate of a specific throughput test (e.g., iPerf, Fast.com). | Mbps |
