SonicOS/X 7 SD-WAN
About Performance Probes
Network path performance metrics are determined using SD-WAN performance probes, which are similar to Network Monitor Probes. SonicOS supports ICMP and TCP probe types. An SD-WAN performance probe can be used by multiple Path Selection profiles (for further information, see About Path Selection Profiles; for a description of SonicOS SD-WAN and its features, see About SD-WAN.).
The Network| SD-WAN > SLA Probes page shows the dynamic performance data (latency/jitter/packet loss) and probe status for each path (interface) in the SD-WAN group, in both tabular and graphic displays. The display can show data for the last minute (default), last day, last week, or last month.
| # | Number of the probe. The Collapse/Expand icon toggles the display of the graphs. |
| NAME | Name of the SD-WAN performance probe. |
| SD-WAN GROUP | Name of the SD-WAN group associated with the SD-WAN performance probe. Mousing over the entry displays properties about the SD-WAN group. |
| PROBE TARGET | Target address object of the SD-WAN performance probe. Mousing over the entry displays the host address. |
| PROBE TYPE |
Type of performance probe:
When - TCP – Explicit Route is selected along with the RST Response Counts as Miss field, the Port field also becomes available. |
| PORT |
Port for the SD-WAN performance probe. The minimum/maximum values are 1 to 65535. Ports are displayed only for TCP - Explicit Route probe types. A hyphen (–) displays for Ping - Explicit Route probe types. |
| INTERVAL (S) | Time between SD-WAN performance probes, in seconds. |
| LATENCY (MS) | Round trip delay for the probes sent through a particular path/interface to reach the probe target and acknowledge back, in milliseconds. This is also displayed as a graph below the probe’s entry in the Performance Probe table. |
| JITTER (MS) | Variation in the latency measurements for the probes through a particular path/interface, in milliseconds. This is also displayed as a graph below the probe’s entry in the Performance Probe table. |
| PACKET LOSS (%) | Percentage of probes that are missed of the probes sent through a particular path/interface. This is also displayed as a graph below the probe’s entry in the Performance Probe table. |
| ADDITIONAL INFO | When you hover over the icon, you can view the data for the following: Response timeout, Success Threshold, Failure Threshold, & RST in Failure. |
| COMMENTS |
Displays the comment entered when the performance probe was configured. |
