- "probe_no" (line 145) should match the number assigned to the testtools of the particular WiFiMon Hardware Probe (WHP), e.g. for the WHP assigned the number 1, the value should be "1". Assigning numbers to WHPs is possible by appropriately setting the testtool attribute included in the websites monitored by them. More information related to assigning number to WHPs is available in the WiFiMon Test Server installation guide.
- "WAS_FQDN" (line 128) should match the FQDN of the WiFiMon Analysis Server (WAS) responsible for processing the wireless performance metrics of the WHP. The above code block assumes that the WAS uses https and port 443.
- LInes 133 to 135 can be filled with more information regarding the location of the WHP.
