Wi-Fi Verbose logging fields

The Android source code is available online.

Your log line appears to be from:

WifiStateMachine.java specifically String getLogRecString(Message msg)

Around line 2196, the string output starts looking similar to yours:

sb.append(" rssi=").append(mWifiInfo.getRssi());


sb.append(" f=").append(mWifiInfo.getFrequency());


sb.append(" sc=").append(mWifiInfo.score);


sb.append(" link=").append(mWifiInfo.getLinkSpeed());


sb.append(String.format(" tx=%.1f,", mWifiInfo.txSuccessRate));


sb.append(String.format(" %.1f,", mWifiInfo.txRetriesRate));


sb.append(String.format(" %.1f ", mWifiInfo.txBadRate));


sb.append(String.format(" rx=%.1f", mWifiInfo.rxSuccessRate));

The variables names appear reasonably descriptive for at least further research. The above file is dated 2017, given that there have been a number of WiFi changes made between OS version, I would find the one matching your version of OS, by looking for a "base" OS version branch (left hand side), and then drilling down to the appropriate WiFiStateMachine.java file:

or searching for an appropriate string where you can find where logging is occurring.
