Get SSID of WLAN Client with newer Accesspoints (APX)

Hello,

I'd like to collect and analyze the wireless logs. Older accesspoints send in nice logs like this one:

2020:11:11-17:13:01 <AP_ID> awelogger[9274]: id="4104" severity="info" sys="System" sub="WiFi" name="STA association" ssid="mySSID" ssid_id="WLAN2.1" bssid="<MAC>" sta="<MAC>" status_code="0"

I can get the clients MAC, the action (STA assoc) and the Accesspoint ID from it in an easy parsable format.

Unfortunately the newer accesspoints logs are looking like this:

<30>2020:11:11-09:01:30 <AP_ID> hostapd: ath001: STA xx:xx:xx:xx:xx:xx WPA: pairwise key handshake completed (RSN)
<30>2020:11:11-09:01:30 <AP_ID> hostapd: ath001: STA xx:xx:xx:xx:xx:xx RADIUS: starting accounting session 42F1A88A-00000067
<30>2020:11:11-09:01:29 <AP_ID> hostapd: ath001: STA xx:xx:xx:xx:xx:xx IEEE 802.11: associated

Does someone know if and how I could get the SSID for clients that are connected to an APX series accesspoint? I know, I could ask the API / cc AFTER my client is connected, but then all the logs are already processed.

Regards,

Daniel
