wlan card load & SNMP

I already can read the load of the mikrotik cpu by SNMP using oid = .1.3.6.1.2.1.25.3.3.1.2.1. How can I read the load of the wlan card? - of course - if possible. I think there must be some times (too many clients for example?), when the wlan card performance can be a bottleneck.

/interface wireless registration-table print oid

gives values available on wireless Access Point for SNMP monitor.

/interface wireless print oid

gives values available on station (clients) for SNMP monitor.

Thank you - yes, I forget to write, that I’m looking for Access Point statistics. But this will print per-client OIDs (signals, rates, …), but I’m looking for overall wlan card statistics saying, if the wlan card is powerfull enough to manage clients requests - something like this (see below getting Mikrotik CPU usage example), but for the wlan card only.

[root@host locations]# snmpwalk -v1 -c public 192.168.0.15 .1.3.6.1.2.1.25.3.3.1.2.1
HOST-RESOURCES-MIB::hrProcessorLoad.1 = INTEGER: 2

if the wlan card is powerfull enough to manage clients requests - something like this (see below getting Mikrotik CPU usage example), but for the wlan card only.

RouterOS does not have such universal setting.

So is there any possibility how to somehow recognize, that 60 clients for example are too much for one wlan card? CPU load says nothing usable about that.
