How to get it working with UniFi-CloudKey-Gen2-Plus? I can see from the review on February 5, 2021, that the user darco was able to get it working with Gen2 CloudKey. But unfortunately darco didn't specify, how he got it working...
What I do know is that Gen2 is not using port 8443 anymore, but access is done straight to HTTPS/443 port.
And I'm able to query the device info from the browser from:
https://[local-IP-of-Gen2-CloudKey]/proxy/network/api/s/default/stat/device

Is it possible to get the total number of connected wifi clients with a nagios/centreon compatible check? The console check works fine but it would be great to get a counter inside the monitoring system.
Owner's reply
it's implementated in the new version 1.20210427

why "OK" the "Current Status:" on the nagios webgui?

The error has been corrected in the current version 1.20210308.
Thank you very much!!
I've just tested with UniFi-CloudKey-Gen2-Plus
I've just tested with UniFi-CloudKey-Gen2-Plus
Downloaded the files and adjusted the clients.php
But then the skript does nothing. I can even use the example:
# usr/bin/php usr/local/nagios/libexec/check_unifi.php -H 192.168.2.1 -u USER -p PASS -P 8443 -s -m uplink -a AP01 -w 200 -c 100
And get nothing.
Any ideas?
(sorry, rating required)

Unfortunately I don't know which version is in use. A config.php is no longer required.
