Thanks to https://github.com/Art-of-WiFi API Version 2.0.11
Note Support for UniFi OS-based controllers (UniFi Dream Machine Pro or Cloud Key Gen2/Cloud Key Gen2 Plus with firmware version 2.0.24 or higher) has been added as of API version 1.1.47. The class automatically detects UniFi OS devices and adjusts URLs and several functions/methods accordingly. If your own code applies strict validation of the URL that is passed to the constructor, please adapt your logic to allow URLs without a port suffix when dealing with a UniFi OS-based controller. In case of my script use -P 443 and -s
NEW ==== New API Version Support for Accesspoints with 6GHz and Wifi 7
What a great script. It works like a charm and is easy to understand! I especially love the ability to check for updates ready to be installed. One minor thing is that I haven't been able to get warnings when you run Early Access update channel for your devices. But maybe it will come in a later version? :-) At any rate I highly recommend this script as it is by far the best way I have seen to integrate Ubiquiti/Unifi to nagios.
Hello, I tried to checkout this script on weekend but sadly on X-Mas the Whois entry of download URL was updated to some weird state - only NS entries are there, nothing more, so I even can't contact by email. And sadly there is no alternate download possible like here or github so I could only hope that it would be fixed when recognized. From uses PHP-client API the browser version looks very impresse what can bei all requested and monitored. Bests Reiner
Sorry, i wasn't a long time here, i have corrected it.
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
Please download the new Version 1.20210507 If it function please give me a feedback to [email protected], thanks
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.
it's implementated in the new version 1.20210427
why "OK" the "Current Status:" on the nagios webgui? >>>> Current Status: OK (for 0d 3h 58m 35s) Status Information: WARNING - Online: 1 - Offline: 1 Performance Data: AP=2 Online=1 Offline=1;0;1;; the query is correct: /usr/bin/php ./check_unifi.php -H 192.168.25.15 -u admin -p ********- -P 8443 -s -m ap -w 0 -c 1 WARNING - Online: 1 - Offline: 1 | AP=2 Online=1 Offline=1;0;1;;
The error has been corrected in the current version 1.20210308.
Thank you very much!! 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.
