responses for discovery return variable list length

[hudecof]

hi,

I'm experiencing following problem, both with unifi_miner.pl and unify_proxy.pl.

[PROD] phudec@dmplapps02: ~ $ zabbix_get -s diplapps06.cnc.sk -k unifi.proxy[discovery,wlan]
{"data":[]}
[PROD] phudec@dmplapps02: ~ $ zabbix_get -s diplapps06.cnc.sk -k unifi.proxy[discovery,wlan]
{"data":[{"{#SITEID}":"562001260cf28b7adb2609d2","{#NAME}":"CNC-GUEST","{#SITENAME}":"by486k0l","{#ISGUEST}":"0","{#ID}":"562001880cf28b7adb2609e0","{#SITEDESC}":"CNC"}]}
[PROD] phudec@dmplapps02: ~ $ zabbix_get -s diplapps06.cnc.sk -k unifi.proxy[discovery,wlan]
{"data":[{"{#SITENAME}":"by486k0l","{#SITEID}":"562001260cf28b7adb2609d2","{#NAME}":"CNC-GUEST","{#ID}":"562001880cf28b7adb2609e0","{#ISGUEST}":"0","{#SITEDESC}":"CNC"},{"{#SITEDESC}":"DCP","{#SITEID}":"562002230cf28b7adb2609e4","{#NAME}":"DCP-GUEST","{#SITENAME}":"16gwksl1","{#ISGUEST}":"0","{#ID}":"562002650cf28b7adb2609f3"},{"{#SITEID}":"562002230cf28b7adb2609e4","{#NAME}":"CNC-DCP","{#SITENAME}":"16gwksl1","{#ISGUEST}":"0","{#ID}":"562002a40cf28b7adb2609f5","{#SITEDESC}":"DCP"}]}

I run 3 times the same command and the respnse is

• 0 ittems
• 1 item
• 3 items

I suppose the problem is on the contorller side or some caching problem with the perl.

CONTROLLER VERSION: 5.7.23

Hello Peter.

You can disable cache feature for some tests - just use "... -с 0" option for unifi_miner.pl and it will be connect to UniFi Controller every time to get JSON. If you find no errors, use "... -d 3 > log,txt" option for looking to cache reading results. Value '3' will generate a few log lines, but can be very helpfull.

So... if you use unifi_miner.pl via UserScript, may be you need to increase Agent's Timeout value.

Debug mode for the unifi_miner.pl shows

The log form the unify controller

But for time to time it worksand I could retrieve full data set.

my monitoring user is read-only with Allow read only access to all sites permission

[zbx-sadman]

Peter, try to use UniFi admin account for API access just for test.

[hudecof]

works as expected, I was not able reproduce the issue. I chage the role to SuperAdmin role

[zbx-sadman]

Okay...

I did not install v5.7.23 and do not know how works "Allow read only access to all sites" option. On old releases of UniFi Controller i had to add readonly user with name stat to every site (with the same password) to avoid "403 forbidden" error.
