Hello, i installed unifi_proxy on my zabbix server.

Then i import template to my zabbix, i noticed that there is 11 groups of data elements and 11 data element (i suppose there must be more).

Zabbix - 3.2.1

So.. Do u see any values in Zabbix's Latest data? Do you turn on Active mode on Zabbix Agent?

After some time (like 2 hours) lastest data started to show, but it has really big latency (like 10min between checks on UniFi Access Points (1395 data elements)). Is there any way to increase speed of update or decrease number of items for each AP monitored? unifi_proxy settings:

MaxClients=100
StartServers=8
MaxRequestsPerChild=2048
CacheMaxAge=200

UniFi Proxy/Miner have no slowdown features implemented.

You can control CacheMaxAge option only. The script compare request processing start time and the cache file creation time. If the time is different more than CacheMaxAge (sec) - actual data is fetched from the UniFi controller and the cache file is recreated. You can clean CacheDir and wait for little time. Then you will see new cache files. Or you can just do ls from time to time to see changing of the cache file creation time.

Update interval for the UniFi Access Points discovery rule (see Zabbix's LLD feature) is 10min. If you adopt the new UAP - its will be found in 0...10 minutes. But all "old" UAP's metrics stay polled with max latency in CacheMaxAge+Item update interval sec.

The number of active Zabbix data items te can be reduced by turning off Item prototypes in the UniFi Access Points discovery rule that contained in the Template UBNT UniFi Controller.

Also, i think that StartServers=8 is so much. Every Proxy instance is required ~50-60mb of RAM (yes, it's Perl ;). One Server thread can serve ~1000 req/sec (if CPU is fast enought.)

Well, RAM Usage is not very big problem for me :) I'll play with some settings and if i can manage to work zabbix properly, i will sent a reply! Thanks for help!
