Hi! So I've got 20 pieces of MikroTik SXT LTE6 kit RBSXTR&R11E-LTE6 on the city, connected to 1 server and I need to collect data such as usage of medium and signal strength of every single one. I think using Zabbix would be the best option to solve the problem. Have You ever try to do such a thing, and maybe someone has some advice? Not gonna lie I'm new to stuff like this and found Zabbix on the web as an easy and free tool to do such things

The Mikrotik devices support SNMP so you can use any industry standard tool that you choose. For example at home I use PRTG and as well as traffic statistics it collects signal strength parameters RSRP, RSRQ and SINR from the SXT LTE router.

Yeah you're right, but unfortunately, I need a totally free tool, cannot be on any trial etc.

Simply use The Dude, can be perfectly used for that, but not expect help from me, just because I suggest it to you, because require much time for non-standard configuration.

For now they are no HowTo guide about it.
