Collecting general RouterOS statistics using
...
scripts
You can also use scripts to structure MQTT messages that contain RouterOS statistics. Then, you can apply the scheduler to run the script whenever you like.
(to automate the process). For example, you can run a script like this (copy it the content of the RouterOS code shown below into a notepad and then into the script "source" field):
# Required packages: iot
################################ Configuration ################################
# Name of an existing MQTT broker that should be used for publishing
:local broker "my PC"

The script collects the data from the RouterOS (model name, serial number, RouterOS version, current CPU, used memory, free memory, and uptime) and publishes the message (the data) to the broker in the JSON format:
