Is there any place where I could find the meaning of the metrics exposed to prometheus ? And more esoecially, what is the period of timle over which measurements are made ?
An example for that metric:
# HELP backend_mqtt_command_count The number of published commands by the MQTT backend (per command).
# TYPE backend_mqtt_command_count counter
-> What are the “per command” ?
-> Over which period are measured the 905 ?
