Message bus design and naming #2

Open vielmetti opened 4 years ago

vielmetti commented 4 years ago

NATS has a fairly flexible naming scheme for channels. Think about how to name things.

My first pass at a naming was to put the temperature from the qwiic sensor at

temp.attic.qwiic: 86.90

There's more than one way to do it. Do I anticipate the need for more than a 3-level hierarchy? Should the data be self-describing, with a JSON object?

Review this when I have 10 sensors reporting.

Time to review https://github.com/SweBarre/mqtt2prom

Prometheus data looks like

# HELP sensor_temperature_celsius Temperature in celsius
# TYPE sensor_temperature_celsius gauge
sensor_temperature_celsius{instance="computer_room",job="zigbee",sensorid="computer_room"} 19.8
sensor_temperature_celsius{instance="kitchen",job="rfxcom",sensorid="kitchen"} 21.8
sensor_temperature_celsius{instance="laundry",job="zigbee",sensorid="laundry"} 19.84
sensor_temperature_celsius{instance="outside",job="rfxcom",sensorid="backside"} 5.9

which in my model would map to

temp.kitchen.rfxcom: 21.8
temp.laundry.zigbee: 19.84
temp.computer_room.zigbee: 19.8
temp.outside.rfxcom: 5.9
