Hello,
I have a Prometheus instance up and am trying to figure out the best route to get my IOT sensor data into it.
My devices publish a JSON to a MQTT topic every minute and I'm uncertain about the best practices on how to ingest or scrape these metrics. After reading the documentation, using the push-gateway and subscribing to a topic via a service seem frowned upon. I had an idea of pointing my MQTT messages at AWS Kineses or DynamoDB and then writing a exporter to hit those resources, am I on the right track?
Can someone with some more experience recommend another way? Or is it okay to use the push-gateway in this case?
Appreciate any help I can get!
Cheers. Stay healthy out there.

hi A R,
I haven't set it up myself yet, but was thinking about the same use case.
What I've found is that there are mqtt/prome gateways - that work kind of like pushgateway:
the general idea is that the exporter subscribes to the mqtt topic and exposes it as a metric for prome (keeping the last published value from mqtt in memory)
hth,
