Test influxdb integration

This script starts two EMQX nodes and a influxdb server in docker container. The bootstraping rule engine and data bridge config is provided in influx-bridge.conf which got included in the bootstraping config bundle emqx.conf.

Start the cluster

./start.sh

How to run tests

The rule and bridge are configured to pipe data from MQTT topic t/# to the 'myvalues' measurement in the 'mqtt' bucket.

Manual verification steps

• Start the cluster
• Send mqtt messages to topic /t/a with a JSON object as MQTT paylaod like {"value": 1}
• Observe data in influxdb curl -k -H 'Authorization: Token abcdefg' -G 'https://localhost:8086/query?pretty=true' --data-urlencode "db=mqtt" --data-urlencode "q=SELECT * from myvalues"

Example output the curl query against influxdb:

{"results":[{"statement_id":0,"series":[{"name":"myvalues","columns":["time","clientid","value"],"values":[["2023-02-28T11:13:29.039Z","a1",123]]}]}]
