+# 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]]}]}]
