The MQTT consumer plugin reads from specified MQTT topics and adds messages to InfluxDB. The plugin expects messages in the Telegraf Input Data Formats.
# Read metrics from MQTT topic(s)
[[inputs.mqtt_consumer]]
servers = ["localhost:1883"]
## MQTT QoS, must be 0, 1, or 2
qos = 0
## Topics to subscribe to
topics = [
"telegraf/host01/cpu",
"telegraf/+/mem",
"sensors/#",
]
# if true, messages that can't be delivered while the subscriber is offline
# will be delivered when it comes back (such as on service restart).
# NOTE: if true, client_id MUST be set
persistent_session = false
# If empty, a random client ID will be generated.
client_id = ""
## username and password to connect MQTT server.
# username = "telegraf"
# password = "metricsmetricsmetricsmetrics"
## Optional SSL Config
# ssl_ca = "/etc/telegraf/ca.pem"
# ssl_cert = "/etc/telegraf/cert.pem"
# ssl_key = "/etc/telegraf/key.pem"
## Use SSL but skip chain & host verification
# insecure_skip_verify = false
## Data format to consume.
## Each data format has its own unique set of configuration options, read

- All measurements are tagged with the incoming topic, ie
