Telegraf: input.mqtt_consumer metric parse error

[yn1v]

Relevant telegraf.conf:

[[inputs.mqtt_consumer]]
servers = ["tcp://zancudo.sytes.net:1883"]
qos = 0
connection_timeout = "30s"
topics = [
"teodolinda/gerencia/temp",
"teodolinda/gerencia/humidity",
"teodolinda/recepcion/temp",
]
persistent_session = false
client_id = ""
data_format = "influx"

System info:

Fedora 29
telegraf-1.9.2-1.x86_64
influxdb-1.7.3-1.x86_64
kernel-4.18.16-300.fc29.x86_64

Steps to reproduce:

systemctl start influxdb.service
systemctl start telegraf.service
systemctl status telegraf.service

Expected behavior:

messages get into influxdb

Actual behavior:

Jan 19 23:51:33 localhost.localdomain telegraf[1814]: 2019-01-20T05:51:33Z I! [inputs.mqtt_consumer] Connected [tcp://zancudo.sytes.net:1883]

Additional info:

Telegraf is working as I can see data in Chronograf from the system (cpu, disk, mem).
I was looking if I needed some configuration for the values, but I find this "There are no additional configuration options for InfluxDB line protocol. The metrics are parsed directly into Telegraf metrics."
I saw issue #4463 that it is similar, but it was not resolved.

It looks like the data in mqtt is not formatted as expected, when set to data_format = "influx" the plugin is expecting line protocol.

From the log message it looks like you have raw values. Try using the value data_format by adding these lines instead of data_format = "influx":

data_format = "value"
data_type = "float"
