```
|
||
|
|
[[outputs.mqtt]]
|
||
|
|
## URLs of mqtt brokers
|
||
|
|
servers = ["localhost:1883"]
|
||
|
|
|
||
|
|
## topic for producer messages
|
||
|
|
topic = "telegraf"
|
||
|
|
|
||
|
|
## QoS policy for messages
|
||
|
|
qos = 2
|
||
|
|
|
||
|
|
## username and password to connect MQTT server.
|
||
|
|
# username = "telegraf"
|
||
|
|
# password = "metricsmetricsmetricsmetrics"
|
||
|
|
|
||
|
|
## client ID, if not set a random ID is generated
|
||
|
|
# client_id = ""
|
||
|
|
|
||
|
|
## Timeout for write operations. default: 5s
|
||
|
|
# timeout = "5s"
|
||
|
|
## 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 output.
|
||
|
|
data_format = "influx"
|
||
|

|

|
### Required parameters:
|
||
|
|
|
||
|
|
* `servers`: List of strings, this is for speaking to a cluster of `mqtt` brokers. On each flush interval, Telegraf will randomly choose one of the urls to write to. Each URL should just include host and port e.g. -> `["{host}:{port}","{host2}:{port2}"]`
|
||
|
|
* `topic_prefix`: The `mqtt` topic prefix to publish to. MQTT outputs send metrics to this topic format "<topic_prefix>/<hostname>/<pluginname>/" ( ex: prefix/web01.example.com/mem)
|
||
|
|
* `qos`: The `mqtt` QoS policy for sending messages. See https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_9.0.0/com.ibm.mq.dev.doc/q029090_.htm for details.
|
||
|
|
|
||
|
|
### Optional parameters:
|
||
|
|
* `username`: The username to connect MQTT server.
|
||
|
|
* `password`: The password to connect MQTT server.
|
||
|
|
* `client_id`: The unique client id to connect MQTT server. If this paramater is not set then a random ID is generated.
|
||
|
|
* `timeout`: Timeout for write operations. default: 5s
|
||
|
|
* `ssl_ca`: SSL CA
|
||
|
|
* `ssl_cert`: SSL CERT
|
||
|
|
* `ssl_key`: SSL key
|
||
|
|
* `insecure_skip_verify`: Use SSL but skip chain & host verification (default: false)
|
||
|
|
* `data_format`: [About Telegraf data formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md)
