Automatically create the database when writing data with the schemaless feature if set to true.

Configuring taosAdapter

Enable the configuration in the taosAdapter configuration file (default location /etc/taos/taosadapter.toml)

# Automatically create the database when writing data with the schemaless feature if set to true.
smlAutoCreateDB = true
[influxdb]
enable = true

The smlAutoCreateDB configuration item is used to enable the automatic database creation feature. When set to true, taosAdapter will automatically create the corresponding database upon receiving data if it does not already exist.

Configuring Telegraf

In the Telegraf configuration file (default location /etc/telegraf/telegraf.conf), add the configuration for the outputs.http output module:

[[outputs.http]]
  url = "http://<taosAdapter's host>:<REST service port>/influxdb/v1/write?db=<database name>"
  ...
  username = "<TDengine's username>"
  password = "<TDengine's password>"
  ...

Where <taosAdapter's host> should be filled with the domain name or IP address of the server running the taosAdapter service, <REST service port> should be filled with the port of the REST service (default is 6041), <TDengine's username> and <TDengine's password> should be filled with the actual configuration of the running TDengine, and <database name> should be filled with the database name where you want to save Telegraf data in TDengine.

Example as follows:

[[outputs.http]]
  url = "http://127.0.0.1:6041/influxdb/v1/write?db=telegraf"
  method = "POST"
  timeout = "5s"
  username = "root"
  password = "taosdata"
  data_format = "influx"
