How to set the dsn of [inputs.sql] while using telegraf to connect MySQL?

I use docker-compose.yml to deploy MySQL, InfluxDB and Telegraf. I want to write the data of a MySQL database to an InfluxDB database through Telegraf. How to set the dsn of [inputs.sql] plugin while using telegraf to connect MySQL? Here are my settings: enter image description here enter image description here It is said the dsn should be set as followed:

username:password@protocol(address)/dbname?param=value

My config turn out to be wrong:

E! [telegraf] Error running agent: starting input inputs.sql: connecting to database failed: dial tcp 192.168.48.5:3306: connect: connection refused

Can you tell me how to fix it? Thank you very much.

Looks like there is connection issue there. Could you first test your MySQL connection from where the Telegraf agent is deployed?

  1. Open a terminal from where the Telegraf agent is deployed
  2. From inside the command prompt, type the command telnet 3306. In your case, that would be:

192.168.48.5:3306

  1. Hit enter to activate the command. If the MySQL service is running, you will receive a response from the server. If not, please make sure the MySQL is up and running and the firewall is clear.
