+# By default the connection string will be read from
+# $HOME/my.cnf or from the file specified with the -config.my-cnf parameter.
+
+# To set a connection string from the environment instead, uncomment one of the
+# following lines.
+
+# Using a TCP connection and password authentication:
+# DATA_SOURCE_NAME="login:password@(hostname:port)/dbname"
+
+# Using UNIX domain sockets and authentication:
+DATA_SOURCE_NAME="prometheus:nopassword@unix(/run/mysqld/mysqld.sock)/"
+
+# Note the user must be granted enough privileges for the exporter to run.
+# Example to create a user to connect with the UNIX socket:
+#
+#  CREATE USER IF NOT EXISTS 'prometheus'@'localhost' IDENTIFIED VIA unix_socket;
+#  GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'prometheus'@'localhost';

+# Set the command-line arguments to pass to the exporter.
