# 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 UNIX domain sockets and authentication:
# DATA_SOURCE_NAME="prometheus:nopassword@unix(/run/mysqld/mysqld.sock)/"

# Using a TCP connection and password authentication:
# DATA_SOURCE_NAME="login:password@(hostname:port)/dbname"

# 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.
# ARGS='-config.my-cnf /etc/mysql/debian.cnf'

# Usage of prometheus-mysqld-exporter:
#   -collect.auto_increment.columns
#     	Collect auto_increment columns and max values from information_schema
#  --exporter.lock_wait_timeout=2
#       Set a lock_wait_timeout on the connection to avoid long metadata

#       supported by Oracle MySQL.
