0.15.0 / 2023-06-16

BREAKING CHANGES:

The exporter no longer supports the monolithic DATA_SOURCE_NAME environment variable. To configure connections to MySQL you can either use a my.cnf style config file or command line arguments.

For example:

export MYSQLD_EXPORTER_PASSWORD=secret
mysqld_exporter --mysqld.address=localhost:3306 --mysqld.username=exporter

We have also dropped some internal scrape metrics:

  • mysql_exporter_scrapes_total
  • mysql_exporter_scrape_errors_total
  • mysql_last_scrape_failed

The default client configuration file is now .my.cnf in the process working directory. Use --config.my-cnf="$HOME/.my.cnf" to retain the previous default.

Changes:

  • [CHANGE] Allow tlsCfg.InsecureSkipVerify outside of mTLS #631
  • [CHANGE] Update to exporter-toolkit v0.8.1 #677
