Functions

func GetScrapers

func GetScrapers(c *Config) []collector.Scraper

GetScrapers returns the set of *enabled* scrapers from the config. Configurable scrapers will have their configuration filled out matching the Config's settings.

func New

func New(log log.Logger, c *Config) (integrations.Integration, error)

New creates a new mysqld_exporter integration. The integration scrapes metrics from a mysqld process.
