var DefaultConfig = Config{
	LockWaitTimeout: 2,

	InfoSchemaProcessListProcessesByUser: true,
	InfoSchemaProcessListProcessesByHost: true,
	InfoSchemaTablesDatabases:            "*",

	PerfSchemaEventsStatementsLimit:     250,
	PerfSchemaEventsStatementsTimeLimit: 86400,
	PerfSchemaEventsStatementsTextLimit: 120,
	PerfSchemaFileInstancesFilter:       ".*",
	PerfSchemaFileInstancesRemovePrefix: "/var/lib/mysql",

	HeartbeatDatabase: "heartbeat",
	HeartbeatTable:    "heartbeat",
}

DefaultConfig holds the default settings for the mysqld_exporter integration.

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.

Config controls the mysqld_exporter integration.

func (*Config) InstanceKey

func (c *Config) InstanceKey(_ string) (string, error)

InstanceKey returns network(hostname:port)/dbname of the MySQL server.

func (*Config) Name

func (c *Config) Name() string

Name returns the name of the integration that this config represents.

func (*Config) NewIntegration

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

NewIntegration converts this config into an instance of an integration.

func (*Config) UnmarshalYAML

func (c *Config) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements yaml.Unmarshaler for Config.
