Types

type DBMetrics

type DBMetrics struct {
	Tables    map[string]*TableMetrics
	SizeBytes *metrics.Gauge
}

DBMetrics - includes metrics for dbs and a mapping to tables in the db

type ModeMetrics

type ModeMetrics struct {
	Locks *metrics.Gauge
}

ModeMetrics - metrics on lock modes

type PostgresStat

type PostgresStat struct {
	Metrics *PostgresStatMetrics

	DBs   map[string]*DBMetrics
	Modes map[string]*ModeMetrics

	PGDATA string
	// contains filtered or unexported fields
}

PostgresStat stores info on the db

func New

func New(m *metrics.MetricContext, user, config string) (*PostgresStat, error)

Opens connection to postgres database and starts collector for metrics

func (*PostgresStat) CallByMethodName

func (s *PostgresStat) CallByMethodName(name string) error

CallByMethodName searches for a method implemented by s with name. Runs all methods that match names.

func (*PostgresStat) Close

func (s *PostgresStat) Close()

Closes database connection

func (*PostgresStat) Collect

func (s *PostgresStat) Collect()

runs metrics collections
