Types

type Collector

type Collector interface {
	Collect(datasource *Datasource) *dto.Stat
	Conf() Config
}

All collectors must satisfy collector.Collector interface

type Config

type Config struct {
	Cron    string `hcl:"cron"`
	Enabled bool   `hcl:"enabled"`
}

Config represents base configuration of each collector

type Cpu

type Cpu Config

Cpu collects statistics about CPU usage

func (*Cpu) Collect

func (c *Cpu) Collect(datasource *Datasource) *dto.Stat

Collect collects statistics from given datasource

func (*Cpu) Conf

func (c *Cpu) Conf() Config

Conf return the configuration of the collector

type Datasource

type Datasource struct {
	DsDto            *dto.Datasource
	PgStats          *pgstats.PgStats
	ConnectionString *string
}

Datasource contains information from where the collector should gather statistics
