Types

type Discovery

type Discovery struct {
	// contains filtered or unexported fields
}

Discovery provides service discovery functionality based on files that contain target groups in JSON or YAML format. Refreshing happens using file watches and periodic refreshes.

func NewDiscovery

func NewDiscovery(conf *SDConfig, logger log.Logger) *Discovery

NewDiscovery returns a new file discovery for the given paths.

func (*Discovery) Run

func (d *Discovery) Run(ctx context.Context, ch chan<- []*targetgroup.Group)

Run implements the Discoverer interface.

type SDConfig

type SDConfig struct {
	Files           []string       `yaml:"files"`
	RefreshInterval model.Duration `yaml:"refresh_interval,omitempty"`

	// Catches all undefined fields and must be empty after parsing.
	XXX map[string]interface{} `yaml:",inline"`
}

SDConfig is the configuration for file based discovery.

func (*SDConfig) UnmarshalYAML

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

UnmarshalYAML implements the yaml.Unmarshaler interface.

type TimestampCollector

type TimestampCollector struct {
	Description *prometheus.Desc
	// contains filtered or unexported fields
}

TimestampCollector is a Custom Collector for Timestamps of the files.

func NewTimestampCollector

func NewTimestampCollector() *TimestampCollector

NewTimestampCollector creates a TimestampCollector.

func (*TimestampCollector) Collect

func (t *TimestampCollector) Collect(ch chan<- prometheus.Metric)

Collect creates constant metrics for each file with last modified time of the file.

func (*TimestampCollector) Describe

func (t *TimestampCollector) Describe(ch chan<- *prometheus.Desc)

Describe method sends the description to the channel.
