Types ¶

type Exporter ¶

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

Exporter is a ebpf_exporter instance implementing prometheus.Collector

func New ¶

func New(configs []config.Config) (*Exporter, error)

New creates a new exporter with the provided config

func (*Exporter) Attach ¶

func (e *Exporter) Attach() error

Attach injects eBPF into kernel and attaches necessary programs

func (*Exporter) Collect ¶

func (e *Exporter) Collect(ch chan<- prometheus.Metric)

Collect satisfies prometheus.Collector interface and sends all metrics

func (*Exporter) CollectRaw ¶

func (e *Exporter) CollectRaw() (map[string][]RawMetric, error)

func (*Exporter) Describe ¶

func (e *Exporter) Describe(ch chan<- *prometheus.Desc)

Describe satisfies prometheus.Collector interface by sending descriptions for all metrics the exporter can possibly report

func (*Exporter) DescribeWrap ¶

func (e *Exporter) DescribeWrap()

func (*Exporter) MapsHandler ¶

func (e *Exporter) MapsHandler(w http.ResponseWriter, r *http.Request)

MapsHandler is a debug handler to print raw values of kernel maps
