Functions

func NewDebugFsStatCollector

func NewDebugFsStatCollector() prometheus.Collector

NewDebugFsStatCollector creates a DebugFsStatCollector

func NewEBPFErrorsCollector

func NewEBPFErrorsCollector() prometheus.Collector

NewEBPFErrorsCollector initializes a new Collector object for ebpf helper and map operations errors. Not supported on Windows, thus returning noop collector instead.

func NewPerfUsageCollector

func NewPerfUsageCollector() prometheus.Collector

NewPerfUsageCollector creates a prometheus.Collector for perf buffer and ring buffer metrics

func ReportPerfMapTelemetry

func ReportPerfMapTelemetry(pm *manager.PerfMap)

ReportPerfMapTelemetry starts reporting the telemetry for the provided PerfMap

func ReportRingBufferTelemetry

func ReportRingBufferTelemetry(rb *manager.RingBuffer)

ReportRingBufferTelemetry starts reporting the telemetry for the provided RingBuffer

func UnregisterTelemetry

func UnregisterTelemetry(m *manager.Manager)

UnregisterTelemetry unregisters the PerfMap and RingBuffers from telemetry

Types

type NoopDebugFsStatCollector

type NoopDebugFsStatCollector struct{}

NoopDebugFsStatCollector implements the prometheus Collector interface but does nothing

func (*NoopDebugFsStatCollector) Collect

func (c *NoopDebugFsStatCollector) Collect(chan<- prometheus.Metric)

Collect returns the current state of all metrics of the collector

func (*NoopDebugFsStatCollector) Describe

func (c *NoopDebugFsStatCollector) Describe(chan<- *prometheus.Desc)

Describe returns all descriptions of the collector
