Functions

func NewModule

func NewModule(base mb.BaseModule) (mb.Module, error)

func Round

func Round(val float64) (newVal float64)

Round rounds the given float64 value and ensures that it has a maximum of four decimal places.

Types

type CPUCoreMetrics

type CPUCoreMetrics CPUMetrics

CPUCoreMonitor is used to monitor the usage of individual CPU cores.

func (*CPUCoreMetrics) Percentages

func (m *CPUCoreMetrics) Percentages() CPUPercentages

Percentages returns CPU percentage usage information for the core. The values range from [0, 100%].

func (*CPUCoreMetrics) Ticks

func (m *CPUCoreMetrics) Ticks() CPUTicks

Ticks returns the raw number of "ticks". The value is a counter (though it may roll over).

type CPUCoresMonitor

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

CPUCoresMonitor is used to monitor the usage information of all the CPU cores in the system.

func (*CPUCoresMonitor) Sample

func (m *CPUCoresMonitor) Sample() ([]CPUCoreMetrics, error)

Sample collects a new sample of the metrics from all CPU cores.

type CPUMetrics

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

func (*CPUMetrics) NormalizedPercentages

func (m *CPUMetrics) NormalizedPercentages() CPUPercentages

NormalizedPercentages returns CPU percentage usage information that is normalized by the number of CPU cores (NumCPU). The values will range from 0 to 100%.

func (*CPUMetrics) Percentages

func (m *CPUMetrics) Percentages() CPUPercentages

Percentages returns CPU percentage usage information. The values range from 0 to 100% * NumCPU.

func (*CPUMetrics) Ticks

func (m *CPUMetrics) Ticks() CPUTicks

type CPUMonitor

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

CPUMonitor is used to monitor the overal CPU usage of the system.

func (*CPUMonitor) Sample

func (m *CPUMonitor) Sample() (*CPUMetrics, error)

Sample collects a new sample of the CPU usage metrics.

type CPUPercentages

type CPUPercentages struct {
	User    float64
	System  float64
	Idle    float64
	IOWait  float64
	IRQ     float64
	Nice    float64
	SoftIRQ float64
	Steal   float64
	Total   float64
}

type CPUTicks

type CPUTicks struct {
	User    uint64
	System  uint64
	Idle    uint64
	IOWait  uint64
	IRQ     uint64
	Nice    uint64
	SoftIRQ uint64
	Steal   uint64
}

type LoadAverages

type LoadAverages struct {
	OneMinute     float64
	FiveMinute    float64
	FifteenMinute float64
}

type LoadMetrics

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

func Load

func Load() (*LoadMetrics, error)

Load returns CPU load information for the previous 1, 5, and 15 minute periods.

func (*LoadMetrics) Averages

func (m *LoadMetrics) Averages() LoadAverages

Averages return the CPU load averages. These values should range from 0 to NumCPU.

func (*LoadMetrics) NormalizedAverages

func (m *LoadMetrics) NormalizedAverages() LoadAverages

NormalizedAverages return the CPU load averages normalized by the NumCPU. These values should range from 0 to 1.

type Module

type Module struct {
	mb.BaseModule
	HostFS string // Mountpoint of the host's filesystem for use in monitoring inside a container.
}
