Types ¶
type BlkIO ¶
type BlkIO struct {
TotalReadCount float64
TotalWriteCount float64
TotalReadBytes float64
TotalWriteBytes float64
}
BlkIO stands for Block I/O stats
type CPU ¶
type CPU struct {
CPUPercent float64
KernelPercent float64
UserPercent float64
UsedCores float64
LimitCores float64
UsedCoresPercent float64
ThrottlePeriods uint64
ThrottledTimeMS float64
}
CPU metrics
type DeviceMapperStats ¶ added in v1.6.0
type DeviceMapperStats struct {
DataAvailable uint64
DataUsed uint64
DataTotal uint64
DataUsagePercent float64
MetadataAvailable uint64
MetadataUsed uint64
MetadataTotal uint64
MetadataUsagePercent float64
}
DeviceMapperStats contains the stats of devicemapper storages driver type
func ParseDeviceMapperStats ¶ added in v1.6.0
func ParseDeviceMapperStats(info types.Info) (*DeviceMapperStats, error)
ParseDeviceMapperStats parses the output from the info DriverStatus info Array. This information is not consider stable by Docker and could change anytime according to API the docs.
type Memory ¶
type Memory struct {
UsageBytes uint64
CacheUsageBytes uint64
RSSUsageBytes uint64
MemLimitBytes uint64
UsagePercent float64 // Usage percent from the limit, if any
KernelUsageBytes uint64
SwapUsageBytes uint64
SwapOnlyUsageBytes uint64
SwapLimitBytes uint64
SwapLimitUsagePercent float64
SoftLimitBytes uint64
}
Memory metrics
type MetricsFetcher ¶
type MetricsFetcher struct {
// contains filtered or unexported fields
}
MetricsFetcher fetches the container system-level metrics from different sources and processes it to export metrics with business-value
func NewProcessor ¶
func NewProcessor(store persist.Storer, fetcher raw.Fetcher, inspector raw.DockerInspector, exitedContainerTTL time.Duration) *MetricsFetcher
NewProcessor creates a MetricsFetcher from implementations of its required components
func (*MetricsFetcher) Process ¶
func (mc *MetricsFetcher) Process(containerID string) (Sample, error)
Process returns a metrics Sample of the container with the given ID
func (*MetricsFetcher) WithRuntimeNumCPUfunc ¶ added in v1.9.0
func (mc *MetricsFetcher) WithRuntimeNumCPUfunc(rcFunc func() int)
WithRuntimeNumCPUfunc changes the NumCPU counting func so MetricsFetcher is mockable
