type StatsEntry 

type StatsEntry struct {
	Container        string
	Name             string
	ID               string
	CPUPercentage    float64
	Memory           float64 // On Windows this is the private working set
	MemoryLimit      float64 // Not used on Windows
	MemoryPercentage float64 // Not used on Windows
	NetworkRx        float64
	NetworkTx        float64
	BlockRead        float64
	BlockWrite       float64
	PidsCurrent      uint64 // Not used on Windows
	IsInvalid        bool
}

StatsEntry represents the statistics data collected from a container

type StatsOptions 

type StatsOptions struct {
	// All allows including both running and stopped containers. The default
	// is to only include running containers.
	All bool

	// NoStream disables streaming stats. If enabled, stats are collected once,
	// and the result is printed.
	NoStream bool

	// NoTrunc disables truncating the output. The default is to truncate
	// output such as container-IDs.
	NoTrunc bool

	// Format is a custom template to use for presenting the stats.
	// Refer to [flagsHelper.FormatHelp] for accepted formats.
	Format string

	// Containers is the list of container names or IDs to include in the stats.
	// If empty, all containers are included. It is mutually exclusive with the
	// Filters option, and an error is produced if both are set.
	Containers []string

	// Filters provides optional filters to filter the list of containers and their
	// associated container-events to include in the stats if no list of containers
	// is set. If no filter is provided, all containers are included. Filters and
	// Containers are currently mutually exclusive, and setting both options
	// produces an error.
	//
	// These filters are used both to collect the initial list of containers and
	// to refresh the list of containers based on container-events, accepted
	// filters are limited to the intersection of filters accepted by "events"
	// and "container list".
	//
	// Currently only "label" / "label=value" filters are accepted. Additional
	// filter options may be added in future (within the constraints described
	// above), but may require daemon-side validation as the list of accepted
	// filters can differ between daemon- and API versions.
	Filters *filters.Args
}

StatsOptions defines options for RunStats.
