The Manager interface defines operations for starting a manager and getting container and machine information.

func New

func New(memoryCache *memory.InMemoryCache, sysfs sysfs.SysFs, maxHousekeepingInterval time.Duration, allowDynamicHousekeeping bool, ignoreMetricsSet container.MetricSet, collectorHttpClient *http.Client) (Manager, error)

New takes a memory storage and returns a new manager.
