The node also provide zbus interfaces to query some of the node information.

Zbus

Node module is available on zbus over the following channel

Example

//SystemMonitor interface (provided by noded)
type SystemMonitor interface {
	NodeID() uint32
	Memory(ctx context.Context) <-chan VirtualMemoryStat
	CPU(ctx context.Context) <-chan TimesStat
	Disks(ctx context.Context) <-chan DisksIOCountersStat
	Nics(ctx context.Context) <-chan NicsIOCounterStat
}

// HostMonitor interface (provided by noded)
type HostMonitor interface {
	Uptime(ctx context.Context) <-chan time.Duration
}

// Events interface
type Events interface {
	PublicConfigEvent(ctx context.Context) <-chan PublicConfigEvent
	ContractCancelledEvent(ctx context.Context) <-chan ContractCancelledEvent
}
