collectors

type MetricsCollector ¶

type MetricsCollector interface {
	Run() error
}

MetricsCollector defines an interface that the various collectors must implement in order to collector, process, and present metrics to the caller or client. All collectors must use the MetricsMessage structure to receive metrics, and they must implement their own struct for handling configuration.

Further, although it isn't defined in this interface, it is recommended that collectors also create their own MetricsMessage channel to be used both in the implementation (e.g., &collectorImpl{}) and to be returned to the caller. Doing so ensures that we don't end up implementing too much in main(), instead opting to push the complexity down into the individual collectors.

type NodeInfo ¶

type NodeInfo struct {
	IPAddress string
	MesosID   string
	ClusterID string
	Hostname  string
}

NodeInfo represents information about the node, such as the IP address, hostname, Mesos ID, and the cluster ID that the node belongs to.
