sends metric data. Hosts that receive all of the metrics data can display this data and can pass the condensed form of the data to the hierarchy. It is precisely because of this hierarchical pattern that the Ganglia can be extended well. Gmond brings very little system load, which makes it a piece of code that runs on each computer in the cluster without impacting user performance. The multiple collection of all this data can affect node performance. The "jitter" in the network occurs when a la
