changelog如下
Breaking changes This release contains major breaking changes to metric names. Many metrics have new names, labels, and label values in order to conform to current naming conventions. Linux node_cpu metrics now break out guest values into separate metrics. See Issue #737 Many counter metrics have been renamed to include _total. Many metrics have been renamed/modified to include base units, for example node_cpu is now node_cpu_seconds_total.
