Graphite Returns 所有值，而不是函数

Question

假设我有以下查询：

http:/graphite.server:####/render?&target=highestCurrent(metric.path.value,3)

我运行关注 Graphite 返回指标中所有值的问题，而不是最后三个 "highest current"。

我找不到端到端的示例。通常，它们仅包含：&target=...，因此我假设这只是 "supposed to work."

问题的可能来源是什么？

Answer 1

它应该绘制所有 3 个最高值 metrics/series。一个系列中没有 3 个指标。

highestCurrent(seriesList, n)

Takes one metric or a wildcard seriesList followed by an integer N. Out of all metrics passed, draws only the N metrics with the highest value at the end of the time period specified.

Example:

&target=highestCurrent(server*.instance*.threads.busy,5)

Draws the 5 servers with the highest busy threads.
