如何在 Grafana 中绘制值的倒数？

Question

How can I plot the 1/series in Grafana? The docs show scale , which allows multiplying by a constant, and divideSeries which allows you to divide two series by each other, but there doesn't seem to be a way to divide a constant by a series.

Answer 1

一个简单的解决方法是添加第二个查询 constantLine(1)，然后添加第三个查询，将第二个查询除以第一个，然后隐藏前两个查询，您应该很好地使用第三个查询。

Answer 2

Grafana supports the invert function, as described in the docs .

"Takes one metric or a wildcard seriesList, and inverts each datapoint (ie 1/x)."

This is the example from the documentation:

&target=invert(Server.instance01.threads.busy)
