Grafana中的多时间序列运算 [英] Multi-timeseries operations in Grafana

问题描述

如何减去 Grafana 中的两个时间序列?或将两者加在一起，一一分开，依此类推...?我在网上发现有关在时间序列之间进行区别的模糊提示，但实际上并没有告诉我如何去做.我正在将Grafana v2.0.2与Influxdb v0.8一起使用，并且已经使用了足够的图形控件来发现类似我可以应用的difference运算符之类的东西，但是我不知道如何使用它.我试图找到有关此问题的文档，但是我能找到的最接近的几乎没有声音.关于此主题，并且看起来也有些过时，因为自从截取这些屏幕截图以来，界面已发生更改.

How do I subtract two timeseries in Grafana? Or add two together, divide one by another, etc...? I have found vague hints online about taking differences between timeseries, but nothing that actually tells me how to do so. I'm using Grafana v2.0.2 with Influxdb v0.8 and have played around with the graph controls enough to discover things like the difference operator I can apply, but I have no idea how to use it. I've attempted to find documentation on this, but the closest I can find is pretty much silent on this topic, and also looks to be slightly out of date, as the interface has changed since those screenshots were taken.

谢谢！

推荐答案

此功能已添加为格拉法纳(Grafana)第177期:

设置两个系列，单击眼睛图标将其隐藏，然后将第三个与前面的部分相除.

Setup two series, click the eye icon to hide them and put a third with the division of the preceding ones.

这仅在Graphite中有效(我希望它也能严重流入)

This is only working in Graphite (I'd like it to work on influx badly also)
