How can I graph the percentage change between an earlier value and a current value?

If you want to visualize how a metric’s values have changed in comparison to an earlier time period, do so by leveraging the Timeshift functions. You can capture a metric’s value from an hour, day, week, or month before.

To calculate this, you can create a query such as this:

((current_value - old_value) / old_value) * 100

Here’s an example where you can see the percentage change of a system metric from one day ago to the present:
