Getting consumption spikes when using rate(scaph_host_energy_microjoules) on prometheus

[Louan-Robert]

Hello, I am using scaphandre in one of my projects, and I am encountering some problems.

When using scaph_host_energy_microjoules and applying prometheus rate() function to it, I am getting uge consumption spikes.

Note that this behavior only occures with scaph_host_energy_microjoules metric.

Do you have any idea on where these could come from ?

Thanks !

What does rate do? This may be normal, since scaph_host_energy_microjoules reports the energy consumed since the previous measurement. And the energy measurements occur at regular intervals.
