Unable to Retrieve CPU Usage Metrics in Grafana for Periods Ranging from 5 Minutes to 12 Hours

[RiccardoMengarelli]

Describe the bug a clear and concise description of what the bug is.

We are encountering an issue with Grafana where we are unable to retrieve CPU usage metrics for periods ranging from 5 minutes to 12 hours. When we attempt to query Grafana for CPU consumption data within this time frame, the system returns no results; there are no data points or statistics displayed. However, when querying for the same metrics over the past 24 hours, Grafana successfully displays all relevant data. This indicates that the data exists within the system but is not being visualized for shorter time periods.

Here last 24 hours

here last 12 hours

Grafana Version: Grafana Loki 2.8.2

Any assistance or guidance on resolving this issue would be greatly appreciated. Thank you.
