Grafana only displays last 2 months of data — full data exists in MinIO bucket

[Vidyasagar9390]

Description:

We're encountering an issue where Grafana only shows the last 2 months of data, even though all data since January 1 is stored in MinIO.

Details:

Data Storage: MinIO bucket

Visualization: Grafana only displays data from the last 2 months

Expected Behavior: Grafana should visualize all available data (from Jan 1 onwards)

Additional Info:

MinIO bucket checked: ✅ All data present from Jan 1

Grafana version: 11.3.1

Thanos version : 0.38.0

What we’ve tried:

Verified data in MinIO bucket directly

Checked Grafana dashboard time range settings

Request:

Please help identify why Grafana isn’t displaying the full range of data available in MinIO. Any guidance from thanos would be appreciate, is there any problem with thanos query , store
