Change resolution and intervals?

[Spenhouet]

The documentation states:

Resolution is a distance between data points on your graphs. E.g.

raw - the same as scrape interval at the moment of data ingestion
5 minutes - data point is every 5 minutes
1 hour - data point is every 1h
Compactor downsampling is done in two passes:

All raw resolution metrics that are older than 40 hours are downsampled at a 5m resolution
All 5m resolution metrics older than 10 days are downsampled at a 1h resolution

I couldn't find a clear statement on this, but I gathered that both, the 5min/1h and the 40h/10d are hardcoded fixed configurations.

Can't I configure these? Also can't I introduce additional intervals? If yes, why?

Hey @Spenhouet! I'm here to help you with any bugs, questions, or contributions you have. Let's dive into this together!

The downsampling intervals in Thanos (5 minutes and 1 hour) are indeed fixed and cannot be configured. However, you can customize the retention periods for these intervals using specific flags:

• --retention.resolution-raw: Sets how long to retain raw samples.
• --retention.resolution-5m: Sets how long to retain 5-minute resolution samples.
• --retention.resolution-1h: Sets how long to retain 1-hour resolution samples.

These flags allow you to control how long data is kept at each resolution, but they do not allow you to change the downsampling intervals themselves or introduce additional intervals ^[1].
