Grafana time series future points displaying

Monitoring and Observability Grafana
1

Hi all, I’m testing an observability stack that consists of Grafana for visualization, Mimir to store metrics, Alloy to scrape, and cAdvisor to expose metrics. All of them are running in containers with docker compose.

I’m seeing about 5 minutes of future points in Grafana’s time series (e.g. see screenshot of container_cpu_usage_seconds_total{} with a time window from=now-6m to=now+6m). The data appears to just be a flat continuation of the most recent point, each point updates with the actual data as the minute rolls around. Is this a normal behavior? Can I turn off this projection? How?

Hmm, taking a look at your time range picker, did you enter that value? Its set to go from 6 mins in the past to 6 in the future

3

yes, I extended the window into the future to see when the data points ended

Ah got it - yeah I’m not sure why it would project future data without something set up to do that. I’ll have to step back and let someone else answer that one

Looks like Prometheus staleness of 5 minutes which somehow is visualized for future?

Or maybe Strange min step Intervall which is to big
