Hello, can you provide more details? For example, deployment and configuration, greptime version.
Is it currently written to greptime through prometheus remote write? You can check the prometheus and greptime log to see if there are any errors.

Try to improve the prometheus remote write queue configuration: https://prometheus.io/docs/prometheus/latest/configuration/configuration/

          queue_config:
            capacity: 10000
            minShards: 1
            maxShards: 50
            maxSamplesPerSend: 20000
            batchSendDeadline: 20s
            minBackoff: 1s
            maxBackoff: 8s

Can you configure greptime metrics here: https://github.com/GreptimeTeam/greptimedb/tree/main/grafana/dashboards/metrics

In addition, these graph are different time in prometheus and greptime(start time -> end time).

Maybe caused by #5405
We can verify this by adding a Transform in the Grafana panel settings to sort data by Time manually.
