推荐答案

Grafana不会保存Prometheus中的数据.它查询Prometheus并显示UI.在这种情况下，您将不得不清除Prometheus数据.

Grafana does not saves data from Prometheus. It queries Prometheus and displays UI. In this case, you would have to look at purging Prometheus data.

普罗米修斯默认情况下有15天的保留期.但这可以通过-storage.local.retention标志进行调整以适合您的需求

Prometheus by default has a 15 day retention period. But this could be adjusted by the -storage.local.retention flag to suit your needs
