--storage.tsdb.retention.time=STORAGE.TSDB.RETENTION.TIME

--help 可以找到有四个针对 tsdb 存储相关的参数 --storage.tsdb.path 是 prometheus 采集的指标存放的路径--storage.tsdb.retention 已经被弃用了，官方让用 --storage.tsdb.retention.time 这个参数--storage.tsdb.retention.time 是指定 prometheus 采集的指标存放时长，如果 --storage.tsdb.retention.size 参数没有被配置，默认就是 15天--storage.tsdb.retention.size 是指定 prometheus 采集的指标达到最大存储大小，换算比例是 1:1024
