【问题描述】:
我用我的 raspi 构建了 NTP 服务器,然后我使用 MRTG 来监控 OFFSET 和 JITTER,它工作正常。 我之前的偏移值只是 +1000,因为可以显示负值。 现在我想更改可以绘制负值的图表,所以我决定将 MRTG 与 RRDTool 一起使用并按照指南 https://weberblog.net/basic-ntp-server-monitoring/?fbclid=IwAR3iV_rdwQK95axV8JWSmtBub9bhHtGbn9SGtLHSfSotsRXEVkO8YLuqZFM 进行操作,但它不起作用。 这是我的 mrtg.cfg

你真的应该使用 0.00001 的系数,然后让 mrtg/routers 负责显示正确的单位
