使用API以5s间隔时间push数据,用于实时观察接口调用情况,发现:

  1. dashboard 分别率最低30s
  2. 数据延时,延时将近5分钟

另外: 可否提供类似Google charts开源图表那种 鼠标移动上去时,显示标尺和每条线的数值,现在必须点到对应线上确定时间点才显示,线多的时候很很难看清楚。

  1. 数据延时,延时将近5分钟

这个问题已经大概知道了,ajax请求上传本地end时间,两机器时间差造成读取延时,而且end为本机时间-60s(应该是考虑1分钟一个点吧); 考虑使用将begin~end 改成 最近xx 时间 就没有时钟不一致的问题了吧。

RRD 1分钟一个点,实际图却是30s一个点,我修改graph RRD 采集到5s 一次但不生效呢?
