munin - 可以更改 munin 图的更新间隔吗？

Question

我想每两分钟后 munin 绘制图形以增加粒度。有一些链接指出它以某种方式可能与 munin 2.0 一起使用，知道如何吗？

Answer 1

我没试过，但是this question in the FAQ建议你不能:

Munin runs at an interval of every five minutes (*/5) on debian systems by default. Is it possible to change this interval to an arbitrary value?

Just edit /etc/cron.d/munin.

However, this won't change Munin's (or rather RRD's) granularity; all RRD files are constructed to create 5 minutes averages, and no matter how often you update the RRD files the output won't be (much) different. Changing this (default) behaviour has been proposed in Ticket #5.

但是，如果您查看 ticket #5 ，最后一个帖子(关闭它)是:

current trunk fully supports custom update_rate, and increase resolution of .rrd files accordingly.

因此，如果您使用的是相当新版本的 munin，则可能值得一试。
