Any ideas how i can fix that? 有什么想法我可以解决吗？ A lot of thanx for any help! 很多thanx可以提供任何帮助！

Usually, gaps in graphs are a result from the munin server not being able to contact the node. 通常，图形中的间隙是由于munin服务器无法联系该节点而导致的。 This can be because the server is too busy (too many nodes to process), the node is too busy or unreachable, or the network is down. 这可能是因为服务器太忙（要处理的节点太多），节点太忙或无法访问或网络已关闭。

In this case, there are regular 15 minute intervals at suspiciously accurate intervals. 在这种情况下，也有怀疑在准确的时间间隔定期15分钟的间隔。 This usually points to a scheduled job of some sort, which causes munin to fail at these times: 这通常指向某种计划的作业，这会导致munin在以下时间失败：

6:55 to 7:10 6:55至7:10
7:55 to 8:15 7:55至8:15
8:55 to 9:10 8:55至9:10
9:55 to 10:10 9:55至10:10
10:55 to 11:10 10:55至11:10
11:55 to 12:10 11:55至12:10

I'd start my investigation with monitoring CPU, Disk and Network activity manually on both the server and the node simultaneously between 10:55 and 11:10 (using top and ping will give you a ballpark idea) 我开始我与监测CPU，磁盘和网络手动活动服务器，并同时与10:55之间11:10的节点上，调查（使用top和ping会给你一个大概的想法）
