Question

我已将munin配置为昨天从另一台服务器获取日志，并根据配置示例自定义配置Totals，用于两个服务器负载。

我使用rrdtool将rrd文件转换为xml并将其复制并将其转换回rrd以获取新计算机，以便了解它的历史记录

现在它工作得很好，但总计似乎已经停止生成一段时间了。我检查了日志，它说没有找到load2-day.png ...等文件。

我查了一下，他们在那里，chown和chmod匹配munin。

有关为什么它可能看不到文件的任何想法，一旦我看到它们如何强制完成图形再生，所以我不必等待5分钟才能找出它是否有效？

在此完成日志：

perl错误似乎不会影响任何内容，但我会很感激删除它的提示。

Answer 1

RRD ERROR行表示无法创建图形（png），因为RRD中的某些内容无法找到（或打开）某个文件。这个片段说它试图打开一条空白路径，然后失败。

opening '': No such file or directory

perl错误提到“未初始化的值$ filename”，这给出了RRD错误可能是问题的一部分。由于图表是从RRD文件生成的，因此可能的问题是系统无法找到您的RRD。因此，您需要检查有关指定RRD位置的所有内容都是有序的。

确认munin.conf中的dbdir指令是否正确
确认您的RRD存在于$ dbdir / domain / path
确认文件系统权限允许munin进程读取和写入所述路径
确认主机树（在munin.conf中）对于您遇到问题

关于触发图创建：munin服务器由cron驱动。您应该能够找到一个可以作为munin用户手动运行的cron作业，以便触发该过程。我过去使用的RPM在/etc/cron.d/munin

中有这个工作
