Munin：丢失的图表有可能恢复吗？
我不太熟悉 munin 的工作原理，所以如果这是显而易见的，我深表歉意。
我现在已经在我的几个项目中使用 munin，并且已经遇到过两次这种情况，我将丢失从过去的事件生成的所有 munin 图表。 这件事今天下午才发生在我身上。 现在，我只有今天下午以来所有系统事件的跟踪记录。
这些图表可以恢复吗？ 是否有数据存储在用于生成这些图表的地方？
如果无法恢复，我想知道是什么可能导致这种情况发生。 诚然，每次发生这种情况时，我都会弄乱我的 munin 配置设置。 对于这种情况，我添加了由 munin 记录的新服务器...我不知道这样做会如何导致 munin 丢失其他服务器上的所有数据。
谢谢。
I'm not extremely familiar with how munin works, so I apologize if this is obvious.
I've been using munin for a couple of my projects now and I've run into this twice where I will lose all my munin graphs that were generated from past events. This just happened to me this afternoon. Now, I only have a track record of all system events since this afternoon.
Are these graphs recoverable? Is there data stored somewhere thats used to generate these graphs?
If its unrecoverable, I would like to know what could possibly have caused this to occur. Granted, each time this has happened, I was messing w/ my munin config settings. For this case, I was adding new servers to be logged by munin...I dont see how doing that would cause munin to lose all data on my other servers.
Thanks.

数据是从 .rrd 数据库生成的，该数据库在“munin-update”期间更新（通常从“munin-cron”调用）。 您可以在 munin.conf 中“dbdir”指定的目录（我的网站上的 /var/db/munin）中找到这些文件。 如果您的图表仅显示今天下午以来的事件，我的猜测是 .rrd 文件已被删除/重新创建/损坏。 您应该能够从备份中恢复它们，然后调用“munin-graph”和“munin-html”。 请参阅这些命令各自的手册页。
the data is generated from .rrd databases which are updated during 'munin-update' (usually called from 'munin-cron'). You can find those files in the directory specified by 'dbdir' in munin.conf (/var/db/munin on my site). If your graphs only show events since this afternoon, my guess is that the .rrd files got deleted/recreated/corrupted. You should be able to restore them from backup and then call 'munin-graph' and 'munin-html'. See the respective man-pages for those commands.
