munin 节点配置如下:
/etc/munin/plugin-conf.d/munin-node
...
[membyuser]
env.USERS user1 user2 user3 user4
...
munin-graph.log说:
[RRD ERROR] Unable to graph /var/cache/munin/www/myhost/host/membyuser-week.png : opening '/var/lib/munin/--g.rrd': No such file or directory

[RRD ERROR] Unable to graph /var/cache/munin/www/myhost/host/membyuser-year.png : opening '/var/lib/munin/--g.rrd': No such file or directory
我验证了目录存在且可写。这不是问题。
我发起了调试并说:

我不知道如何修复..
答案1
在屏幕截图中,我看到您使用的是 Munin v. 1.4.5。非常旧的版本。我使用的是 2.xx,并且没有 membyuser 插件。也许问题出在这个插件上,其定义不正确。我在 url 上看到了这个插件的一些版本: http://munin-monitoring.org/browser/munin-contrib/plugins/system/membyuser
但是我建议您升级 munin,因为旧版本有很多错误。
