cacti不能出图像！！

bruce_lrd

查看rra 和log 权限都是cacti 属组的，查看Graph Management:
ERROR: opening '/var/www/html/cacti/rra/www_test.com_mem_buffers_37.rrd': No such file or directory
把我的snmpd.conf发上来：
   com2sec notConfigUser   10.11.49.200       public
group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser

syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat


请大家帮我看看！！

rra 权限问题。 snmp配置问题，snmp配置可以用snmpwalk去检测下。防火墙是否阻止snmp？

我的也是，有几台机器不能出图，rrdtool 下全显示nan 看log里有sql的报错，repair_database也不行。
更奇怪的是就是只有几天机器不可以，其它的都行。
而且那几个rra文件用rrdtool update看的更新时间，居然是今天下午，我的系统时间是正确时间。

权限rra我给了777，LOG也给了777，奇怪的是rra/里没有东西，log里的cacti.log也没有东西
我应用在内网，所以没有开防火墙的，而且是获取本机上的SNMP信息。
我用/usr/bin/php /var/www/html/cacti/poller.php 手动没有任何数据，不知道是哪里出错了！！！

liang3391

snmp没有被防火墙阻止吧。那就是rra 的权限问题了。需要用cacti 的用户来运行。还有cacti web界面setting里的配置要正确。

bruce_lrd

那么应该如何配置呢？setting我看过了应该没问题的！！rra应该如何？

大侠们别忽略俺的问题啊~~~

一刀砍死

你在devices添加主机时，snmp信息正常吗？

哥们的问题  你先手动执行几次 poller.php 看看。可能和crontab里设置有关系。

david6102 哥们的描述 可能和mysql里的设置有关系。贴出来具体点。也可能是crontab设置问题
