cacti 有圖沒日誌,附配置文件和日誌,麻煩高手看看
cacti 版本0.8.7e ，裝在centos 5.3上，現在創建一個device后，手動執行/usr/bin/php /var/www/html/cacti/poller.php 在rra下有文件產生，圖片有，但是都顯示nan,沒有數據
我測試結果如下：
1.許可權應該沒問題：

省略一部分。。。
5.snmpd.conf 修改過的地方
####
# First, map the community name "public" into a "security name"
# sec.name source community
#com2sec notConfigUser 127.0.0.1 public
com2sec notConfigUser default public
####
# Second, map the security name into a group name:
# groupName securityModel securityName
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
####
# Third, create a view for us to let the group have rights to:
# Make at least snmpwalk -v 1 localhost -c public system fast again.
# name incl/excl subtree mask(optional)
#view systemview included .1
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
####
# Finally, grant the group read-only access to the systemview view.
# group context sec.model sec.level prefix read write notif
access notConfigGroup "" any noauth exact all none none
# -----------------------------------------------------------------------------
其他地方都沒做修改，所以沒貼。
我一般都用root執行 /usr/bin/php /var/www/html/cacti/poller.php ，然後到rra下將所有者改為cactiuser，這個有問題嗎？我用cactiuser執行的時候提示：

許可權問題。目錄rra log 777許可權和目錄用戶root：cactiuser許可權。
[ 本帖最後由 liang3391 於 2009-7-14 21:38 編輯 ]
《解決方案》
許可權我已經改過來了。
我現在用cactiuser 執行 /usr/bin/php /var/www/html/cacti/poller.php 好像提示許可權有問題：

到這個session目錄下去看了，許可權都是root
《解決方案》
把rra下面文件許可權改為777就可以了，謝謝。
《解決方案》
我配置監控遠程主機的時候，在devices--status 顯示unknown是什麼原因？沒有圖rra下頁沒有文件
