CACTI不能显示图像，rra下没有文件！权限，PATH，snmpwalk没问题

itxiaofei

装好了cacti，登录进去，发现不能显示图像
主要问题是rra下死活不能生成*.rrd文件
centos 4.4 ，rrdtool-1.0.50，mysql-4.1.20-1.RHEL4.1，cacti0.8.6i，cacti0.8.6j都试过

参考了http://bbs.chinaunix.net/viewthread.php?tid=648262

另外，1：除了监控linux本机，还建了一个host监控winxp，同样图像出不来。（winxp的snmp装了，snmpwalk同样没问题）
2：cacti0.8.6j解压后权限很奇怪，即使我chown root.root cacti-0.8.6j，chmod -R 777 cacti-0.8.6j也不能运行php，cp出来就可以

1. drwxr-xr-x  11 1000 users 4096 Jan 18 08:23 cacti-0.8.6j

请求大家帮忙。

jadedan

这个问题跟我的一模一样啊，为什么rrd文件出不来啊？

参考了http://bbs.chinaunix.ne ...

这可能是Cacti在WEB里面的设置.有一个fonts路径,你可能设置错啦.....

mcaser

我也是这样的问题，难道没有高手来给看看吗

mcaser

顶上去，这个问题我也是遇到了，其他都正常，就是没有文件生成，郁闷ing

xmbbx

今天也碰到这个问题，跟楼主的现象一样，已经解决了。

是cacti中全局配置（settings)中的
RRDTool Default Font Path
The path to the rrdtool default true type font for version 1.2 and above.
这一项没有填对。

benlin8p

RRDTool Default Font Path 設定是 /usr/share/rrdtool/fonts/DejaVuSansMono-Roman.ttf

但是...還是無法解決這個問題...我也有相同的狀況...舊的監控HOST一直都有在UPDATE資料,但想要新建HOST來監控

但是圖一直出不來

seaship

就是,有没有正解?我在win2003环境下也出现这样的情况

jerrywjl

去检查一下装包情况：下面这些包是否都装上了。
[root@localhost ~]# rpm -qa | grep php
php-cli-5.1.6-15.el5
php-ldap-5.1.6-15.el5
php-mbstring-5.1.6-15.el5

[root@localhost Server]# rpm -qa | grep snmp

net-snmp-utils-5.3.1-19.el5
net-snmp-devel-5.3.1-19.el5
php-snmp-5.1.6-15.el5

还有这些。如果都装上了，拿具体的配置过程和步骤来看看吧。
（说明一下，我是在RHEL5.1下做的，已经正常跑起来了。
我觉得系统的版本方面应该考虑用高版本的系统，RHEL4已经快被淘汰了。）

怪 了 我也是这个问题 怎么回事呢 :em11: :em11: :em11:
