1.cacti 安装时区出错

Warning: date(): It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone ‘UTC’ for now, but please set date.timezone to select your timezone. in /var/www/localhost/htdocs/cacti/lib/functions.php on line 486
02/11/2014 06:25:10 AM – SYSTEM STATS: Time:0.1238 Method:cmd.php Processes:1 Threads:N/A Hosts:2 HostsPerProcess:2 DataSources:1 RRDsProcessed:1
OK u:0.00 s:0.00 r:0.02
解决如下

vim /etc/php/cli-php5.5/php.ini

date.timezone = Asia/Shanghai

vim /etc/php/apache2-php5.5/php.ini

date.timezone = Asia/Shanghai

2. 安装 cacti-spine emerge -avq cacti-spine

登陆 cacti 后设置

Poller Type

The poller type to use. This setting will take effect at next polling interval. spine (默认是 cmd.php)

3. 收集的时候出现

POLLER: Poller[0] Maximum runtime of 300 seconds exceeded. Exiting
http://chinaapp.sinaapp.com/thread-tag/poller-poller0-maximum-runtime-of-298-seconds-exceeded-exiting
报错的原因是因为：cacti php
crontab 里面默认执行时间超过了 300 秒，而 cacti 默认是 5 分钟就是 300 秒去获取一次数据，所以导致有些服务器的数据没有获取。
所以想到了增大 spine 的进程和线程数。cacti->Console->setting->Poller->：
修改 cacti setting 的 poller 设置. settting–>poller: Maximum Concurrent Poller
Processes 把 1 改成 4 Maximum Threads per Process 把 1 改成 2 Number of PHP Script
Servers 把 1 改成 6 即可
4.crontab -l

*/1 * * * * /usr/bin/php /var/www/localhost/htdocs/cacti/poller.php –force &>/dev/null

5.Settings–poller

Poller Interval
The polling interval in use. This setting will effect how often rrd’s are checked and updated. NOTE: If you change this value, you must re-populate the poller cache. Failure to do so, may result in lost data. every minute

Cron Interval
The cron interval in use. You need to set this setting to the interval that your cron or scheduled task is currently running. every minute

不能正常出图，注意查看日志 Console -> Utilities -> View Cacti Log File
