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
