Cacti不绘制监控图

  刚上班，黄教主就叫：xxx，Cacti有问题啦！！！怎么的啦？原来是Cacti不绘制监控图了。

  The steps for save issue：

  1:出问题了，首先看相关服务日志：

  #cd /var/www/html/cacti/log

  #tail -fn100 cacti.log

09/18/2012 10:10:08 AM - CMDPHP: Poller[0] ERROR: SQL Assoc Failed!, Error:'1017', SQL:"select  poller_output.output,  poller_output.time,  UNIX_TIMESTAMP(poller_output.time) as unix_time,  poller_output.local_data_id,  poller_item.rrd_path,  poller_item.rrd_name,  poller_item.rrd_num  from (poller_output,poller_item)  where (poller_output.local_data_id=poller_item.local_data_id and poller_output.rrd_name=poller_item.rrd_name)  LIMIT 10000"

09/18/2012 10:10:08 AM - CMDPHP: Poller[0] ERROR: SQL Assoc Failed!, Error:'1017', SQL:"select  poller_output.output,  poller_output.time,  UNIX_TIMESTAMP(poller_output.time) as unix_time,  poller_output.local_data_id,  poller_item.rrd_path,  poller_item.rrd_name,  poller_item.rrd_num  from (poller_output,poller_item)  where (poller_output.local_data_id=poller_item.local_data_id and poller_output.rrd_name=poller_item.rrd_name)  LIMIT 10000"

   发现有N行这样的ERROR关于poller_output这张表的，后来查了一下，网上N多人说是此磁盘满了（或其所在分区满了），也没心思查了，先看立刻解决问题的方法吧！！！

 2：登录cacti所在的数据库

 #mysql -ucacti -pcacti cacti

 mysql> select count(*) from poller_output;

  ERROR 1017 (HY000): Can't find file: 'poller_output' (errno: 2)

 出现大概如上的错误，查询都没法子，先把这张表的数据清空了。

 mysql> truncate table poller_output;

  Query OK, 0 rows affected (0.02 sec)

 mysql> select count(*) from poller_output; 

+----------+
| count(*) |
+----------+
| 0 |
+----------+
1 row in set (0.00 sec)

 OK，一切恢复正常了，稍等监控图也会出来啦！！！

看下cacti的日志：

 09/18/2012 11:00:05 AM - PHPSVR: Poller[0] WARNING: Script Server terminated with signal 'SIGSEGV' in file:'ss_host_disk.php', function:'ss_host_disk', params:'172.31.10.11 23 2:161:500:1:10:51auto:::::: get total 38'

一切正常了》
