cacti不繪制資料圖

          Cacti不繪制監控圖

  剛上班，黃教主就叫：xxx，Cacti有問題啦！！！怎麼的啦？原來是Cacti不繪制監控圖了。

  The steps for save issue：

  1:出問題了，首先看相關服務日志：

  #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"

   發現有N行這樣的ERROR關于poller_output這張表的，後來查了一下，網上N多人說是此磁盤滿了（或其所在分區滿了），也沒心思查了，先看立刻解決問題的方法吧！！！

 2：登入cacti所在的資料庫

 #mysql -ucacti -pcacti cacti

 mysql> select count(*) from poller_output;

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

 出現大概如上的錯誤，查詢都沒法子，先把這張表的資料清空了。

 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，一切恢複正常了，稍等監控圖也會出來啦！！！

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》
