Error Log:

Poller[0] ERROR: SQL Assoc Failed!, Error:’1017′, SQL:”select  poller_output.output,  poller_output.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″


Check your cacti database. This may be because of any table corruption.

While checking we found  poller_output table was corruption.

Solution:

Try repairing the corrupted table, if it was not successfully.

Then try Truncated that particular table through phpmyadmin and rebuild the poller cache through Cache Admin->System Utilities.

TRUNCATE `poller_output` ;
Your SQL query has been executed successfully

Due to low disk space in the database server, the table poller_output was corrupted in our case.
