Root cause & Resolution :
The table “poller_output” in cacti
database has corrupted. I've logged into the database and try to
repair the table. Issue below commands.
Mysql > use cacti;
mysql > truncate table poller_ouput;
Then restarted the services apache and
mysql. After a while graph is displayed and draw accordingly.
