In
Plesk 11.5,
InnoDB Database size is shown incorrectly if "innodb_file_per_table" option is enabled in my.cnf.This is bug found in Parallels Plesk 11.5. In order to resolve the issue, we need to patch the /usr/local/psa/admin/sbin/statistics_collector script with the patch provided by parallels.
You can get this from the link:
http://kb.parallels.com/Attachments/kcs-28596/statistics_collector 1. Backup /usr/local/psa/admin/sbin/statistics_collector
# cp /usr/local/psa/admin/sbin/statistics_collector /usr/local/psa/admin/sbin/statistics_collector.bak
2. Replace it with attachment and set correct permissions:
# chown root:root /usr/local/psa/admin/sbin/statistics_collector
# chmod 750 /usr/local/psa/admin/sbin/statistics_collector
That's it.
