Trying to get mysql plugin working but, no mysql information shown on checkmk site

Output of mysql plugin (/usr/lib/check_mk_agent/plugins/mk_mysql) on client side is showing mysql databases and detail.
Also output of check_mk_agent showing mysql detail informations
cmk-agent-ctl dump showing only mysql service informations, none of mysql database details

Any help would be greatly apreciate
Regards,
Vincent
