First of all sorry for bothering anyone here for this question. It's a stupid one
sql_user password, so when I click on nagios QL, I get a message saying:
SELECT `category`,`name`,`value` FROM `tbl_settings`Error[3]: Access denied for user 'apache'@'localhost' (using password: NO)
I understand I need to change the MySQL password to the table it wants to view. But where can I change the sql_user pw in Nagios?
