SQL error

[amohamed]

Hello people,

Cacti was running smoothly till I got the below error:

FATAL: Cannot connect to MySQL server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'

then i did a restart to the server hosting cacti, and it became reachable, but no new data is being graphed, I did snmpget to the devices from the windows cmd and it responded correctly.

Any help please, i think I need to verify the SQL database health, but don't know how to.

Checked the cacti technical support page?
checked the cacti log file for errors?
