MySql Slave status

We are running a mysql sensor on a linux db server to track our slave status.

We are setting up the sensor on a upgraded db server and are receiving an error : "Authentication method 'mysql_clear_password' not supported by any of the available plugins."

Does anyone know a way to resolve this error?

Thanks -Evan

Hello EA,

PRTG uses small executable for this sensor, which also has got a debug interface. Please go to your PRTG installation directory and open the "Sensor System" subfolder. (Usually C:\Program Files (x86)\PRTG Network Monitor\Sensor System)

Now start the SQLv2.exe and a window will show that offers the same settings as the sensor. It is less comfortable and does not do any checks on the values you enter, please be careful. Enter your server information and the SQL query.

You get a result table or an authentication error again? In the latter case, please try to use alternative authentication option to the database.

Hi EA,

In this case, I suspect wrong credentials or a missing setting in at the database server. Please validate whether the credentials are working. In addition, please check whether the Probe is allowed to access the database (Access host list)
