Traccar connection

First of all, thank you very much for the traccar service. How do I know if my database connection is correct? My connection settings are as follows:

<entry key="config.default">./conf/default.xml</entry>
 <entry key='web.port'>80</entry>
   <entry key='geocoder.enable'>false</entry>
   <entry key='database.driver'>com.mysql.jdbc.Driver</entry>
   <entry key='database.url'>jdbc:mysql://localhost/nthiz?allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;characterEncoding=UTF-8&amp;sessionVariables=sql_mode=''</entry>
   <entry key='database.user'>root</entry>
   <entry key='database.password'>root</entry>
   <entry key='server.timeout'>120</entry>
