key: the path name of the client private key file. + - cert: the path name of the client public key certificate file. + - ca: the path name of the Certificate Authority (CA) certificate file. This option, if used, must specify the + same certificate used by the server. + - capath: the path name of the directory that contains trusted SSL CA certificate files. + - cipher: the list of permitted ciphers for SSL encryption. + +Here is an example for 3 servers: + +```yaml +update_every : 10 +priority : 90100 + +local: + 'my.cnf' : '/etc/mysql/my.cnf' + priority : 90000 + +local_2: + user : 'root' + pass : 'blablablabla' + socket : '/var/run/mysqld/mysqld.sock' + update_every : 1 + +remote: + user : 'admin' + pass : 'bla' + host : 'example.org' + port : 9000 +``` + +If no configuration is given, the module will attempt to connect to MySQL server via a unix socket at +`/var/run/mysqld/mysqld.sock` without password and with username `root` or `netdata` (you granted permissions for `netdata` user in the Requirements section of this document). + +`userstats` graph works only if you enable the plugin in MariaDB server and set proper MySQL privileges (SUPER or +PROCESS).
