Mariadb default logs location & --log-error

I am using mariadb and I to investigate some issue I wanted to check the logs. To my surprise, log file is not generated for mariadb. I suspect this cannot be the case so I am doubting my search skills. MariaDB [(none)]> show variables like 'log_error' -> ; +---------------+-------+ | Variable_name | Value | +---------------+-------+ | log_error | | +---------------+-------+ 1 row in set (0.00 sec) I have added the entry in my.cnf still above field is coming to be empty. [root@cslcodev11-oem ~]# cat /etc/my.cnf [mysqld] !includedir /etc/mysqld/conf.d datadir=/mnt/mgmt/var/lib/mysql socket=/var/lib/mysql/mysql.sock tmpdir=/mnt/mgmt/var/lib/mysql_tmp user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 ### TRT-3229 ##### sync_binlog=1 innodb_flush_method=O_DIRECT innodb_support_xa = 1 myisam_repair_threads = 2 myisam_recover_options = FORCE ################### innodb_file_per_table=1 innodb_log_buffer_size = 8M table_open_cache=256 max_heap_table_size=256M ### TRT-4685 ### max_connections=500 ################ innodb_log_file_size = 512M [mysqld_safe] log-error=/var/log/mariadb/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [root@cslcodev11-oem ~]# So, I want to know do we have any default location where these logs are getting generated, if the path cannot be read from config files. ## Update: ## After some investigation, I found this information, *Reference: https://mariadb.com/kb/en/mariadb/error-log/* ---------- **Activating the Error Log** The error log is active by default. The log-error=filename option determines where the output will be written. If no file name is specified, the log will be written to host-name.err. If no absolute path is specified, the file will be written to the data directory (determined by the value of the datadir system variable). *On Unix systems, if the --log-error option is not used, the errors are written to stderr (usually, the command line).* *On Windows, if the --console option is specified, and --log-error is not used, the errors are written to the console. If --log-error is present, --console is ignored.* So now I understand that due to some reason the configuration **log_error** in my.cnf is not considered. So as per the suggestion, on Unix system, if --log-error is not used, logs are redirected to stdout. ---------- BUT, I am starting the service using service mysqld start command so I want to know what all options are used by default when we start the service using service mysql start? ESP, is --log-error used?
