VWLOG_RELOAD Command
The VWLOG_RELOAD command loads a specific Analytics Engine error log configuration file (vwlog.conf). The rules for log output specified in the file are used for all subsequent log events. If the log-configuration file is not parsed successfully, the current log rules remain active.
VWLOG_RELOAD can be used to change the error logging rules without the need to restart Analytics Engine. In particular, it can be used to increase the log level verbosity while debugging a process, and to otherwise decrease the log level for a more concise log file.
This command has the following format:
CALL X100( VWLOG_RELOAD ['''log_config_file''']);
where:
log_config_file
Specifies the name of a error log configuration file. It must be an absolute path and enclosed in triple quotes.
The file name (on keyword filename =) specified in the log_config_file must end with the string "vectorwise.log". This restriction on the log configuration file is a security precaution that only applies when using the VWLOG_RELOAD command.
Windows: The backslashes in the path name must be escaped, as shown in the example. 
Examples:
1. Read and parse a custom vwlog.conf file:
CALL X100(VWLOG_RELOAD '''C:\\Documents and Settings\\John\\My Documents\\my_vwlog.conf''');
2. Read and parse the default error log configuration file:
CALL X100(VWLOG_RELOAD);
