The command

reports:

pm1       getLogConfig Failed - Error : 1

The log files have:

The error is hardcoded at
https://github.com/mariadb-corporation/mariadb-columnstore-engine/blob/columnstore-1.1.1/procmon/processmonitor.cpp#L3242

	string::size_type pos = fileName.find("syslog-ng",0);

	if (pos != string::npos) {

		// not supported

		log.writeLog(__LINE__, "ERROR: config file not support, " + fileName, LOG_TYPE_ERROR );

		return API_FAILURE;

I suggest to describe the limited support for syslog-ng at
https://mariadb.com/kb/en/library/preparing-for-columnstore-installation-11x/#system-logging-package
where the documentation says:

System Logging Package

MariaDB ColumnStore utilizes the System Logging applications for generating logs. So one of the below system logging applications should be install on all servers in the ColumnStore system:

syslog
rsyslog
syslog-ng
