System Logs

The fluentd component does not collect the following system logs by default because they require the configuration of additional permissions for the $MAPR_USER.

Service name Parsing Method Description
kernlog Multi-line Kernel logs from /var/log/kern.log.
syslog Multi-line System logs from /var/log/syslog and /var/log/messages.
mysql_errors Multi-line MySQL errors from /var/log/mysql/error.log.
Note: To enable fluentd to read and parse these logs, see Configure Which Logs to Index and also perform the following:
  • On Ubuntu and RedHat/CentOS, add $MAPR_USER to admin group.
  • On RedHat/CentOS, change the ownership of the log file so that it is owned by both the root user and the admin group.
