Data Fabric Core Logs

The fluentd component reads and parses the following Data Fabric Core log files on each node in the cluster.

Service Name Parsing Method Description
adminuiapp Multi-line Control System logs from /opt/mapr/apiserver/logs/apiserver.log.
cldb Multi-line CLDB server logs from $MAPR_HOME/logs/cldb.log.
