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.

If nodes in the cluster run two filesystem instances, Fluentd only reads and parses logs from primary fileserver instance. Therefore, logs from the secondary fileserver instance will not be indexed by Elasticsearch.
mfs Multi-line Data Fabric filesystem logs from $MAPR_HOME/logs/mfs.log-3.
NOTE
