MapR Core Logs

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

Service Name Parsing Method Description
adminuiapp Multi-line MCS logs from $MAPR_HOME/logs/adminuiapp.log.
cldb Multi-line CLDB server logs from $MAPR_HOME/logs/cldb.log.

mfs Multi-line MapR-FS logs from $MAPR_HOME/logs/mfs.log-3.
Note: 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.
