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 . |

mfs_maprdb | Multi-line | HPE Ezmeral Data Fabric Database logs from $MAPR_HOME/logs/mfs.log-5 .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. |
mfs | Multi-line | Data Fabric filesystem
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. |
