6.2 Administration
This section describes how to manage the nodes and services that make up a cluster.
Administering Tables
Administration of the HPE Ezmeral Data Fabric Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the HPE Ezmeral Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Ezmeral Data Fabric Database administration is associated with tables, columns and column families, and table regions.
Managing Table Replication
This section contains topics about setting up table replication and administering existing replicas.
Viewing Active Table Replication Alarms
Describes how to view active table replication alarms using the Control System and the CLI.

Viewing Active Table Replication Alarms

Describes how to view active table replication alarms using the Control System and the CLI.

You can view table replication alarms using the Control System, the log files, and the CLI.

Viewing Active Table Alarms in the Control System

Log in to the Control System and click Data > Tables to view table replication alarms in the Active Alarms pane.

You can:

View information related to the alarm.
Dismiss an alarm.
Mute an alarm.

See Table-Replication Alarms for more information on the table alarms.

Retrieving Active Table Replication Alarms Using the CLI or REST API

Alarms for replication are issued per volume rather than per source table. To retrieve table replication alarms, run the following command:

maprcli alarm list -cluster <cluster name> -type volume

For complete reference information, see alarm list.

Viewing Table Replication Alarms in the Log Files

The log files mfs.log-5 and cldb.log display these alarms. These files are located in the /opt/mapr/logs directory.
