    - Managing Alarms
      - Viewing the List of Alarms
        Specifies how to view the list of alarms raised, using either the Control System or the CLI.
      - Configuring Alarm Settings
        Set the severity and notifications for each alarm using either the Control System or the CLI.
      - Configuring the Alarm Threshold Using the CLI
        You can configure the alarm threshold for certain alarms. For the alarms that support threshold configuration, this topic describes the command to run to set the threshold.
      - Viewing Alarm Information
        Describes how to view alarm information using the Control System.
      - Dismissing an Alarm
        Describes how to dismiss an alarm, either manually or automatically, using either the Control System or the CLI.
      - Muting and Unmuting Alarms
        Describes how to mute and unmute alarms using either the Control System or the CLI.
    - Working with Multiple Instances of the File System
      The Multi-MapR File System feature allows multiple instances of the file server to run on a single node in a single process.
    - Converting a Cluster from Root to Non-Root User from the Command-Line
      Provides a synopsis of changing the running user from root to a non-root user on a cluster.
    - Starting Up a Cluster
      Lists the steps to start a cluster that was previously shut down.
    - Shutting Down a Cluster
      Lists the considerations to note and the procedure to shutdown a cluster.

  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of MapR clusters.
- Administering Files and Directories
- Administering Tables
  Administration of the MapR Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the MapR Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. MapR Database administration is associated with tables, columns and column families, and table regions.
- Administering Streams
- Administering MapR Gateways
  A MapR gateway mediates one-way communication between a source MapR cluster and a destination cluster. You can replicate MapR Database tables (binary and JSON) and MapR Event Store For Apache Kafka streams. MapR gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.
- Administering Services
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring Security
  Describes how to configure security and manage secure clusters.
- Managing Secure Clusters
  Provides procedures that will enable you to use MapR clusters securely.
- Administering the MapR Data Access Gateway
  The MapR Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the MapR cluster. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.
- Planning for High Availability
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Troubleshooting Cluster Administration

Muting and Unmuting Alarms

Describes how to mute and unmute alarms using either the Control System or the CLI.

About this task

You can mute (silence) one or more (non-critical) alarms for a specific period of time using either the Control System or the CLI. The alarm will be silenced for the duration of the mute period and CLDB will raise the alarm again after the mute period only if the conditions for raising the alarm instance again are met.

Muting Alarm(s) Using the Control System

About this task

The Mute action is available in all the Active Alarms pane and in the Alarms Summary page. To mute alarm(s):

Procedure

Click Mute to display the Mute Alarms dialog.
Verify the alarm(s) to mute.
Select the period of time (1 hour, 6 hours, or 24 hours) to mute the alarm for from the Mute Alarms for drop-down list.
Click Mute Alarms to mute the alarm(s).
The alarm will be raised again if the associated issue is not resolved within the specified period of time.

Muting Alarm(s) Using the CLI

About this task

The basic command to mute an alarm is:

maprcli alarm mute -alarm <alarm name>[:<entity>]:<mute_period>

For complete reference, see alarm mute.

Unmuting Alarm(s) Using the CLI

About this task

The basic command to mute an alarm is:

maprcli alarm unmute
