Parameters

Parameter

Description

cluster The cluster on which to run the command.
multi_cluster_info Specifies whether to display cluster information from multiple clusters.

Values: true or false. Default: false.

version Specifies whether to display the version. Values: true or false. Default: false.
zkconnect ZooKeeper Connect String
json Formats the output.

Output

A summary of information about the services, volumes, MapReduce applications, health, and utilization of the cluster.

Output Fields

Field

Description

timestamp

The time at which the dashboard info data was retrieved, expressed as a Unix epoch time.

timeofday The local time and date of the query.

status

The success status of the dashboard info command.

total

The number of clusters for which data was queried in the dashboard info command.

version

The MapR software version running on the cluster.

cluster

The following information about the cluster:

  • name — the cluster name
  • secure — where the cluster is secure or not. Value: true or false
  • ip — the IP address of the active CLDB
  • id — the cluster ID

  • Disk space — total and active in GB.
  • Compression — compressed and uncompressed data size
clusterReplication

The following cluster replication information:

  • bytesReceived
  • bytesSend
streamThroughput

The following stream throughput information:

  • bytesProduced
  • bytesConsumed

services

The number of active, stopped, failed, and total installed services on the cluster, for example:

  • CLDB
  • Fileserver
  • ResourceManager
  • NodeManager
  • hoststats
  • API server

yarn

The following mapreduce information:

  • Running applications
  • Queued applications
  • Number of NodeManagers
  • Total memory
  • Total VCores
  • Total disks
  • Used memory
  • Used VCores
  • Used disks
