dashboard info

Displays a summary of information about the cluster.

Syntax

CLI

maprcli dashboard info
    [ -cluster <cluster name> ]
    [ -multi_cluster_info true|false]
    [ -version true|false ]
    [ -zkconnect <ZooKeeper connect string> ] 
    -json

NOTE: The -json option is required.

REST

Request Type	GET
Request URL	`http[s]://<host>:<port>/rest/dashboard/info[?<parameters>]`

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 `nodesUsed` — number of nodes in the cluster `totalNodesAllowed` — number of allowed nodes
volumes	The number and size (in GB) of volumes that are: Mounted Unmounted
utilization	The following utilization information: CPU — utilization, total and active. CPU utilization % is calculated as (100% - idle%) on each node and then averaged across all nodes where hoststats is running. Memory — total and active in mB. 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
