Parameters

Parameter	Description
cluster	The cluster on which to run the command.

version	Specifies whether to display the version. Values: true/false. Default: false
zkconnect	ZooKeeper Connect String

Output

A summary of information about the services, volumes, mapreduce jobs, 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: false or true 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 File server Job tracker Task tracker HB master HB region server
mapreduce	The following mapreduce information: Queue time Running jobs Queued jobs Running tasks Blacklisted jobs
maintenance	The following information about system health: Failed disk nodes Cluster alarms Node alarms Versions
