Moviri Integrator for TrueSight Capacity Optimization - Ambari

“Moviri Integrator for TrueSight Capacity Optimization – Ambari” allows extracting data from Hadoop deployments through the open-source component Ambari. Relevant capacity metrics are loaded into BMC TrueSight Capacity Optimization, which provides advanced analytics over the extracted data in the form of an interactive dashboard, the Hadoop View.

The integration supports the extraction of both performance and configuration data across different Hadoop components and can be configured via parameters that allow entity filtering and many other settings. Furthermore the connector is able to replicate relationships and logical dependencies among entities such as clusters, resource pools, services and nodes.

The documentation is targeted at BMC TrueSight Capacity Optimization administrators, in charge of configuring and monitoring the integration between BMC TrueSight Capacity Optimization and Ambari.

Requirements

Supported versions of data source software

  • Supported Hadoop distribution is Hortonworks Data Platform (HDP): version 2.2 and 2.51
  • Supported Ambari: version 1.6 to 2.41, REST API v1

1 - HDP version 2.5 and Ambari version 2.5 are supported only if you apply the Feature Pack 1 (10.7.01) of the TrueSight Capacity Optimization 10.7.

 

The integration, though not officially supported, is expected to work on custom deployments of Hadoop components that leverage Ambari as their management and monitoring service.

Supported configurations of data source software

Moviri – Ambari Extractor requires Ambari is continuously and correctly monitoring the various entities supported by the integration, full list available below. Any lack in meeting this requirement will cause lask in data coverage.

Installation

Downloading the additional package

Network View is made available in the form of an additional component, which you may download from BMC electronic distribution site (EPD) or retrieve from your content media.

Installing the additional package

 To install the connector in the form of a TrueSight Capacity Optimization additional package, refer to Performing system maintenance tasks instructions.

 

Datasource Check and Configuration

Preparing to connect to the data source software

The connector included in "Moviri Integrator for TrueSight Capacity Optimization – Ambari" use the Ambari REST API v1 to communicate with Ambari. This is always enabled and no additional configuration is required.
Please note that only GET method is used by the connector, preventing any accidental change to the environments.
The connector requires a regular Cloudera Manager user (admin privileges not required) with read-only permissions on all the clusters that should be accessed.

Connector configuration attributes

The following table shows specific properties of the connector, all the other generic properties are documented here.

The following image shows the list of options in the ETL configuration menu, with also the advanced entries.

Supported entities

The following entities are supported:

  • Hadoop Cluster
  • Hadoop Resource Pool
  • Hadoop Node

In addition to standard system performance metrics, data related to the following Hadoop specific services is gathered:

  • HDFS
  • SPARK
  • YARN
  • HBASE

Hierarchy

The connector is able to replicate relationships and logical dependencies among these entities. In particular all the available Clusters are attached to the root of the hierarchy and each Cluster contains its own Nodes, Resource Managers and Services.

Services' data is available among the above entities' metrics, according to the following table.

Troubleshooting

For ETL troubleshooting, please refer to official BMC documentation available here.

Known issues

IssueResolution

ETL runs fine but data is partially or totally missing

 

Probably data is missing in the datasource. Check from the Ambari web frontend if data is available, otherwise the following image is shown. In such event consider to enable data collection.
