HPE Ezmeral Data Fabric Control System

Provides a brief description of the HPE Ezmeral Data Fabric Control System.

The HPE Ezmeral Data Fabric Control System provides a graphical control panel for cluster administration with all the functionality of the command-line or REST APIs. The Control System provides job monitoring metrics and helps you troubleshoot issues, such as which jobs required the most memory in a given week, or which events caused job and task failures.

The Control System provides various views, which you can use to configure and monitor your cluster:

Overview
The Control System Overview page provides a summary of information about the cluster including a cluster heat map that displays the health of each node organized by service, an alarms summary, cluster utilization that shows the CPU, memory, and disk space usage, the number of available, unavailable, and under replicated volumes, and MapReduce applications.
Attention: This page is not available when running on a Kubernetes cluster.
Services

The Control System Services page provides a summary of the services running across the cluster.

Nodes
The Control System Nodes page provides a summary of information about the nodes on the cluster including a heat map that displays the health of each node, resource utilization that shows the CPU and memory usage, all active alarms, and a list of all the nodes on the cluster with links that provide shortcuts to more detailed information about the node.
Attention: This page is not available when running on a Kubernetes cluster.
Data
The Control System Data drop-down menu contains links to pages that provide summary of information about volumes, tables, and streams.
Attention: This page is not available when running on a Kubernetes cluster.
Admin
The Control System Admin drop-down menu contains links to pages for user and cluster management tasks such as setting up permissions, quotas, and email settings for users, enabling cluster-level and data auditing, configuring balancer settings, and adding licenses.
Note: During installation using the Installer, you can configure metrics and logging using settings on the Monitoring page of the Installer user interface. The metrics collection infrastructure must be installed because the Control System relies on these metrics to provide graphs and charts. If the metrics collection infrastructure is not installed, you cannot visualize the metrics in the panes on the Control System.

URL Sharing Feature

The Control System supports URL Sharing. As one uses filters and sort column information, the URL records these filters. This URL can then be shared with other users who can then login and view the filtered information.
Note:
  • Filters will be preserved if one logs in as the same user within the current session.
  • Filters will not be preserved if one logs in as a different user within the current session.
  • URL can be shared with any valid user and can be opened in any browser, using valid user credentials.

URL Sharing works on the Volumes page, Security Policies page, Nodes page, and the Snapshots tab both in the Volumes page and the Volume Details page.
