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.
