HICC stands for Hadoop Infrastructure Care Center. It is the central dashboard for visualize and monitoring of metrics collected by Chukwa.

How HICC is organized

To get started with HICC, you should get to know the menus and tools of the dashboard, and learn how widgets and information are organized.


When you login to HICC, the dashboard appears. You'll see a menu bar along the top of the browser window, and widgets in rows and columns. In between the menu bar and the widgets is the tabs. In the upper right corner of dashboard are the icons for HICC global options.

How widgets are organized

HICC organizes widgets in Widgets Catalog where information are organized in a tree structure. Some of the categories are described below.

  • Developer A list of utility widgets for exploring metrics stored on HBase and debugging tools to help developer to develope new widgets.
  • Global A list of utility widgets for user to control time, cluster, or host selection.
  • Hadoop Hadoop related metrics and job summary are organized in this category.
  • System Metrics System related metrics such as cpu, disk, network or memory utilization are organized in this category.

Navigating HICC

The items stored on HICC -- including applications, utilities and widgets -- are organized in a hierarchy of widget category that you can browse by accessing menu bar "Options". The dashboard has columns and rows and you can rearrange the layout of the widgets by drag and drop. Rearranging widgets on the dashboard is only saved when "Save Dashboard" is click.
