  1. Establish connection to a Hadoop server

  2. Adjust the preview layout

  3. Filter out the parameters to monitor

At any time, you can open the connection settings in one of the following ways:

  • Go to the Tools | Big Data Tools settings page  CtrlAlt0S.

  • Click settings on the Hadoop YARN tool window toolbar.

Once you have established a connection to the Hadoop server, the Hadoop YARN tool window appears. It consists of the several areas to monitor data for:

For more information about types of data, refer to Hadoop documentation.

Once you have set up the layout of the monitoring window, opened or closed some preview areas, you can filter the monitoring data to preview particular parameters.

At any time, you can click Refresh on the Hadoop YARN tool window to manually refresh the monitoring data. Alternatively, you can configure the automatic update within a certain time interval in the list located next to the Refresh button. You can select 5, 10, or 30 seconds.
