Diagnostics

• This is tool is used to control the behaviour of your HDB++ system.
• It controls your ‘HdbConfiguratorManager’ and ‘HdbEventSubscriber’ devices.
• It can be launched by View / Diagnostics menu in configurator GUI.
• Or directly by the command: java org.tango.hdb_configurator.diagnostics.HdbDiagnostics

Main window

• The main window display a table where:

  • rows are archivers (last row is the manager).

  • columns are the number of attribute faulty, started, paused, stopped and statistics.

    And finaly the archiver context.

  

• By a double click on a cell (or using right click menu) you can have a detailed display.

Faulty attributes

• If you click on a Faulty cell, you can see:

  • The list of faulty attributes
  • The error message

• By a right click on Selection Column, you can stop or remove selected attributes.

Attribute statistics

• Some statistics are computed (Events and Failures by period) by the HdbEventSubscriber device.
• For instance if the property StatisticsTimeWindow is 1, you have the number of events and failures by seconds.
• If you click on a statistics cell you will have statistics by attribute since last reset.

Change context

• If you double click on l;ast column (Context), you can change the specified HdbEventSubscriber context.
• The better way is to do it on HdbConfiguratorManager (last row) to change context on all archivers.

Distribution

Distribution window is available using View / Distribution menu.

• The first tab gives a chart displaying the distribution:

  • Number of faulty attributes by archiver.
  • Number of OK attributes by archiver.
  • Number of events received by archiver since last reset.

* The second tab gives a chart displaying the maximum: - Process time (from event reception to storage) - Store time (time to store value) - Pending (number of attributes waiting to be archived)

* The third tab gives the same information as numeric values in a table.
