Troubleshooting tools

The ION Grid provides many sources of information about the configuration and runtime status of a grid and the applications running within the grid. These include:

• Log files

  Log files are available for each node. For more information, see Viewing log files.

• Counters

  Counters are available for each grid node as well as a counter history. For more information, see Viewing counters.

• Configuration history

  You can review a history of changes to the grid configuration so that you can, for example, identify changes that caused a problem or revert to a previous configuration. For more information, see Comparing runtime history.

• Heap dumps and thread dumps

  You can view heap dumps and thread dumps for individual grid nodes.

• Grid Status report

  The Grid Status report is a generated report that shows the overall status of the grid, and also includes log files, configuration files. For more information, see Generating a Grid Status report and Viewing a Grid Status report.
