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 Viewing Configuration History.

• Heap dumps and thread dumps

  You can view heap dumps and thread dumps for individual grid nodes. For more information, see Getting a Heap Dump or Thread Dump Via the Grid Agent.

• Network Diagnostics

  The grid provides three network tests. For more information, see Diagnosing Network Issues.

• 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, counter history, and thread dumps. For more information, see Generating a Grid Status Report and Viewing a Grid Status Report.
