You can acquire the data required for troubleshooting with any of the following methods:

• Acquire automatically when a problem occurs
• Acquire in a batch using the management command
• Collect each information separately

The information required for troubleshooting can be collected by compiling it together as a snapshot log. The status, when a problem occurs in the component software in a system, is output to the snapshot log. In a system built with the Application Server, you can collect the snapshot log for each type of component software collectively and output as a log file in a ZIP format. Furthermore, the snapshot log can be acquired by dividing into primary delivery data and secondary delivery data. You can also use the snapshotlog command to collect the definition sending data.

This section describes the snapshot logs for data acquisition in a batch and the failure detection commands executed for data acquisition, as methods for data acquisition when a trouble occurs.

For details about the information that is not acquired as a snapshot log, see 2.4.3 Correspondence Between Acquisition Methods and Investigation Methods and for details about the methods for acquiring the respective information individually, see 4. Output Destinations and Output Methods of Data Required for Troubleshooting.

Note that you need to specify the settings in advance depending upon the data to be acquired. For example, the data such as OS statistics or user dump will not be obtained unless you specify the settings for acquiring this data when building the system. Hitachi recommends that you obtain this data because it is required for troubleshooting.

You can change the default settings to obtain the data such as the output destination of the log file, number of log files, and the maximum size of each file. Change the settings for acquiring data as per your requirements.

The data that cannot be collected as snapshot log as per the default settings, can be collected collectively in the form of a snapshot log by defining the get destination of the data as the target of snapshot log collection.

Note

Notes on data collection settings in Windows

With Windows Server 2012, Windows Server 2008, Windows 8, Windows 7, and Windows Vista, you must specify the settings in the registry to obtain data for investigation when an error occurs. The registry settings affect the whole system, so take adequate precautions when you specify the settings.

Note that with Windows Vista without the service pack, you cannot obtain the data required for troubleshooting even if you specify the registry settings.

For details about the data acquisition settings required for troubleshooting, see 3. Preparing for Troubleshooting.
