This subsection describes the settings to acquire the data for troubleshooting using the failure detection time commands. You can collect the material acquired by using the failure detection time commands as the snapshot log.

There are 2 types of failure detection time commands namely, system provided commands and user created commands. According to the default settings, when an error occurs in a logical server, the failure detection time commands provided by the system are executed and thread dumps and trace based performance analysis are acquired. The snapshot log is collected before terminating the logical server where the error occurs. For the information that can be collected by using the failure detection time command provided by system, see 2.3.2(1) Information that can be acquired by executing the failure detection time commands provided by the system.

To change the operation settings for the failure detection time commands provided by the system, you must make environment settings in Management Server and Administration Agent. When using the failure detection time commands created by the user, you must make environment settings in Management Server and Administration Agent as well as create a command file for the failure detection time commands created by the user. For respective settings, see 3.3.1 Data acquisition settings using failure detection time commands (Systems for executing J2EE applications). Here, read "J2EE server" as "Batch server".

Note

To collect the material acquired by the user created failure detection time commands as the snapshot log, you need to add the collection destination of that material to the snapshot log collection destination. For details about addition of the snapshot log collection destination, see 3.3.3(3) Customizing the snapshot log collection destination.
