Output contents

Number
|
The serial number of trace code (four digits) is output. The number starts from 0000 and returns to 0000, when the number reaches 9999.
|
|
Date
|
The date (yyyy/mm/dd format), during the output, is output.
|
|
Time
|
The time (hh:mm:ss.nnn format), during the output, is output.
|
|
AppName
|
The application-distinguished name is output. You specify the application-distinguished name within 16 bytes. If the length
limit is exceeded, the value after that limit is truncated.
|
|
pid
|
The process-distinguished name (hexadecimal) is output. This value differs from the value that manages the OS.
In the case of a log output by using CJMessageFileHandler, the hash value that is assigned to the Runtime instance by JavaVM is output.
In the case of a log output by using CJMPMessageFileHandler, the lower level 32 bits, during the time (in milliseconds) at which Hitachi Trace Common Library is loaded by JavaVM, is
output.
|
|
tid
|
The thread-distinguished name (hexadecimal) is output. This is a hash value assigned to the Thread instance by JavaVM. This value differs from the value that manages the OS.
|
|
MsgID
|
The message ID is output. You specify a message ID within 21 bytes. If the length limit exceeds, the value after that limit
is truncated.
|
|
Message text
|
This is a message body. This is a string that does not contain the control characters such as CR (0x0D), LF (0x0A), NULL (0x00), and EOF (0x1A). You specify a length from 0 through 4,095 characters. If the length limit exceeds, the value after that limit is truncated.
Note that if you include control characters, output contents are not guaranteed.

|
CRLF
|
The record terminal code (0x0D or 0x0A) is output.
