8			`Shift`	`eads_command_message.log`
9	Exception log file output during command execution (Exception log information)	Directory specified in the `eads.command.logger.dir` parameter in the command properties	`Wrap`	`eads_command_exception[n].log`
9			`Shift`	`eads_command_exception.log`
10	Maintenance log file output during command execution (maintenance log information)	`directory-specified-in-the-eads.command.logger.dir-parameter-in-the-command-properties/maintenance`	`eads_command_maintenance[n].log`
11	Statistics file (EADS server)	`directory-specified-in-the-eads.logger.dir-parameter-in-the-server-properties/stats`	`eads_stats.csv` `eads_stats_[n].csv`^#1
12	Statistics file (cache)	`directory-specified-in-the-eads.logger.dir-parameter-in-the-server-properties/stats`	`eads_cache_stats.csv` `eads_cache_stats_[n].csv`^#1
13	Statistics file (user functions)	`directory-specified-in-the-eads.logger.dir-parameter-in-the-server-properties/stats`	`eads_function_stats.csv` `eads_function_stats_[n].csv`^#1
14	Statistics file (range)	`directory-specified-in-the-eads.logger.dir-parameter-in-the-server-properties/stats`	`eads_store_stats.csv` `eads_store_stats_[n].csv`^#1
15	Statistics file (maintenance information)	`directory-specified-in-the-eads.logger.dir-parameter-in-the-server-properties/maintenance/stats`	`eads_maintenance_stats.csv` `eads_maintenance_stats_[n].csv`^#1
16	Java log file	Directory specified in the `eads.logger.dir` parameter in the server properties	`javalog[nn].log` `ehjavalog[nn].log`^#2
17	Thread dump	Directory specified in the `eads.logger.dir` parameter in the server properties	`javacore[PID].[YYMMDDhhmmss].txt`
18	Startup log file	Directory specified in the `eads.logger.dir` parameter in the server properties	`eads_start.log`

Legend:

[n], [nn], [nnn]: Sequence number of the file

[PID]: EADS server's process ID

[YYMMDDhhmmss]: YY: year, MM: month, DD: day, hh: hour (00 through 23), mm: minute, ss: second

Wrap, Shift: Log rotation method

You can select either of the following log rotation methods:

Wrap: Wrap-around method

The sequence number of the file is added to the file name.
Shift: Shift method

The file name is fixed.

The sequence number of the file is added to the log file's backup file name.

#1

The statistics files are rotated each day and sequence numbers are assigned to the file names.

When the statistics files are rotated, as many statistics files as specified in the eads.statistics.filenum parameter in the server properties are retained as backup files.

For details about the rotation of statistics files, see 7.4.4 Specifying the rotation of statistics files.

#2

This file is used to output logs related to the explicit heap.

Important note: A directory of another machine that is connected via a network cannot be specified as the file output destination.
