EFT Server Activity Log

To monitor EFT activity, you can reference EFT’s log files. EFT supports W3C, Microsoft IIS, and NCSA log file formats. Server events are logged to a file named [log file format]yymmdd.log, where YY, MM, and DD indicate the numeric year, month, and day respectively. Depending on the log file format selected, a 2-letter abbreviation is prepended to the filename, as described in the table below. For example, a log file in the Microsoft IIS format created on August 22, 2024 is named in240822.log.

By default, log files are saved in the EFT data directory in the Log folder (for example, C:\ProgramData\Globalscape\EFT Server\Logs). Outbound connection information is audited in that same folder in a log named cl<date>.log.

When using HA, you need to specify a unique location (local) for the log files. This is for troubleshooting purposes (to know what node an issue occurred on). Also, having two nodes write to the same file causes issues with file locking, which will cause data in the logs to be lost.

Log Format, Type, and Location

To specify log settings

1. In the administration interface, connect to EFT and click the Server tab.

2. On the Server tab, click the Server node.

3. In the right pane, click the Logs tab.

   

4. In the Log File Settings area, in the Folder in which to save log files box, type the path to the directory in which to save this Server's log files. To browse for a path, click the folder icon .

5. In the Log file format list, click W3C Extended, Microsoft IIS, NCSA Common, or No Logging. Changing the log file format disconnects all active users. It is recommended to stop all Sites or wait until all users are inactive before changing the log file format. The W3C format records all times in GMT (Greenwich Mean Time).

6. Clear the Encode logs in UTF-8 check box if you do not want to encode logs in UTF-8 format. When the check box is cleared, the u_ex*.log file is named ex*.log.

   From Microsoft TechNet:

   When using the UTF-8 logging feature, note the following:

   • A log file logged in UTF-8 does not contain a Byte Order Mark (BOM). File editors use this mark to identify text as UTF-8 text. Therefore, if you attempt to open a log file that is logged in UTF-8 in Notepad by double-clicking the file or by using the Open With option, the file might not display correctly. To open the file in a way that displays it correctly, use the Open command on the File menu and then select UTF-8 in the Encoding box.

   • UTF-8 is a double-byte character-set standard. ASCII is a single-byte character-set standard. Because of this disparity, logging UTF-8 information to an ASCII file causes a ? to be logged for the characters that cannot be converted to the code page of the server.

7. In the Log type list, click Standard or Verbose. (Verbose provides more details, but makes larger files.)

8. In the Rotate Log File area, specify Never, Daily, Weekly, or Monthly.

9. Click Apply to save the changes on EFT.

10. Stop and restart EFT.
