Where are the Client or Server logs located?

This is a reference of the log locations for Enterprise Server, Connect Server, Point to Point, and Aspera Client. The log location differs by operating system and whether the install was done for All Users on the machine or a Single User.

When sending logs to Aspera it is best to zip or tar up the entire log directory

GUI on all platforms

If you use the graphical user interface for your product, you can access your logs easily from here.

Go to Tools > Open Logs folder on your product's main toolbar to open the folder that contains all the log files.




Replace user with the logged in username, and product_name with the name of your product, such as Enterprise Server.

Any Windows (All Users)

  • C:\Program Files [(x86)]\Aspera\product_name\var\log

Windows Vista, 7, 2008 Server (Single User)

  • C:\Users\user\AppData\Local\Programs\Aspera\product_name\var\log

 Windows XP, 2003 Server (Single User, or non-admin install)

  •  C:\Documents and Settings\user\Application Data\Aspera\product_name\var\log


For root user:

  • /Library/Logs/Aspera

For all other users, where user is the name of the account:

  • /Users/user/Library/Logs/Aspera


Most Aspera processes use the rsyslog facility local2. It goes by default to:

  • /var/log/messages

If segregated it may be found in:

  • /var/log/aspera.log

Refer to this article for more details.


  • /var/log/syslog

On Demand

If you are using an On Demand transfer server, the log files are at the following locations:

  • /opt/aspera/var/log
  • /var/log/aspera.log

Note that /opt/aspera/var/log contains directories for alee and trapd, both of which contain logs that should be sent to Support engineers. For more information on trapd, see this Knowledge Base article: How To Debug Trap.


  • /var/log/aspera.log


  • /var/log/messages


  • /var/log/aspera.log


The Aspera processes use the rsyslog facility local2.

To redirect aspera logs to a file, configure syslog accordingly:

echo 'local2.debug /var/log/aspera.log' >> /etc/syslog.conf
touch /var/log/aspera.log
refresh -s syslogd

Syslogd also supports log rotation and compression.

msg_src_list destination [rotate [size sizek|m] [files files] [time timeh|d|w|m|y] [compress] [archive archive]]

For example, to enable log rotation by 50MB on 10 files, add the record below to /etc/syslog.conf:

local2.debug /var/log/aspera.log rotate size 50m files 10

Then, refresh the configuration:

# refresh -s syslogd

To remove Aspera logs from other rules, add level2.none to the related record.

Note: The maximum file size for the syslogd log file cannot exceed 2GB.
