Downloading System/Log Files

* 
NOTE: Some log file names, such as those found in the commonlogs directory, contain a two-digit number such as 12.log. The 12 indicates that the log is for the 12th day of the most recent month. Some log file names end with a digit, such as MlfThumbUpdate_2.log. The _2 indicates that this is an older log. The current log is MlfThumbUpdate.log. The next most recent log is MlfThumbUpdate_0.log, followed by MlfThumbUpdate_1.log, and so forth.

Most log data is in Greenwich Mean Time (GMT), not in the local time of the server the logs come from. This applies to the names of the log files as well.

All logs adhere to the default level set here unless specifically overridden.

Optionally, select the number of log files to retain. By default, Junk Box keeps 3 log files for these services:
 
•
SMTP
•
Thumbprint Updater
•
Resources Monitor
•
Replicator
•

•

When a fourth log file is generated, the oldest log file is discarded, the second oldest becomes the oldest, and the third oldest becomes the second oldest.

You can increase the number of logs kept for a service by selecting a number from the Count drop-down menu for that service:

•

•

•

A lower number of logs saves disk space, but older data may not be available. A larger number of logs retains more data, but takes more disk space.

Optionally, select a size for the service logs (see Step 6) from the Size drop-down menus. The default size of each log is 10 Mb.

You can increase the size of he logs, in 10 MB increments, from 10 Mb (default) to 100 Mb. A smaller log size saves disk space, but larger logs contain more data.

IMPORTANT: Changing the size of a log requires restarting the Tomcat server.
