The Diagnostics page allows you to enable, configure and disable various methods of diagnostic logging, within VPOP3.
By default, VPOP3 will keep two copies of most log files:
Where the settings are changed, causing additional old copies of the log to be retained, all older archives are renamed in the following way:
The General tab allows you to specify the directory where VPOP3 will store the log files, change settings for the main VPOP3 log file, and preview some important log files.
Log Path*: Since version 5, the default location is the _logs folder, within the VPOP3 directory. e.g. C:\VPOP3\_logs
Log Level: How much is logged into the main diagnostic file, vpop3.log (Setting this to Full Logging may cause VPOP3 to run more slowly, but this is rarely noticeable).
Maximum log size: How large (in kilobytes) vpop3.log will be allowed to grow, before it is archived as vpop3.lbk
There are also buttons to preview various log files:
* This setting does not affect certain log files, such as exceptions.log, which VPOP3 writes to when there is a significant performance issue, or a crash is imminent. To save time, and therefore increase the likelihood of VPOP3 being able to record the event, it will only look for exceptions.log in the root of the VPOP3 directory.
The Session Logs tab allows you to administer logging of VPOP3's various services, along with its actions when it takes on the role of a client.
Maximum log size: Allows you to change the size of the session .log files, before they are archived into a .lbk.
The Temporary/Archived Files tab allows you to enable a specific kind of logging, that is rarely (but occasionally) applicable in recent versions of VPOP3.
Because the files are now of very limited use, we do not recommend enabling these options, unless our Support team have specifically told you to do so.
When these settings are enabled, VPOP3 will rename certain redundant files, instead of deleting them, so they can be inspected afterwards.
There are three checkboxes:
There are two buttons, which will remove all retained temporary and error files:
The Log File Sizes tab allows you to control the maximum size of various types of log file, and how long the files are kept.
Note: Despite these settings, VPOP3 will not delete any .log file, or the most recent .lbk file.
It is possible to set the maximum file size, for the following logs:
