Session Profiles → Logging

The name defined here will be used as filename for the logfile. The name can contain absolute or relative folder paths (folders in the path, especially when containing placeholders, will be created as necessary).

It is also possible to create dynamic names and folders by using placeholders for date and time, which will be substituted with their respective values when the log is opened (see placeholder codes in the appendix). Examples are ^+_^1^2^3.log or Host_^+\Log_^3_^2_^1.log (the latter is a logfile in a dynamically created subfolder).

Note: Unless you supply an absolute path with the logfile name, the file will be placed in the log directory which is configured in Options→Program Settings→Folders.

If a logfile already exists, it can be overwritten (Overwrite file), or the new data can be appended (Append data to file). As an alternative the filename can be incremented (Increment filename) to make sure that no existing logfile will be overwritten.

Enable saving incoming data in the logfile. This function is identical to setting checkmark near the logfile name in the status bar or to using the Log to File entry in the Logging menu.

If this option is active and if the filename for the logfile contains placeholders for year, month, day or hour, ZOC will create a new logfile as soon as a new day/hour/etc. begins.

This option will insert time stamps before each line of the log. The time stamps will indicate, when exactly the data was received. A marker looks like [2026-10-05 16:47:58.2].

When time markers are enabled, this option includes the date in the marker, as in the example above. Without it, only the time is written.

Session headers are a few lines of extra information in the log. They contain information about when a session starts, which host you connected to etc.

Cursor placement, colors and other screen controls for terminal emulations are performed by adding invisible control codes to the data. This option controls, if these codes should be added to the logfile or not (normally they are of little interest to the end user).

This option improves performance when writing the logfile. ZOC collects more data in memory before writing it to the file.

Some hosts are able to remotely suspend/resume logging by sending DC2 (^R) and DC4 (^T) characters (the checkmark in the status line will turn gray if the host suspends logging for you). This option enables/disables the ability of the host to control the logging.

Opens the logfiles folder. This is the same as Show Logfiles Folder in the Logging menu.
