dynaFile¶

For each message, the file name is generated based on the given template.

This parameter applies to omfile: File Output Module.

Name:: dynaFile
Scope:: action
Type:: string
Default:: action=none
Required?:: no
Introduced:: at least 8.x, possibly earlier

Description¶

For each message, the file name is generated based on the given template. Then, this file is opened. As with the file property, data is appended if the file already exists. If the file does not exist, a new file is created. The template given in “templateName” is just a regular rsyslog template, so you have full control over how to format the file name.

To avoid path traversal attacks, you must make sure that the template used properly escapes file paths. This is done by using the securepath parameter in the template’s property statements, or the secpath-drop or secpath-replace property options with the property replacer.

Either file or dynaFile can be used, but not both. If both are given, dynaFile will be used.

A cache of recent files is kept. Note that this cache can consume quite some memory (especially if large buffer sizes are used). Files are kept open as long as they stay inside the cache. Files are removed from the cache when a HUP signal is sent, the closeTimeout occurs, or the cache runs out of space, in which case the least recently used entry is evicted.
