logger_tree {lgr}

Logger Tree

Description

Displays a tree structure of all registered Loggers.

Usage

logger_tree()

Value

data.frame with subclass "logger_tree"

Symbology

• unconfigured Loggers are displayed in gray (if your terminal supports colors and you have the package crayon installed).

• If a logger's threshold is set, it is displayed in square brackets next to its name (reminder: if the threshold is not set, it is inherited from next logger up the logger tree).

• If a logger's propagate field is set to FALSE an red hash (⁠#⁠) sign is displayed in front of the logger name, to imply that it does not pass LogEvents up the tree.
