This section controls the logging levels for different areas of the code. It contains the following keys, all of which have string values and are optional:

default (determines the default logging level for all areas)
Legacy
Main
Experiment
Box
Collider
Sphere
Action
InputParser
ParticleType
FindScatter
Clock
DecayModes
Resonances
ScatterAction
Distributions
Propagation
Grid
List
Nucleus
Density
PauliBlocking
Tmn
Fpe
Lattice
Pythia
GrandcanThermalizer
CrossSections
Output

Each key can have one of the following values:

ALL - Log all messages (default)
TRACE - The lowest severity for messages describing the program flow
DEBUG - Debug messages
INFO - Messages of informational nature
WARN - Warning messages
ERROR - Non-fatal errors
FATAL - Messages that indicate terminal application failure
OFF - If selected no messages will be output

Note that the logging levels TRACE and DEBUG are only available in debugging builds (i.e. with -DCMAKE_BUILD_TYPE=Debug).

Example: Configuring the Logging Area
