Logging Levels

The table below describes the logging levels which are configurable for server components.


Only outputs errors. An error is a serious problem, typically requiring operator intervention of some sort to restore full functionality.


Outputs errors and warnings. A warning indicates a potential problem, where the system can nonetheless function without intervention.


Outputs general information in addition to the errors and warnings. This is the default.


Outputs debugging information in addition to all the previous levels.

TraceOutputs the maximum information available. Used only in exceptional circumstances as it will generate huge amounts of logging output.
Logging levels should only be changed from info only if requested by 1E Support and reset to info after investigation is complete.

The method of configuring logging levels for the Tachyon Switch changed in v3.3 to using the above text values, but retains -log=0 as the default to mean the same as -log=info.
