Logging Configuration
Logging in Nethermind is done via NLog library that can be configured by editing the NLog.config file.
Environment Type | NLog.config location |
built from src - Debug mode | src\Nethermind\Nethermind.Runner\bin\Debug\netcoreapp3.1\NLog.config |
built from src - Release mode | src\Nethermind\Nethermind.Runner\bin\Release\netcoreapp3.1\NLog.config |
PPA | /usr/share/nethermind/NLog.config |
Docker | /nethermind/NLog.config |

Simple logging rules can be added through configuration file or command line argument.
For example this would add
Trace level logs to any logger under Synchronization module and Debug level logs for BlockTree from Blockchain module:
--Init.LogRules Synchronization.*:Trace;Blockchain.BlockTree:DebugAdditionally there are global logging override that you can use temporarily:
Command line override | Log level |
./Nethermind.Runner --config mainnet --log TRACE | TRACE |
./Nethermind.Runner --config mainnet --log DEBUG | DEBUG |
./Nethermind.Runner --config mainnet --log INFO | INFO |
./Nethermind.Runner --config mainnet --log WARN | WARN |
./Nethermind.Runner --config mainnet --log ERROR | ERROR |
This can be done by including these lines in the logging configuration file:
<logger name="JsonRpc.*" minlevel="Error" writeTo="file-async"/>
<logger name="JsonRpc.*" minlevel="Error" writeTo="auto-colored-console-async" final="true"/>
<logger name="JsonRpc.*" final="true"/>
