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 |
Docker | /nethermind/NLog.config |
from downloads page | top level directory after unzipping the package |
from GitHub releases page | top level directory after unzipping the package |
dAppNode | ? [to be documented] |
Detailed NLog configuration options can be found here: https://nlog-project.org/config/
Additionally 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"/>
