## Logging
Logging adds detail and allows the node operator to better identify what they are looking for. Tendermint supports log levels on a global and per-module basis. This allows the node operator to see only the information they need and the developer to hone in on specific changes they are working on.
Logging adds detail and allows the node operator to better identify what they are looking for. Tendermint supports log levels on a global and per-module basis. This allows the node operator to see only the information they need and the developer to hone in on specific changes they are working on.
## Configuring Log Levels
There are three log levels, `info`, `debug` and `error`. These can be configured either through the command line via `tendermint start --log-level ""` or within the `config.toml` file.
- `info` Info represents an informational message. It is used to show that modules have started, stopped and how they are functioning.
- `debug` Debug is used to trace various calls or problems. Debug is used widely throughout a codebase and can lead to overly verbose logging.
- `error` Error represents something that has gone wrong. An error log can represent a potential problem that can lead to a node halt.
The default setting is a global `main:info,state:info,statesync:info,*:error` level. If you would like to set the log level for a specific module, it can be done in the following format:
> We are setting all modules to log level `info` and the mempool to `error`. This will log all errors within the mempool module.
- `error` Error represents something that has gone wrong. An error log can represent a potential problem that can lead to a node halt.
Within the `config.toml`:
```toml
# Output level for logging, including package level options
log-level = "*:info,mempool:error"
log-level = "info"
```
Via the command line:
```sh
tendermint start --log-level "*:info,mempool:error"
tendermint start --log-level "info"
```
