# Change Log Level on the Fly
|
|
|
|
## HTTP API
|
|
|
|
example:
|
|
```bash
|
|
curl --data "trace,flow=debug" 127.0.0.1:4000/debug/log_level
|
|
```
|
|
And database will reply with something like:
|
|
```bash
|
|
Log Level changed from Some("info") to "trace,flow=debug"%
|
|
```
|
|
|
|
The data is a string in the format of `global_level,module1=level1,module2=level2,...` that follows the same rule of `RUST_LOG`.
|
|
|
|
The module is the module name of the log, and the level is the log level. The log level can be one of the following: `trace`, `debug`, `info`, `warn`, `error`, `off`(case insensitive).
