# 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 follow 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).
