How to set log level for IoTDB cluster?

[chengjianyun]

Hi, there

I'd like to change the log level of some packages for IoTDB cluster, I made some change in conf/logback.xml. But it doesn't take effect. Could anyone help?

Thanks!

Have you tried to change < root level = "info" > in logback.xml to < root level = "debug" >

[chengjianyun]

Yes, I did do that but didn't take effect. Does it work on your side?

[ijihang]

Yes, it takes effect, and the debug log will be output to the debug.log file

Thanks, @ijihang. I think it needs to update the logback.xml while mvn package. Just update the logback.xml under config folder in the running environment doesn't take effect.
