What is your question?

On the docs, there's a page explaining various settings related to logging. However, there's no instruction about where or how to set those variables. Is log.level an environment variable? Do I set this on a file? It isn't clear.

Anything else?

The target configuration file (that contains log level settings) is inside milvus container, at /milvus/configs/milvus.yaml. You can either

1. Go inside the container and modify the milvus.yaml, or
2. Write another milvus.yaml outside the container, and modify docker-compose.yml to mount and map that file.

Assuming you are using milvus-standalone,

• For option 1, you may
  1. Go inside the container

     docker exec -it docker-standalone bash
     

  2. Install a text editor

     apt update
     apt install nano
     

  3. Edit the file

     nano /milvus/configs/milvus.yaml
     

• For option 2, you may
  1. Write a milvus.yaml with log settings:

     # Configures the system log output.
     log:
       level: warn # Only supports debug, info, warn, error, panic, or fatal. Default 'info'.
       file:
         rootPath: # root dir path to put logs, default "" means no log file will print. please adjust in embedded Milvus: /tmp/milvus/logs
         maxSize: 300 # MB
         maxAge: 10 # Maximum time for log retention in day.
         maxBackups: 20
       format: text # text or json
       stdout: true # Stdout enable or not
     

  2. Open docker-compose.yml and locate standalone.volumes
  3. Modify docker-compose.yml:

     standalone:
       ...
       volumes:
         ...
         <full path of milvus.yaml>:/milvus/configs/milvus.yaml
       ...
     

In addition, you can also change log level during runtime:

curl -X PUT localhost:9091/log/level -d "level=warn" # assuming server is localhost and target level is warn
