@Rocky How to make BE logs emitted to console/stdout?

To make StarRocks Backend (BE) logs emit to the console or stdout, the configuration depends on your version and deployment environment. 1. For StarRocks v3.2 and later (FE only) StarRocks introduced a native configuration for FE to log to the console. While there is no identical parameter for BE in the official

be.conf

documentation, FE users can set: * In

fe.conf

:

sys_log_to_console = true

* Environment Variable:

SYS_LOG_TO_CONSOLE=1

2. For BE (Backend) The BE uses

glog

for logging, which defaults to writing files (e.g.,

<http://be.INFO|be.INFO>

,

be.WARN

). As of the latest documentation, there is no direct

sys_log_to_console

parameter in

be.conf

like there is for FE. To achieve console logging for BE: A. Using Environment Variables (glog) Because BE uses

glog

, you can attempt to force it to log to stderr (which usually pipes to stdout in container environments) by setting the following environment variables before starting the BE process:

bash
export GLOG_logtostderr=1

Note: This might bypass the standard StarRocks log file rotation and formatting. B. In Docker/Kubernetes Environments If you are using the StarRocks Docker image or Helm chart: * Symlinking: The StarRocks Kubernetes Operator and official Docker images often handle this by symlinking the log files to

/dev/stdout

or

/dev/stderr

. * Tail approach: A common workaround in custom Docker setups is to redirect the BE log directory to a volume and run a sidecar or a background process:

bash
    tail -f /path/to/starrocks/be/log/be.INFO

3. StarRocks v3.3+ Dynamic Configuration In StarRocks v3.3.0+,

sys_log_level

became a dynamic parameter, but

sys_log_to_console

remains a static startup configuration for components that support it. Summary for BE: There is no direct

be.conf

parameter for "log to console" in the same way as FE. You should either: 1. Use environment variables like

GLOG_logtostderr=1

. 2. In container environments, ensure your entrypoint script or orchestration (like the StarRocks Operator) handles the redirection of the log files located in

sys_log_dir

. For official containerized deployments, it is recommended to use the StarRocks Kubernetes Operator, which handles log collection and console output natively.
