## EMQX provides support for two primary log handlers: `file` and `console`, with an additional `audit` handler specifically designed to always direct logs to files.
|
||||
## The system's default log handling behavior can be configured via the environment variable `EMQX_DEFAULT_LOG_HANDLER`, which accepts the following settings:
|
||||
##
|
||||
## - `file`: Directs log output exclusively to files.
|
||||
## - `console`: Channels log output solely to the console.
|
||||
##
|
||||
## It's noteworthy that `EMQX_DEFAULT_LOG_HANDLER` is set to `file` when EMQX is initiated via systemd `emqx.service` file.
|
||||
## In scenarios outside systemd initiation, `console` serves as the default log handler.
|
||||
|
||||
## Read more about configs here: {{ emqx_configuration_doc_log }}
