This document only describes the parameters that are not included in command-line parameters. For more details, see [command-line parameter](/command-line-flags-for-tikv-configuration.md).

### server
## Global configuration

### `log-level`

+ The log level
+ Value options: "trace", "debug", "info", "warning", "error", "critical"
+ Default value: "info"

### `log-file`

+ The log file. If this configuration is not set, logs are output to "stderr" by default.
+ Default value: ""

### `log-format`

+ The log format
+ Value options: "json", "text"
+ Default value: "text"

### `log-rotation-timespan`

+ The timespan between log rotations. When this timespan passes, log files are rotated, that is, a timestamp is appended to the file name of the current log file, and a new file is created.
+ Default value: "24h"

### `log-rotation-size`

+ The size of a log file that triggers log rotation. Once the size of a log file is bigger than the specified threshold value, log files are rotated. The old log file is placed into the new file, and the new file name is the old file name with a timestamp suffix.
+ Default value: "300MB"

### `slow-log-file`

+ The file to store slow logs
+ If this configuration is not set but `log-file` is set, slow logs are output to the log file specified by `log-file`. If neither `slow-log-file` nor `log-file` are set, all logs are output to "stderr".
+ Default value: ""

### `slow-log-threshold`

+ The threshold for outputing slow logs. If the processing time is longer than this threshold, slow logs are output.
+ Default value: "1s"
