Log Configuration File
This section describes how to set the log levels, log output paths, log file names, and log file sizes.
When modifying the log configuration items, follow the recommended values or value ranges described in Table 1-3. Otherwise, system exceptions may occur.
In multi-user scenarios, the configuration file can only be modified by the running user of the log process.
You can manually modify the host-side or device-side configuration file and restart the slogd process separately for the configuration to take effect. You can also run the reboot command to reboot the system for the host-side configuration file to take effect. Restarting the system for the configuration file to take effect is not supported on the device side.
slog.conf
The /var/log/npu/conf/slog/slog.conf file controls the configuration of Slog log collection. The following is a configuration example.

Table 1-3 describes the configuration items.

Description |
|---|---|
Modifications to the following parameters take effect on the device or host side separately. |
|
global_level |
Global log level:
|
enableEvent |
Event log enable:
|
SLOG, IDEDD, IDEDH... |
Log level of a module:
NOTE:
|
The following parameters take effect only on the host side. |
|
LogAgentMaxFileNum |
Number of log files stored on the host side. Defaults to 30. When the number of log files is greater than this value, the new log overwrites the earliest log. |
logAgentMaxFileSize |
Size of a single log file. Defaults to 50 MB. When the size of a log file is greater than this value, a new log file is generated. NOTE:
If the configured value is smaller than 1 MB, 1 MB is used by default. |
logAgentFileDir |
Log file path NOTE:
|
permission_for_all |
Whether to allow a user of a group different from the slogd running user to write logs during app execution.
|
The following parameters take effect only on the device side. |
|
TS, TSDUMP, AI CPU, LP, IMU and IMP |
