SSSD supports two representations for specifying the debug level. The simplest is to specify a decimal value from 0-9, which represents enabling that level and all lower-level debug messages. The more comprehensive option is to specify a hexadecimal bitmask to enable or disable specific levels (such as if you wish to suppress a level).

Please note that each SSSD service logs into its own log file. Also please note that enabling “debug_level” in the “[sssd]” section only enables debugging just for the sssd process itself, not for the responder or provider processes. The “debug_level” parameter should be added to all sections that you wish to produce debug logs from.

In addition to changing the log level in the config file using the “debug_level” parameter, which is persistent, but requires SSSD restart, it is also possible to change the debug level on the fly using the sss_debuglevel(8) tool.

現在サポートされるデバッグレベル:

0, 0x0010: Fatal failures. Anything that would prevent SSSD from starting up or causes it to cease running.

1, 0x0020: Critical failures. An error that doesn´t kill the SSSD, but one that indicates that at least one major feature is not going to work properly.

2, 0x0040: Serious failures. An error announcing that a particular request or operation has failed.

3, 0x0080: Minor failures. These are the errors that would percolate down to cause the operation failure of 2.

4, 0x0100: Configuration settings.

5, 0x0200: Function data.

6, 0x0400: Trace messages for operation functions.

7, 0x1000: Trace messages for internal control functions.

8, 0x2000: Contents of function-internal variables that may be interesting.

9, 0x4000: Extremely low-level tracing information.

To log required bitmask debug levels, simply add their numbers together as shown in following examples:

例: 致命的なエラー、重大なエラー、深刻なエラーおよび関数データをログに取得するには 0x0270 を使用します。

例: 致命的なエラー、設定値の設定、関数データ、内部制御関数のトレースメッセージをログに取得するには 0x1310 を使用します。

Note: The bitmask format of debug levels was introduced in 1.7.0.

Default: 0
