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).
</para>
<para>
Currently supported debug levels:
</para>
<para>
<emphasis>0</emphasis>, <emphasis>0x0010</emphasis>: Fatal
failures. Anything that would prevent SSSD from starting up or causes it to
cease running.
</para>
<para>
<emphasis>1</emphasis>, <emphasis>0x0020</emphasis>: Critical failures. An
error that doesn't kill SSSD, but one that indicates that at least one major
feature is not going to work properly.
</para>
<para>
<emphasis>2</emphasis>, <emphasis>0x0040</emphasis>: Serious failures. An
error announcing that a particular request or operation has failed.
</para>
<para>
<emphasis>3</emphasis>, <emphasis>0x0080</emphasis>: Minor failures. These
are the errors that would percolate down to cause the operation failure of
2.
</para>
<para>
<emphasis>4</emphasis>, <emphasis>0x0100</emphasis>: Configuration settings.
</para>
<para>
<emphasis>5</emphasis>, <emphasis>0x0200</emphasis>: Function data.
</para>
<para>
<emphasis>6</emphasis>, <emphasis>0x0400</emphasis>: Trace messages for
operation functions.
</para>
<para>
<emphasis>7</emphasis>, <emphasis>0x1000</emphasis>: Trace messages for
internal control functions.
</para>
<para>
<emphasis>8</emphasis>, <emphasis>0x2000</emphasis>: Contents of
function-internal variables that may be interesting.
</para>
<para>
<emphasis>9</emphasis>, <emphasis>0x4000</emphasis>: Extremely low-level
tracing information.
</para>
<para>
<emphasis>10</emphasis>, <emphasis>0x10000</emphasis>: Even more low-level
libldb tracing information. Almost never really required.
</para>
<para>
To log required bitmask debug levels, simply add their numbers together as
shown in following examples:
</para>
<para>
<emphasis>Example</emphasis>: To log fatal failures, critical failures,
serious failures and function data use 0x0270.
</para>
<para>
<emphasis>Example</emphasis>: To log fatal failures, configuration settings,
function data, trace messages for internal control functions use 0x1310.
</para>
<para>
<emphasis>Note</emphasis>: The bitmask format of debug levels was introduced
in 1.7.0.
</para>
<para>
<emphasis>Default</emphasis>: 0x0070 (i.e. fatal, critical and serious
failures; corresponds to setting 2 in decimal notation)
</para>
