help
If enabled, then if there is no space to log a new message, the
oldest one is dropped. If disabled, current message is dropped.
config LOG_BLOCK_IN_THREAD
bool "Block in thread context on full"

help
When enabled logger will block (if in the thread context) when
internal logger buffer is full and new message cannot be allocated.

depends on LOG_BLOCK_IN_THREAD
help
If new buffer for a log message cannot be allocated in that time, log
message is dropped. Forever blocking (-1) is possible however may lead
to the logger deadlock if logging is enabled in threads used for
logging (e.g. logger or shell thread).

help
When number of buffered messages reaches the threshold thread is waken
up. Log processing thread ID is provided during log initialization.
Set 0 to disable the feature. If LOG_PROCESS_THREAD is enabled then
this threshold is used by the internal thread.
config LOG_PROCESS_THREAD
bool "Use internal thread for log processing"
depends on MULTITHREADING
default y
help
When enabled thread is created by the logger subsystem. Thread is
waken up periodically (see LOG_PROCESS_THREAD_SLEEP_MS) and whenever
number of buffered messages exceeds the threshold (see
LOG_PROCESS_TRIGGER_THR).

Log processing thread starts after requested delay given in
milliseconds. When started, thread process any buffered messages.

If enabled, logger will assert and log error message is it detects
that string format specifier (%s) and string address which is not from
read only memory section and not from pool used for string duplicates.
String argument must be duplicated in that case using log_strdup().
Detection is performed during log processing thus it does not impact
logging timing.

Number of calls to log_strdup() which can be pending before flushed
to output. If "<log_strdup alloc failed>" message is seen in the log
output, it means this value is too small and should be increased.
Each entry takes CONFIG_LOG_STRDUP_MAX_STRING bytes of memory plus
some additional fixed overhead.

When enabled, maximal utilization of the pool is tracked. It can
be read out using shell command.
