Logging Service

Define to enable CLI logging and otLogCli() OT function.

The log level (used at compile time).

If OPENTHREAD_CONFIG_LOG_LEVEL_DYNAMIC_ENABLE is set, this defines the most verbose log level possible. See OPENTHREAD_CONFIG_LOG_LEVEL_INIT to set the initial log level.

Define as 1 to enable dynamic log level control.

Note that the OPENTHREAD_CONFIG_LOG_LEVEL determines the log level at compile time. The dynamic log level control (if enabled) only allows decreasing the log level from the compile time value.

The initial log level used when OpenThread is initialized.

See OPENTHREAD_CONFIG_LOG_LEVEL_DYNAMIC_ENABLE.

The maximum log string size (number of chars).

Selects if, and where the LOG output goes to.

There are several options available

• OPENTHREAD_CONFIG_LOG_OUTPUT_NONE
  
• OPENTHREAD_CONFIG_LOG_OUTPUT_DEBUG_UART
  
• OPENTHREAD_CONFIG_LOG_OUTPUT_APP
  
• OPENTHREAD_CONFIG_LOG_OUTPUT_PLATFORM_DEFINED
  
• and others

Note:

1) Because the default is: OPENTHREAD_CONFIG_LOG_OUTPUT_PLATFORM_DEFINED The platform is expected to provide at least a stub for otPlatLog().

2) This is effectively an ENUM so it can be if/else/endif at compile time.

Log output goes to the "application" provided otPlatLog() in NCP and CLI code.

Log output goes to the debug uart - requires OPENTHREAD_CONFIG_ENABLE_DEBUG_UART to be enabled.

Log output goes to the bit bucket (disabled)

Log output is handled by a platform defined function.

Define to enable dump logs (of packets).

Define to enable platform logging and otLog{Level}Plat() OT functions.

Define to prepend the log level to all log messages.

Define as 1 to prepend the current uptime to all log messages.

If defined as 1 when IPv6 message info is logged in mesh-forwarder, the source and destination IPv6 addresses of messages are also included.

Define suffix to append at the end of logs.
