lisa.trace.DmesgCollector

class lisa.trace.DmesgCollector(target, *, empty_buffer=False, facility='kern', level='debug', output_path=None, parse_error=None)

Bases: CollectorBase

Wrapper around devlib.collector.dmesg.DmesgCollector.

It installs the dmesg tool automatically on the target upon creation, so we know what version is being is used.

Attributes

LOG_LEVELS
NAME	Name of the collector class.
TOOLS	Sequence of tools to install on the target when using the collector.

Properties

logger inherited

Convenience short-hand for self.get_logger().

Methods

__enter__() inherited
__exit__() inherited
__getattr__ inherited	Delegate attribute lookup to a private attribute.
get_data() inherited	Similar to devlib.collector.CollectorBase.get_data() but takes the path directly as a parameter in order to disallow representing an invalid state where no path has been set.
get_logger() inherited	Provides a logging.Logger named after cls.
log_locals() inherited	Debugging aid: log the local variables of the calling function.

DmesgCollector.LOG_LEVELS = ['emerg', 'alert', 'crit', 'err', 'warn', 'notice', 'info', 'debug']
