Note

Because /var/log/messages timestamps by default have no year, the year of the logs will be inferred from the year in your timestamp. This will also work around December/January crossovers.

Examples

>>> Messages.filters.append('wrapper')
>>> Messages.token_scan('daemon_start', 'Wrapper Started as Daemon')
>>> msgs = shared[Messages]
>>> len(msgs.lines)
>>> wrapper_msgs = msgs.get('wrapper') # Can only rely on lines filtered being present
>>> wrapper_msgs[0]
