MulticastQuerier - command ``find /sys/devices/virtual/net/ -name multicast_querier -print -exec cat {} \;``
============================================================================================================
This module provides processing for the output of the
``find -name multicast_querier ...`` command.
Sample output of this command looks like::
/sys/devices/virtual/net/br0/bridge/multicast_querier
0
/sys/devices/virtual/net/br1/bridge/multicast_querier
1
/sys/devices/virtual/net/br2/bridge/multicast_querier
0
The ``bri_val`` method is to return a dictionary contains bridge interface and
its multicast_querier value as the parsing result::
{'br0': 0, 'br1': 1, 'br2': 0}
Examples:
>>> multicast_querier_content = '''
... /sys/devices/virtual/net/br0/bridge/multicast_querier
... 0
... /sys/devices/virtual/net/br1/bridge/multicast_querier
... 1
... /sys/devices/virtual/net/br2/bridge/multicast_querier
... 0
... '''.strip()
>>> from insights.tests import context_wrap
>>> from insights.parsers.multicast_querier import MulticastQuerier
>>> shared = {MulticastQuerier: MulticastQuerier(context_wrap(multicast_querier_content))}
>>> mq_results = MulticastQuerier(context_wrap(multicast_querier_content))
>>> mq_results.bri_val
{'br0': 0, 'br1': 1, 'br2': 0}
