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}

class insights.parsers.multicast_querier.MulticastQuerier(context, extra_bad_lines=None)

Bases: insights.core.CommandParser

Parse the output of the command:

find /sys/devices/virtual/net/ -name multicast_querier -print -exec cat {} ;

Get a dictionary of “bridge interface” and the value of the parameter “multicast_querier”

parse_content(content)

This method must be implemented by classes based on this class.
