docs: def build_counter_list(counter_list):
      r'''
      Create a list of Counter objects to be used in the pdh query
  
      Args:
          counter_list (list):
              A list of tuples containing counter information. Each tuple should
              contain the object, instance, and counter name. For example, to
              get the ``% Processor Time`` counter for all Processors on the
              system (``\Processor(*)\% Processor Time``) you would pass a tuple
              like this:
  
              ```
              counter_list = [('Processor', '*', '% Processor Time')]
              ```
  
              If there is no ``instance`` for the counter, pass ``None``
  
              Multiple counters can be passed like so:
  
              ```
              counter_list = [('Processor', '*', '% Processor Time'),
                              ('System', None, 'Context Switches/sec')]
              ```
  
              .. note::
                  Invalid counters are ignored
  
      Returns:
          list: A list of Counter objects
      '''
      counters = []
      index = 0
      for obj, instance, counter_name in counter_list:
          try:
              counter = Counter.build_counter(obj, instance, index, counter_name)
              index += 1
              counters.append(counter)
          except CommandExecutionError as exc:
              # Not a valid counter
              log.debug(exc.strerror)
              continue
      return counters
