    • Properties
      The Properties field describes the type of information that is returned by this counter. Properties include the following types:
      • percent for values that are a percentage value, such as cpu_busy
      • rate for values that describe a value per time, such as disk_data_read
      • average for values that return an average, such as write_latency
      • raw for simple values that have no type, such as num_processors
    • Unit
      The Unit field describes how value returned by this counter can be interpreted. The Unit field can be in one of the following groups of values:
      • percent for counters with a Properties of percent
      • The unit per time period for counters with a Properties of rate, such as kb_per_sec or per_sec.
