    'A path group is a named collection of DBus object

    on the referencing directive.

    Within a single configuration file path group names
    must be unique.  The same name can appear in multiple
    configuration files; however, the referencing directive
    will only search for the group in the same configuration

    in a similar fashion as the property watch directive.

    The journal callback logs the specified message to the systemd journal
    with the specified severity.

    Additionally, the journal callback will add to the journal key value
    pair metadata for each property in the specified property group with
    the key being the property element metadata and the value being the

    'Callbacks groups are simply named collections of other callbacks.
    Configuration file directives can only refer to a single callback.
    Through use of a group, these configuration file directives can
    refer to more than one callback.

    For example for a given event, one may wish to trace multiple
    messages to the systemd journal.  The journal callback does not
    support tracing multiple messages.  To do that, define a callback
    group composed of multiple journal callbacks.

    This example callback group only has one member.  To add more, add
    additional callbacks to the members element.'

- name: example count condition
  description: >
    'Conditions or conditional callbacks apply a test prior to invoking
    the callback function.

    All conditional callbacks must specify the callback to issue if
    the condition evaulates.

    The count condition applies the op comparison operator to the value of each
    property in the specified groups.  It then counts the number of properties
    that pass the comparison, and applies another comparison on the result
    against the specified bound.

    For example, a callback that requires at least three temperature sensors
    in the group to be higher than 115 degrees might use a count condition
    with an op of >, a count op of >=, a bound of 115, and a countbound of 3.'
