=head1 NAME

NACL::CS::SystemHealthConfig

=head1 DESCRIPTION

C<NACL::CS::SystemHealthConfig> is a derived class of
L<NACL::CS::ComponentState::ONTAP|lib-NACL-CS-ComponentState-ONTAP-pm>. It represents the
state of an ONTAP SystemHealthConfig.  A related class is
L<NACL::C::SystemHealthConfig|lib-NACL-C-SystemHealthConfig-pm>, which represents access
to an ONTAP SystemHealthConfig.

=head1 ATTRIBUTES

The individual pieces of data that are part of the  state of the SystemHealthConfig
element are the attributes of the SystemHealthConfig ComponentState.

=head2 fetch

    my $SystemHealthConfig_state   = NACL::CS::SystemHealthConfig->fetch(command_interface => $ci, ...);
	my @SystemHealthConfig_states = NACL::CS::SystemHealthConfig->fetch(command_interface => $ci, ...);

(Class method)
Discovers which elements are present and returns their state in ComponentState
objects. Called in scalar context it returns only one state object, in list
context it returns all state objects.
See L<NACL::CS::ComponentState|lib-NACL-CS-ComponentState-pm/fetch> for a
more detailed description along with a complete explanation of the options
it accepts.

=item Exceptions

=over

=item C<NACL::Exceptions::NoElementsFound>

When there are no elements matching the query specified or elements of that type
doesn't exist, then this exception will be thrown.
