=head1 NAME

NACL::CS::SystemHealthSubsystem Component.

=head1 DESCRIPTION

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

=head1 ATTRIBUTES

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

Additionally, the command_interface used to obtain the ComponentState object is
also an attribute of the object. This makes it easier to obtain the component
object corresponding to the CS object, using
L<get_component_instance|lib-NACL-CS-ComponentState-pm/get_component_instance>.

=over

=item command_interface

The command_interface with which the CS object was obtained. (Available in
all CS objects regardless of requested_fields and the mode/interface)

=item C<< init_state >>

Initialization State, possible value(s) are
Invalid,Initailizing,Initialized,Starting_Discovery,Starting_Re-Discovery,Discovery_Done_Partially,Discovery_Done

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

For "requested_fields", "filter" and Output mapping:

 <diagnosis-subsystem-config-info>
    <init-state>$value</init-state>
 </diagnosis-subsystem-config-info>

=item C<< outstanding_alert_count >>

Number of Outstanding Alerts

Filled in for CMode CLI/ZAPI.

Maps to:

For "requested_fields", "filter" and Output mapping:

 <diagnosis-subsystem-config-info>
    <outstanding-alert-count>$value</outstanding-alert-count>
 </diagnosis-subsystem-config-info>

=item C<< subsystem >>

Subsystem

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

For "requested_fields", "filter" and Output mapping:

 <diagnosis-subsystem-config-info>
    <subsystem>$value</subsystem>
 </diagnosis-subsystem-config-info>

=item C<< suppressed_alert_count >>

Number of Suppressed Alerts

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

For "requested_fields", "filter" and Output mapping:

 <diagnosis-subsystem-config-info>
    <suppressed-alert-count>$value</suppressed-alert-count>
 </diagnosis-subsystem-config-info>

=item C<< health >>

Health, possible value(s) are

Ok,Ok_with_suppressed,degraded,unreachable,unknown

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

For "requested_fields", "filter" and Output mapping:

 <diagnosis-subsystem-config-info>
    <health>$value</health>
 </diagnosis-subsystem-config-info>

    my $SystemHealthSubsystem_state  = NACL::CS::SystemHealthSubsystem->fetch(command_interface => $ci, ...);
	my @SystemHealthSubsystem_states = NACL::CS::SystemHealthSubsystem->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.

Supports CMode CLI/ZAPI APISet.

Invokes 'diagnosis-subsystem-config-get-iter' API for CMode ZAPI.

=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.
