NAME Cisco::ACI - Perl interface to the Cisco APIC API. =head2 SYNOPSIS This module provides a Perl interface to Cisco APIC API. use Cisco::ACI; my $aci = Cisco::ACI->new( username=> $username, password=> $password, server => $server ); # Required! $aci->login; # Get the leaf nodes of the pod as an array of # Cisco::ACI::FabricNode objects. my @leafs = $aci->get_leafs; # Same but for spines (both leaf and spine nodes # are Cisco::ACI::FabricNode objects). my @spines = $aci->get_spines; # Or, get a leaf by ID - still returns a # Cisco::ACI::FabricNode object. my $leaf = $aci->(101); # Do some interesting stuff with it. # Like, get the 5min measurements of policy CAM (TCAM) usage # as a Cisco::ACI::Eqptcapacity::PolUsage object. my $pol_usage = $leaf->PolUsage( '5min' ); # So now we can calculate the policy CAM utilisation my $pol_utilisation = ( $pol_usage->polUsageCum / $pol_usage->polUsageCapCum ) * 100; # Or get the number of faults present my $faults = $leaf->fault_counts; printf( 'Node %s has %d Minor, %d Major, %d Warning, and %d Critical faults\n', $leaf->name, $faults->minor, $faults->maj, $faults->warn, $faults->crit );

    # And much more... 
=head2 METHODS
=head3 new ( %ARGS )
Constructor.  Creates a new Cisco::ACI object.  This method accepts three mandatory
and two optional named parameters:
=over 4
=item B<username>
The username with which to connect to the Cisco APIC API.
=item B<password>
The password with which to connect to the Cisco APIC API.
=item B<server>
The resolvable hostname of the Cisco ACI APIC to connect to.
=item B<port>
The TCP port on which to connect to the Cisco ACI APIC, if not specified
this parameter will default to a value of 443, which is probably what you want.
=item B<proto>
The protocol to use when connecting to the Cisco ACI APIC, if not specified
this parameter will default to a value of 'https', which is probably what you want.
=back
=head3 bd_constraint ()
Returns the maximum configurable number Bridge Domains (fvBD) in the fabric.
=head3 bd_count ()
Returns the number of configured Bridge Domains (fvBD) in the fabric.
=head3 cluster_appliances ()
Returns all APICs in the cluster as an array of L<Cisco::ACI::Infra::WiNode>
objects.  Note that APICs are also separately represented as devices of type 
L<Cisco::ACI::FabricNode> within the Cisco APIC MO (see method B<controllers()>).
=head3 cluster_standby_appliances ()
Returns all standby APICs in the cluster as an array of L<Cisco::ACI::Infra::SnNode>
objects.
=head3 concrete_devices_constraint ()
Returns the maximum configurable number concrete devices (vnsCDev) in the fabric.
=head3 concrete_devices_count ()
Returns the number of configured concrete devices (vnsCDev) in the fabric.
=head3 contract_constraint ()
Returns the maximum configurable number contracts (vzBrCP) in the fabric.
=head3 contract_count ()
Returns the number of configured contracts (vzBrCP) in the fabric.
=head3 controllers ()
Returns all APICs in the cluster as an array of L<Cisco::ACI::FabricNode> objects.
Note that APICs are also separately represented as devices of type L<Cisco::ACI::Infra::WiNode> 
within the Cisco APIC MO (see method B<cluster_appliances()>).
=head3 controller ( $ID )
Returns the APIC identified by the $ID parameter as a L<Cisco::ACI::FabricNode>
object.  Note that APICs are numbered sequentially starting from 1.
=head3 ep_constraint ()
Returns the maximum configurable number end points (fvCEp) in the fabric.
=head3 ep_count ()
Returns the number of configured end points (fvCEp) in the fabric.
=head3 epg_constraint ()
Returns the maximum configurable number end point groups (fvAEPg) in the fabric.
=head3 epg_count ()
Returns the number of configured end point groups (fvAEPg) in the fabric.
=head3 fabric_links ()
Returns all fabric links as an array of L<Cisco::ACI::Fabric::Link> objects.
=head3 faults ()
Returns all fabric faults as an array of L<Cisco::ACI::Fault::Inst> objects.
=head3 fexs ()
Returns all fabric extendeds (fexs) as an array of L<Cisco::ACI::Eqpt::ExtCh> 
objects.
=head3 get_capability_rules ()
Returns all capacity rules as an array of L<Cisco::ACI::FvcapRule> objects.
=head3 health ()
Returns the fabric health as an array of L<Cisco::ACI::Health::Inst> objects.
=head3 leaf ( $ID )
Returns the leaf node identified the the B<$ID> parameter as a
L<Cisco::ACI::FabricNode> object.
=head3 leafs ()
Returns all leaf nodes as an array of L<Cisco::ACI::FabricNode> objects.
=head3 login ()
Perfoms a login to the ACI APIC API - note that merely calling the constructor
does not automatically log you into the fabric.  Rather you are required to invoke
this method to do so.
=head3 overallHealth5min ()
Returns the overall health of the fabric for the previous fivce minute interval as
an L<Cisco::ACI::Stats::Curr::OverallHealth> object.
=head3 service_graph_constraint ()
Returns the maximum configurable number of service graphs (vnsGraphInst) in the fabric.
=head3 service_graph_count ()
Returns the number of configured service graphs (vnsGraphInst) in the fabric.
=head3 spine ( $ID )
Returns the spine node identified the the B<$ID> parameter as a
L<Cisco::ACI::FabricNode> object.
=head3 spines ()
Returns all spine nodes as an array of L<Cisco::ACI::FabricNode> objects.
=head3 tenant ( $TENANT )
Returns the tenant identified by the $TENANT parameter as a L<Cisco::ACI:Tenant>
object.
=head3 tenant_constraint ()
Returns the maximum configurable number of tenant (fvTenant) in the fabric.
=head3 tenant_count ()
Returns the number of configured tenants (fvTenant) in the fabric.
=head3 vrf_constraint ()
Returns the maximum configurable number of VRFs (fvCtx) in the fabric.
=head3 vrf_count ()
