get_cluster_list

Gets a list of the cluster names.

get_failover_mode

Gets the current fail-over mode that the device is running in.

get_failover_state

save_configuration ($filename)

$ic->save_configuration('backup.ucs');

# is equivalent to

$ic->save_configuration('backup');

# Not specifying a filename will use today's date in the
# format YYYYMMDD as the filename.

$ic->save_configuration();

# is equivalent to

$ic->save_configuration('today');

Saves the current configurations on the target device.

This method takes a single optional parameter; the filename to which the configuration should be saved. The file extension .ucs will be suffixed to the filename if missing from the supplied filename.

Specifying no optional filename parameter or using the filename today will use the current date as the filename of the saved configuration file in the format YYYYMMDD.

get_vs_list

my @virtuals	= $ic->get_vs_list();

Returns an array of all defined virtual servers.

get_vs_destination ($virtual_server)

my $destination	= $ic->get_vs_destination($vs);

Returns the destination of the specified virtual server in the form v4_ip_address%route_domain:port.

get_vs_enabled_state ($virtual_server)

print "Virtual server $vs is in state ",$ic->get_vs_enabled_state($vs),"\n";

Return the enabled state of the specified virtual virtual server.

get_vs_all_statistics

Returns the traffic statistics for all configured virtual servers. The statistics are returned as VirtualServerStatistics struct hence this method is useful where access to raw statistical data is required.

For parsed statistic data, see get_vs_statistics_stringified.

For specific information regarding data and units of measurement for statistics methods, please see the Notes section.

get_vs_statistics ($virtual_server)

my $statistics = $ic->get_vs_statistics($vs);

Returns all statistics for the specified virtual server as a VirtualServerStatistics object. Consider using get_vs_statistics_stringified for accessing virtual server statistics in a pre-parsed hash structure.

For specific information regarding data and units of measurement for statistics methods, please see the Notes section.

get_vs_statistics_stringified ($virtual_server)

my $statistics = $ic->get_vs_statistics_stringified($vs);

foreach (sort keys %{$stats{stats}}) {
	print "$_: $stats{stats}{$_}\n";
}

Returns all statistics for the specified virtual server as a multidimensional hash (hash of hashes). The hash has the following structure:

{
	timestamp	=> 'yyyy-mm-dd-hh-mm-ss',
	stats		=> {
				statistic_1	=> value,
				statistic_2	=> value,
				...
				statistic_n	=> value
			}
}

This function accepts a single parameter; the virtual server for which the statistics are to be returned.

For specific information regarding data and units of measurement for statistics methods, please see the Notes section.

get_default_pool_name

print "Virtual Server: $virtual_server\nDefault Pool: ",

		print "\t$member\n";
	}
}

Returns a list of the pool members for the specified pool. This method takes one mandatory parameter; the name of the pool.

Pool member are returned in the format IP_address:service_port.

get_node_list

print join "\n", ($ic->get_node_list());

Returns a list of all configured nodes in the target system.

Nodes are returned as IP addresses.

get_screen_name ($node)

foreach ($ic->get_node_list()) {
	print "Node: $_ (" . $ic->get_screen_name($_) . ")\n";
}

Retuns the screen name of the specified node.

get_node_status ($node)

$ic->get_node_status(

				...
				statistic_n	=> value
			}
}

get_event_subscription

Returns all registered event subscriptions.

get_subscription_list

This method is an analog of get_event_subscription

create_subscription_list (%args)

my $subscription = $ic->create_subscription_list (
					name				=> 'my_subscription_name',
					url				=> 'http://company.com/my/eventnotification/endpoint,
					username			=> 'username',
					password			=> 'password',
					ttl				=> -1,
					min_events_per_timeslice	=> 10,
					max_timeslice			=> 10
				);

Creates an event subscription with the target system. This method requires the following parameters:

name: A user-friendly name for the subscription.
url: The target URL endpoint for the event notification interface to send event notifications.
username: The basic authentication username required to access the URL endpoint.
password: The basic authentication password required to access the URL endpoint.
ttl: The time to live (in seconds) for this subscription. After the ttl is reached, the subscription will be removed from the system. A value of -1 indicates an infinite life time.
min_events_per_timeslice: The minimum number of events needed to trigger a notification. If this value is 50, then this means that when 50 events are queued up they will be sent to the notification endpoint no matter what the max_timeslice is set to.
max_timeslice: This maximum time to wait (in seconds) before event notifications are sent to the notification endpoint. If this value is 30, then after 30 seconds a notification will be sent with the events in the subscription queue.

NOTES

iControl Compatibility

This module was written for version 10.x and less of BIGIP. The iControl API has changed significantly with the most recent version (11) and some features may not exist in older version (9.x).

Statistic Methods

Within iControl, statistical values are a 64-bit unsigned integer represented as a Common::ULong64 object. The ULong64 object is a stuct of two 32-bit values. This representation is used as there is no native support for the encoding of 64-bit numbers in SOAP.

The ULong object has the following structure;

({
	STATISTIC_NAME	=> {
			high	=> long
			low	=> long
		}
}, bless Common::ULong64)

Where high is the unsigned 32-bit integer value of the high-order portion of the measured value and low is the unsigned 32-bit integer value of the low-order portion of the measured value.

In non-stringified statistic methods, these return values are ULong64 objects as returned by the iControl API. In stringified statistic method calls, the values are processed on the client side into a local 64-bit representation of the value using the following form.

$value = ($high<<32)|$low;

Stringified method calls are guaranteed to return a correct localised 64-bit representation of the value.

It is the callers responsibility to convert the ULong struct for all other non-stringified statistic method calls.
