=head1 NAME

Net::Fortinet::FortiManager - Fortinet FortiManager REST API client library

=head1 VERSION

version 0.003000

=head1 SYNOPSIS

    use strict;
    use warnings;
    use Net::Fortinet::FortiManager;

    my $fortimanager = Net::Fortinet::FortiManager->new(
        server      => 'https://fortimanager.example.com',
        user        => 'username',
        passwd      => '$password',
        clientattrs => {
            timeout     => 10,
        },
    );

    $fortimanager->login;

    $fortimanager->adom('adomname');

=head1 DESCRIPTION

This module is a client library for the Fortigate FortiManager JSONRPC-like
API.
Currently it is developed and tested against version 6.4.6.
All requests have the verbose parameter set to 1 to ensure that enums return
their strings instead of undocumented ids.

=head1 ATTRIBUTES

=head2 adoms

Returns a list of hashrefs containing name and uuid of all ADOMs which gets
populated by L</login>.

=head2 adom

The name of the ADOM which is used by all methods.
Defaults to 'root'.

=head1 METHODS

=head2 exec_method

Executes a method with the specified parameters.

Returns its response.

This is the lowest level method which can be used to execute every API action
that's available.
It does the http and JSONRPC error handling and extraction of the result
from the JSONRPC response.

=head2 exec_method_multi

Executes a method with multiple specified parameters.

Returns its responses.

This is also a low level method which can be used to execute multiple API
actions in a single JSONRPC call.
The only restriction of the JSONRPC API is that all actions need to use the
same method.
It does the http and JSONRPC error handling and extraction of the results
from the JSONRPC response.

=head2 login

Logs into the Fortinet FortiManager and switches to the first available ADOM
if the currently set L<adom> isn't available, for example because the user
is limited to one or more ADOMs.

=head2 logout

Logs out of the Fortinet FortiManager.

=head2 get_sys_status

Returns /sys/status.

=head2 list_adoms

Takes an optional parameter hashref.

Returns an arrayref of ADOMs.

=head2 list_adoms_by_name

Returns an arrayref of ADOMs sorted by name.

=head2 list_firewall_addresses

Returns an arrayref of firewall addresses.

=head2 get_firewall_address

=head1 TESTS

To run the live API tests the following environment variables need to be set:

=over

=item NET_FORTINET_FORTIMANAGER_HOSTNAME

=item NET_FORTINET_FORTIMANAGER_USERNAME

=item NET_FORTINET_FORTIMANAGER_PASSWORD

=item NET_FORTINET_FORTIMANAGER_POLICY

=back

Several network objects are created as well as a policy package named by the
NET_FORTINET_FORTIMANAGER_POLICY environment variable.

The test aborts if any of the objects can't be created, most likely if it
already exists.
All objects are deleted at the end of the test run, even when it aborts.
