DESCRIPTION

Net::GrowthForecast is a client library for GrowthForecast JSON API. This supports GET/LIST/EDIT/ADD/REMOVE simple graphs and complex graphs.

USE GrowthForecast v0.33 or later

METHODS

my $gf = Net::GrowthForecast->new( %opts )

Create client instance for growhtforecast. All options are optional.

host: Your growthforecast hostname as string (default: 'localhost')

port: Port number (default: 5125)

prefix: URI path prefix string if you use reverse-proxy and mounts growthforecast on sub directory. (default: none)

timeout: HTTP timeout seconds (default: 30)

debug: Debug mode for HTTP request/response (default: false)

$gf->post( $service, $section, $name, $value, %opts )

Update graph (specified by service, section, name) number value as $value. %opts (optional) are:

mode: 'gauge', 'count', 'modified', or 'derive' (default: 'gauge')

color: update graph color like '#FF8800' (default: not changed, or random (when creation))

$gf->graphs()

Return arrayref of hashref, includes list of basic graph, like:

    [ { id => 1, service_name => '...', section_name => '...', graph_name => '...' }, { id => 2, ... }, ... ]

$gf->complexes()

Return arrayref of hashref, includes list of complex graph, like:

    [ { id => 1, service_name => '...', section_name => '...', graph_name => '...' }, { id => 2, ... }, ... ]

You should take care that 'id' of complex graph and basic graph is not unique - basic graph id '1' and complex graph id '1' may also exists at the same time. 'service/section/graph' name is unique key of graphs.

$gf->graph( $graph_id )

Return graph detail as hashref like:

    {
      id => 13,
      
      service_name => 'example',
      section_name => 'test',
      graph_name   => 'sample1',
      
      complex => 0,
      
      description => '',
      mode    => 'gauge',
      sort    => 0,
      color   => '#ff0000',
      gmode   => 'gauge',
      type    => 'LINE2',
      ulimit  => 1000000000,
      llimit  => -1000000000,
      stype   => 'AREA',
      sulimit => 100000,
      sllimit => -100000,
      adjust  => '*',
      adjustval => 1,
      unit    => '',
      
      number  => 0,
      data    => [],
      created_at => '2012/12/31 10:57:46',
      updated_at => '2012/12/31 10:57:46'
    }

$gf->complex( $complex_id )

Return graph detail as hashref like:

    {
      id => 2,
      
      section_name => 'test',
      service_name => 'example',
      graph_name   => 'sample2',
      
      complex  => 1,
      
      data => [
                {
                  gmode    => 'gauge',
                  graph_id => 1,
                  stack    => \0,
                  type     => 'LINE1'
                },
                {
                  gmode    => 'gauge',
                  graph_id => 45,
                  stack    => 1,
                  type     => 'LINE1'
                },
                {
                  gmode    => 'gauge',
                  graph_id => 46,
                  stack    => 1,
                  type     => 'LINE1'
                }
              ],
      
      description => 'testing now',
      sort  => 19,
      sumup => 1,
      
      number => 0,
      created_at => '2012/12/31 11:32:22',
      updated_at => '2012/12/31 11:32:22'
    }

$gf->all()

Returns arrayref of both detail basic graph hashref and detail complex graph hashref.

$gf->tree()

Returns hashref, contains serice - section - graph_name as directory tree, for both of graph and complex. Value of $tree->{$service}->{$section}->{$graph_name} is detail graph infomation.

$gf->by_name( $service, $section, $graph_name )

Returns detail graph info for complex or not. (Relatively heavy: you should use cached $gf->tree() result for many queries)

$gf->edit( $graph || $complex )

Update graph data with specified object's values. Returns success or not.

$gf->delete( $graph || $complex )

Delete graph data with specified object's id. Returns success or not.

$gf->add( $spec )

Add graph or complex graph, with specified detail graph object's spec. 'id' is ignored if exits. Request will fail with non-unique'service/section/graph' values.

Returns success or not.

$gf->add_graph( $service, $section, $graph_name, $init_value [, $color, $mode] )

Add basic graph with specified service/section/name and value. 'color' and 'mode' are optional.

mode: You should specify $mode at graph creation if you want 'derive' graph.

Returns success or not.

$gf->add_complex( $service, $section, $graph_name, $description, $sumup, $sort, $type, $gmode, $stack, @data_graph_ids )

Add complex graph with specified options. All arguments are reequired, and type/gmode/stack will used for all sub data graphs. Returns success or not.
