NAME

Net::AppDynamics::REST - AppDynamics AnyEvent Friendly REST Client

SYNOPSIS

  use Net::AppDynamics::REST;

  my $obj=Net::AppDynamics::REST->new(PASS=>'password',USER=>'Username',SERVER=>'SERVERNAME');

  # to get a list of applications in a non blocking context
  my $resut=$obj->list_applications;

  # get a list of applications in a non blocking context
  use AnyEvent;

  $obj->que_list_applications(sub {
    my ($self,$id,$result,$request,$response)=@_;
  });
  $ojb->agent->run_next;
  AnyEvent::Loop::run;

DESCRIPTION

Appdynamics AnyEvent friendly Rest client.

OO Declarations

Required

  USER: Sets the user appd
  PASS: Sets the password
  SERVER: Sets the server

Optional

  logger: sets the logging object
  CUSTOMER: default customer1
  PORT: default 8090
  PROTO: default http
  cache_max_age: how long to keep the cache for in seconds
    default value is 3600
  agent: Gets/Sets the AnyEvent::HTTP::MultiGet object we will use

For Internal use

  data_cache: Data structure used to cache object resolion

Moo::Roles

This module makes use of the following roles: HTTP::MultiGet::Role, Log::LogMethods and Data::Result::Moo

OO Methods

  • my $url=$self->base_url

    Creates the base url for a request.

  • my $request=$self->create_get($path,%args);

    Create a request object for $path with the required arguments

  • my $result=$self->new_true({qw( some data )});

    Returns a new true Data::Result object.

  • my $result=$self->new_false("why this failed")

    Returns a new false Data::Result object

NonBlocking interfaces

All methods with a prefix of que_xxx are considered non blocking interfaces.

Default Callback arguments:

  my $code=sub {
    # 0: this Net::AppDynamics::REST Object
    # 1: id, for internal use
    # 2: Data::Result Final object ( if failed, it will say why it failed )
    # 3: HTTP::Request Last Object|undef
    # 4: HTTP::Response Last Object|undef
    my ($self,$id,$result,$request,$response)=@_;
  };

Blocking Interfaces

All interfaces that are prefixed with que_xxx have a corisponding blocking method that is simply the xxx portion of the method name.

Example Non Blocking version of que_list_applicatinos:

  my $result->list_applicatinos();

When called without the que context the methods provides the more traditional blocking style inteface. When called in a blocking context only the Data::Result Object is returned.

Application Model API

  • my $id=$self->que_list_applicatinos

    Queues a requst to fetch the list of all applications

  • my $id=$self->que_list_tiers($cb,$application);

    Queues a request to fetch the list of tiers within a given application

  • my $id=$self->que_list_tiers($cb,$application,$tier);

    Ques a request for the details of the application tier

  • my $id=$self->que_list_business_transactions($cb,$application)

    Queues a request to fetch the list of business transactions for a given application

  • my $id=$self->que_list_nodes($cb,$application)

    Ques a request to all the nodes in a given application

  • my $id=$self->que_list_nodes($cb,$application,$node)

    Queues a request to list the details of a node in a given tier

  • my $id=$self->que_list_backends($cb,$application)

    Queues a request to list the backends for a given application

  • my $id=$self->que_walk_all($cb)

    Queues a request to walk everything.. $cb arguments are different in this caes, $cb is called with the following arguments. Keep in mind this walks every single object in mass and up to 20 requests are run at a time ( by default ), so this can put a strain on your controler if run too often.

      my $cb=sub {
        # 0: this Net::AppDynamics::REST Object
        # 1: id, for internal use
        # 2: Data::Result Final object ( if failed, it will say why it failed )
        # 3: HTTP::Request Last Object|undef
        # 4: HTTP::Response Last Object|undef
        # 5: method ( wich method this result set is for ) 
        # 6: application ( undef the method is list_applications )
        my ($self,$id,$result,$request,$response,$method,$application)=@_;
      };

    The structure of $result->get_data when true contains the following anonymous hash.

    Objects are listed by ids ids: Anonymous hash of ids to object refrerences

      # keys used to map names to object ids
      applications, business_transactions, tiers, nodes
        Each element contains an anonymous hash of of an array refres
          Each element in the array ref refres back to an ids object.

Alert and Respond API

  • my $id=$self->que_health_rule_violations($cb,$app,%args);

    Queues a health rule violation lookup

    Example ( defaults if no arguments are passed ):

      my $id=$self->que_health_rule_violations($cb,"PRODUCTION",'time-range-type'=>'BEFORE_NOW','duration-in-mins'=>15);

    For more details, please see: https://docs.appdynamics.com/display/PRO43/Alert+and+Respond+API#AlertandRespondAPI-RetrieveAllHealthRuleViolationsinaBusinessApplication

  • my $id=$self->que_resolve($cb,$type,$name);

    Used to resolve tiers, nodes, business_transactions, and applications to thier application's id.

     cb:  standard callback
     type: String representing the typpe of object to resolve (tiers|nodes|business_transactions|applications);
     name: name to be resolved

    Uses the internal cache to resolve the object, if the internal cache is out of date or empty the cache will be refreshed.

  • my $id=$self->que_check_cache($cb);

    Queues a cache check. The resolve cache is refreshed if it is too old.

  • my $id=$self->que_find_health_rule_violations($cb,$type,$name,%args)

    Queues a a $sellf->que_health_rule_violations($internal_cb,%args)

    The result when true will cointain health rules on anything that resolved.

    See: que_health_rule_violations and que_resolve for more information

Configuration Import and Export API

This section documents the Configuration Import and Export API.

  • my $id=$self->que_export_policies($cb,$app)

    Queues the exporting of a policy

Bugs and Patches

Please report bugs and submit patches via https://rt.cpan.org

Todo

This module is pretty sparse in what it can do, this is the pre 1.0 release.. mostly becase the api is only partially implemented at best.
