SYNOPSIS

DESCRIPTION

       Module used to integrate with the REST API that Icinga2 provides.

CONSTRUCTOR

       new (FQDN, PORT, PATH, VERSION, INSECURE)
       new (FQDN, PORT, PATH, VERSION, [ INSECURE ])
           Monitoring::Icinga2::Client::REST object.

           The former calling convention with four mandatory arguments is the old one. If a port
           number is present after the Icinga host, the constructor assumes you want this form.
           The arguments are:

           •   FQDN is your Icinga monitoring host.

           •   PORT is the port the REST API runs on.

           •   PATH is the URI where to find the API, usually "/".

           •   VERSION should be set to the API version, usually 1.

           •   INSECURE is optional and makes this module skip certificate verification if set.

           The latter form treats only the FQDN as mandatory and allows all other arguments to be
           passed hash style with the following keys:

           •   "port" see above; defaults to 5665.

           •   "path" see above; defaults to "/".

           •   "version" see above; defaults to 1 and is therefore completely redundant as long
               as there is only one API version.

           •   "insecure" see above; defaults to false

           •   "cacert" The file name of a PEM-format file containing the certificate of the CA
               that issued the server's HTTPS certificate. As internal monitoring servers often
               use certs from in-house CAs, this still allows for secure peer identification
               instead of using insecure mode.

METHODS

       login (USERNAME, PASSWORD)
           Configures and validates credentials. Please note that user needs at least the
           permission "status/query". This methos does nothing if it has been called on the
           sameobject before unless "logout" was called before.

       logout
           Destroys the login session.

       login_status
           Returns a human readable login status of the current session.

       logged_in
           Returns true when logged in, otherwise returns undef.

       do_request (HTTP METHOD, URI, PARAMS, DATA)
           Performs the actual request.

           "PARAMS" is optional and can be any parameters that the Icinga API supports.

           "DATA" is optional and is a Perl data structure that will be converted to JSON.

           Returns the result in a perl reference.

       export (FULL, API_ONLY)
           Returns a Perl Data structure without unnecessary meta data. $icinga->export can only
           be called after do_request. The name of the object is stored in
           $object->{attrs}{vars}{__export_name} so that you can access if you need it, please
           note that you can't use this variable name for other things if you whis to use this
           library as it will be overwritten in the exported object.

           "FULL" is optional and if it is true, write once attributes will be included in the
           export. Objects exported with FULL set to true can be converted to json and be used
           for PUT requests, but not necessarily for POST requests.

           "API_ONLY" is optional and if it is true only objects created via the API will be
           exported.

       request_code
           Returns the last HTTP status code.

       request_status_line
           Returns the last HTTP status line.
