Module - Import monitoring controller into own module

MarcoKl · August 31, 2020, 9:06am

Hello,
i have always made my own monitoring-status frontend with a customized view. My first one with direct access to the db and my second one is based in the icinga2 API. But now i want do write a module for icingaweb2. I see that some modules use a own ido backend and some uses the monitoring controller backend. i did not find a stating point to include the monitoring controller into my own module. Can somebody provide me a example to load a prefiltered list of services so that i can display this as a table.

Regards Marco

Hello @MarcoKl!

Here’s how I did it:

Icinga/icingaweb2-module-graphite/blob/e37aaf06377e5edb18e17111d7cbc6fe7b2267a6/application/controllers/GraphController.php#L15


use Icinga\Exception\Http\HttpBadRequestException;
use Icinga\Exception\Http\HttpNotFoundException;
use Icinga\Module\Graphite\Graphing\GraphingTrait;
use Icinga\Module\Graphite\Web\Controller\MonitoringAwareController;
use Icinga\Module\Graphite\Web\Widget\Graphs;
use Icinga\Module\Monitoring\Object\Host;
use Icinga\Module\Monitoring\Object\MonitoredObject;
use Icinga\Module\Monitoring\Object\Service;
use Icinga\Web\UrlParams;

class GraphController extends MonitoringAwareController
{
    use GraphingTrait;

    /**
     * The URL parameters for the graph
     *
     * @var string[]
     */
    protected $graphParamsNames = [
        'start', 'end',

<?php

namespace Icinga\Module\Graphite\Web\Controller;

use Icinga\Module\Monitoring\Controller;
use Icinga\Module\Monitoring\DataView\DataView;

abstract class MonitoringAwareController extends Controller
{
    /**
     * Restrict the given monitored object query for the currently authenticated user
     *
     * @param   DataView    $dataView
     *
     * @return  DataView                The given data view
     */
    protected function applyMonitoringRestriction(DataView $dataView)
    {

Best,

Hello AK,
i am sure that you tips are working. But i am not understanding the Zend model in total yet. I am working with rails and the schema is like zend with controller, views, helpers etc… I know how i can access in the views the values from the controllers. Now i try to make some querys with the monitoring controller to create my own view of hosts and services. I think a am not far away understanding zend

The goal is to translate my rails application for displaying custom filtered views and central controled monitors, because I want to share it with the cummunity
