Question

Is it possible to add new tab to the tabs in Admin Dashboard

Answer 1

Yes it is possible to add the new tabs in Admin dashboard.

If you check the file:

vendor/magento/module-backend/Block/Dashboard/Grids.php

This is the block file where you can add the tabs. Here you need to point to proper controller to show the data for the tab.

protected function _prepareLayout()
    {
        // load this active tab statically
        $this->addTab(
            'ordered_products',
            [
                'label' => __('Bestsellers'),
                'content' => $this->getLayout()->createBlock(
                    'Magento\Backend\Block\Dashboard\Tab\Products\Ordered'
                )->toHtml(),
                'active' => true
            ]
        );

        // load other tabs with ajax
        $this->addTab(
            'reviewed_products',
            [
                'label' => __('Most Viewed Products'),
                'url' => $this->getUrl('adminhtml/*/productsViewed', ['_current' => true]),
                'class' => 'ajax'
            ]
        );

        $this->addTab(
            'new_customers',
            [
                'label' => __('New Customers'),
                'url' => $this->getUrl('adminhtml/*/customersNewest', ['_current' => true]),
                'class' => 'ajax'
            ]
        );

        $this->addTab(
            'customers',
            [
                'label' => __('Customers'),
                'url' => $this->getUrl('adminhtml/*/customersMost', ['_current' => true]),
                'class' => 'ajax'
            ]
        );

        return parent::_prepareLayout();
    }

You can call addTab menthod to to add the new tab on the admin dashboard.

The proper way of doing it to not modify the core files and override the module.
