Scripts and Checks ================== End users can extend the ntopng functionalities by creating scripts which allow them, for example, to trigger custom alerts or provide new data visualizations in ntopng. Scripts can contain different resources, for example `localization files`_, `custom pages`_ and `Checks`_. The `Checks`_ are used to implement logic such as the triggering of alerts when a certain even occurs. For an extensive discussion on how to develop new scripts check out the `scripts section`_ . .. _`Scripts section`: ../scripts/overview.html .. _`localization files`: ../scripts/localization.html .. _`custom pages`: ../scripts/custom_pages.html .. _`alert definitions`: ../scripts/alert_definitions.html .. _`Checks`: ../scripts/checks.html
