ntopng core is extensible by means of plugins. Users and programmers with basic scripting skills are able to extend ntopng to implement custom features.
Plugins offer the following capabilities.
Monitoring an Analysis¶
Plugins provide mechanisms to watch and analyze network traffic, flows, hosts and other network elements. They also enable the monitoring of the health and status of ntopng, as well as of the system on top of which ntopng is running.
Plugins enable the generation of custom alerts. Generated alerts appear within the ntopng web GUI and are propagated towards external alert endpoints.
Plugins enable the creation of custom pages. Custom pages are shown within the ntopng web GUI and have links in the menu.
Plugins enable the generation of timeseries for custom metrics. Points of custom metrics are written from inside the plugin. ntopng charts show custom metrics points over time.
