DVOR & DME Building Power Network Monitoring Labuan Bajo Sub-Branch Uses Telegram API Bot Notifications Through Netwatch Mikrotik

Abstract

The development of information technology in tandem with the flow of globalization has brought major changes to the way humans access and disseminate information. One of the impacts is to make the internet a primary need, both in the world of work, education, and government. Easy access and instant communication are indispensable in the management of information systems, especially in network infrastructure monitoring. Telegram is one of the cloud-based instant messaging applications that is open source. The app not only offers basic communication features, but it also supports the development of advanced functions through the Telegram Bot API. This feature allows developers to create automation systems, including in terms of network monitoring. On the other hand, Netwatch is one of the features of the Mikrotik RB2011UiAS-RM device that functions to monitor network connections to certain destination addresses on a regular basis. When a connection interruption occurs, Netwatch may take automated actions, such as sending notifications or executing certain scripts. By combining Netwatch and Telegram's Bot API, a network monitoring system can be built to provide real-time notifications to network administrators. One of the implementations of this system was carried out at the DVOR & DME Building of the Labuan Bajo Sub-Branch which is located on a hill, about 500 meters to the north of the Tower Building. Access to the location is quite difficult because it is not equipped with street lighting, has rocky and steep terrain, and can only be passed by two-wheeled vehicles, especially during the rainy season. In these conditions, a network monitoring system that is able to provide up/down internet status information directly through Telegram is very important. This notification can be an indicator of whether the power grid at the location is still active or has been out, so that technicians can respond faster without having to check directly to the location.
