How to create Telegram bot and use it with Roxy-WI
Telegram is a free, cross-platform, cloud-based instant messaging, video calling, and VoIP service. It was initially launched for iOS on August 14, 2013, in Russia and is currently based in Dubai. OOfficial Telegram client apps are available for Android, iOS, Windows, macOS, and Linux, as well as for the now-discontinued Windows Phone. Additionally, there is an official web interface and numerous unofficial clients. All of Telegram's official apps are open source.
Telegram offers end-to-end encrypted calls and optional end-to-end encrypted "secret" chats between two online users on smartphone clients, while cloud chats utilize client-server/server-client encryption. Users can send text and voice messages, animated stickers, and share an unlimited number of images, documents (up to 2GB per file), user locations, contacts, and music. As of April 2020, Telegram has reached 400 million monthly active users.
Checker is a service that monitors HAProxy, NGINX, Apache and Keepalived services as well as HAProxy backends. Checker sends a notification via Telegram, Slack, email, PagerDuty and/or Mattermost when a backend or service is down.
