Applications for sending logs with errors from the LOKI(GRAFANA) logger to the Telegram messenger

The LOKI logger has an inconvenient interface for searching errors in application logs, and no one will look there every 5 minutes - Therefore, it is necessary to automate the process of searching for errors in logs and notifying developers.

The application does:

1. Log in to grafana
2. Takes a list of services from the services.txt file
3. For each service, searches for LOKI logs with the text: error:,panic:,ERROR:,PANIC:
4. Found logs with errors are sent to the Telegram messenger
5. Repeats the search every 10 minutes

Installation procedure:

1. Compile this repository make build the telegram_loki file will appear in the bin folder
