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:
Search for errors in the LOKI logger
1. Log in to grafana
2. Takes a list of services from the services.txt file,
including the name of the service and the name of the person responsible
3. For each service, searches for LOKI logs with the text: error:, panic:, ERROR:, PANIC:
4. Sends the found logs with errors to the Telegram messenger
5. Repeats the search every 10 minutes

Search for errors in the database:
1. Log in to the PostgreSQL database
2. Finds .sql files in the sql folder, and executes a script in the database,
if the script returns a value, a message about this will come to the Telegram messenger,
if the script does not return lines, then everything is fine.
3. Repeats requests every 60 minutes
4. If you fill in the scripts.txt file (scripts_add.txt),
including the .sql file name and the name of the person responsible,
then the name of the person responsible will also be added.

The bot sends error logs to Telegram groups:
1. General group with all errors, all programmers.
Group ID is filled in settings.txt, TELEGRAM_CHAT_NAME=
In the Telegram group settings, you need to set the rights Group type = "Public"
2. Each programmer separately, only logs that apply to him.
Filled in the files services.txt, scripts.txt
Each programmer must add this telegram bot to his Telegram

Installation procedure:
1. Compile this repository
>make build
the telegram_loki file will appear in the bin folder

2. fill parametes in settings.txt file (or .env file)
with Grafana LOKI URL, login, password, etc.

3. Fill in the settings/services.txt file
In json format write the service name in LOKI
and the name (login) of the programmer (optional)
sample:
