This is a Python code snippet that defines a custom logging handler called `TelegramHandler`.

TelegramHandler.py

import logging

import telebot    # telebot==0.0.5
from loguru import logger  # loguru==0.7.0

bot_token = "BOT_TOKEN"
chat_id = "CHAT_ID"

# Set up the telebot client
bot = telebot.TeleBot(bot_token)

class TelegramHandler(logging.Handler):
    def __init__(self, bot, chat_id):
        super().__init__()
        self.bot = bot
        self.chat_id = chat_id

    def emit(self, record):
        log_entry = self.format(record)
        self.bot.send_message(chat_id=self.chat_id, text=log_entry)

logger.add(TelegramHandler(bot=bot, chat_id=chat_id))

@logger.catch(level=logging.ERROR)
def my_function():
    #function
    pass

the code adds an instance of the TelegramHandler class to a logger object, which is an instance of the logging.Logger class. This ensures that all log messages generated by the logger are also sent to the specified Telegram chat.

class TelegramHandler(logging.Handler):
    def __init__(self, bot, chat_id):
        super().__init__()
        self.bot = bot
        self.chat_id = chat_id

    def emit(self, record):
        log_entry = self.format(record)
        # self.bot.send_message(chat_id=self.chat_id, text=log_entry)
        raise ValueError("Serious error occurred while sending log message to Telegram")

import time
class TelegramHandler(logging.Handler):
    def __init__(self, bot, chat_id):
        super().__init__()
        self.bot = bot
        self.chat_id = chat_id

    def emit(self, record):
        log_entry = self.format(record)
        self.bot.send_message(chat_id=self.chat_id, text=log_entry)
        time.sleep(240)

class TelegramHandler(logging.Handler):
    def __init__(self, bot, chat_id):
        super().__init__()
        self.bot = bot
        self.chat_id = chat_id

    def emit(self, record):
        log_entry = self.format(record)
        if len(log_entry) > 10000:
            logger.warning("Log message is too long to send to Telegram")
            return
        self.bot.send_message(chat_id=self.chat_id, text=log_entry)



message = "A" * 10000
logger.info(message )
