Telegram logger for long experiments.

First, install the dependencies:

• Redis
• Redis client for python
• Telethon
• Sqlite (required by Telethon)

Get your Telegram API working:

• Get API ID and API Hash from Telegram
• Get a bot token from BotFather
• Start your bot in your Telegram. Bots cannot start conversations, so this step is necessary.

Set the appropriate environment variables in ~/.bashrc:

export TELELOG_DIR="YOUR_PATH_TO_TELELOG"
export PATH=$TELELOG_DIR:$PATH
export TELEGRAM_API_ID="YOUR API ID"
export TELEGRAM_API_HASH="YOUR API HASH"
export TELEGRAM_BOT_TOKEN="YOUR BOT TOKEN ACQUIRED FROM BOTFATHER"
export TELEGRAM_RECIPIENT="YOUR RECIPIENT'S ID IN TELEGRAM"
export TELEGRAM_REDIS_CHANNEL="telegram_queue"

Make sure the redis server is running:

redis-cli ping

Set the correct permissions:

chmod +x init_telegram_client.py 
chmod +x telelog_worker.py
chmod +x telelog
chmod +w init_telegram_client.py
chmod +w telelog_worker.py

Initialize your telegram session (You will be asked to provide your phone number, password, and a verification code):

python3 init_telegram_client.py

Make sure the telelog worker is running (This step can be skipped since the telelog command will run the worker if it's not already running):

python3 telelog_worker.py &

You might want to use taskset to bind it to a specific processor. In this example, it is binded to the last one.

taskset -c $((`nproc` - 1)) python3 telelog_worker.py & 

Netflix and log :)

From the command line:

telelog "Hello world"

From a python script:

import os
import redis

r = redis.Redis(host='localhost', port=6379, db=0)

channel_name = os.getenv("TELEGRAM_REDIS_CHANNEL")
r.publish(channel_name, "Hello world")

From a python script with proper logging setup:

from telelog_handler import TelelogHandler
import logging 
import os 

logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s')
telelog_handler = TelelogHandler(channel=os.getenv("TELEGRAM_REDIS_CHANNEL"))
telelog_handler.setFormatter(logging.Formatter('%(name)s - %(asctime)s - %(levelname)s\n`%(message)s`'))
log = logging.getLogger(__name__)
log.addHandler(telelog_handler)

log.info("Hello world")
