Requests

import requests

PING = "https://vivere.dev/p/<monitor-id>"

def ping(suffix="", body=None):
    try:
        requests.post(f"{PING}{suffix}", data=body, timeout=10)
    except requests.RequestException:
        pass  # never let monitoring break the job

A decorator for scheduled functions

import functools, traceback

def monitored(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        ping("/start")
        try:
            result = func(*args, **kwargs)
        except Exception:
            ping("/fail", traceback.format_exc()[-16000:])
            raise
        ping("", f"{func.__name__} ok")
        return result
    return wrapper

@monitored
def nightly_etl():
    ...
