How to add logs to a file/blob in an azure container with basicConfig

Question

I want to save the logs into a file/blob in a specific folder of an azure container using python.

I've used this code;

today = date.today()

logging.basicConfig(filename='http://127.0.0.1:10000/devstoreaccount1/cloudops-resources/logs/{}_logs.log'.format(today),
                filemode='a',
                format='%(asctime)s,%(msecs)d %(name)s %(message)s',
                datefmt='%H:%M:%S',
                level=logging.INFO,
                force=True)

But it gives an error.

Executed 'Functions.BlobTrigger' (Failed, Id=8863e10e-2cb6-4a32-8f3a-2486823740cb, Duration=30ms) [2023-04-19T11:28:58.348Z] System.Private.CoreLib: Exception while executing function: Functions.BlobTrigger. System.Private.CoreLib: Result: Failure

Can someone please help me to resolve this?

How to add logs to a file/blob in an azure container with basicConfig

Using basicConfig you can add a log file to storage account, but you are wrong in sending URL in place of PATH of the log File and this is working if i am giving local path too.

Below is the code(updated your code):

import logging
from azure.storage.blob import BlobServiceClient

c = 'DefaultEndpointsProtocol=https;AccountName=rithwik2;AccountKey=PVggwes02w==;EndpointSuffix=core.windows.net'
bsc = BlobServiceClient.from_connection_string(c)
cn = "emocon"
bn = "emolog"
cc = bsc.get_container_client(cn)
cb = cc.get_blob_client(bn)
logging.info("Hello Rithwik")
logging.basicConfig(level=logging.INFO,
                    format="%(asctime)s [%(name)s] %(message)s",
                    handlers=[logging.StreamHandler(),
                              logging.handlers.WatchedFileHandler("emolog.log")])
with open("emolog.log", "rb") as d:
    cb.upload_blob(d, overwrite=True)

enter image description here

Output:

So you can integrate the above code into your function app.
