Support logging level config of handler through configure_azure_monitor

[yli02]

Is your feature request related to a problem? Please describe.
The current logging configuration in [1] does not support to set the logging level for handler in [2], and this prevents to separate the logging to Azure and local in different levels based on logger hierarchy. For example

import logging
from azure.monitor.opentelemetry import configure_azure_monitor

app_logger = logging.getLogger("App")
app_logger.setLevel(logging.ERROR)

app_local_logger = logging.getLogger("App.local")
app_local_logger.setLevel(logging.INFO)

configure_azure_monitor(connection_string="", logger_name="app_logger")

In the application, we would like to always use logger "app_logger_local" for different level of loggings to stdout and stderr, and relying on logging hierarchy to pass logs to "app_logger". And we only would like to use Azure AppInsights to collect log with level ERROR or higher.

But this design is so far not feasible, as there is no checking of parent logger level at [3], see also [4].

Describe the solution you'd like
It would be great if a new argument could be added to [1], like logging_level to setup the logging level of the handler in [2], so we could rely on the above example code to collect loggings in different levels at different destination.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

@yli02

This scenario makes sense. A solution via environment variable in upstream OpenTelemetry Python would be able to enable this scenario and allow you to configure log level of the OpenTelemetry LoggingHandler. This however has not been implemented yet.

As a side note, you must also change your code to pass in the namespace of the parent logger you want to use, not the variable name of the logger.

...
app_logger = logging.getLogger("App")
configure_azure_monitor(connection_string="", logger_name="App")
...

Hi, sorry for the delay in replying, I was actually not sure what other actions I should perform if this is a valid request but could not be supported at the moment.

This issue would have to be implemented for this feature to be enabled.
