Systems that aggregate logs like Sentry will group all captured warnings under the same event which makes it difficult to assess common warnings

[ericvsmith]

Could you give an example of the problem?

[mnito]

Of course, here's an example script to reproduce:

import logging
import warnings

import sentry_sdk
from sentry_sdk.integrations.logging import LoggingIntegration

logging.captureWarnings(True)

sentry_logging = LoggingIntegration(
    level=logging.INFO,
    event_level=logging.WARNING
)

sentry_sdk.init(
    "<ingest URL>",
    traces_sample_rate=1.0,
    integrations=[
        LoggingIntegration(
            level=logging.INFO,
            event_level=logging.WARNING
        )
    ]
)

warnings.warn("A warning")
warnings.warn("Another warning")

I attached a file of what it looks like in the Sentry UI. Notice both warnings under the same issue. When logging warnings directly with the logging module, each message arrives as a separate issue. These warnings from the warnings module are both grouped together under the same issue since Sentry groups all logs with the same format string together.
