Perhaps for looking back to see the history of things, a unified ledger is convenient. But as a notifications/alerts solution it’s terrible because it essentially guarantees that the signal to noise ratio will be incredibly low.
This just depends on how disciplined you are. We use a system where backend errors are logged to slack, and then we treat addressing the source of the errors as an immediate priority. Keeping the SNR high is a priority. Plus generally being very selective about what goes into the channel.
