Sitecore - Filter out Sitecore Errors

We are hosting sitecore 8.1 in azure web apps. We log the errors on to App Dynamic where the application ticket will auto-created for each error.

The problem is that 90% of errors are raised by builtin sitecore piepelines e.g. GeoIP service not setup, session end not setup (due to MongoDB) etc.

Is it possible to identify and filter out the errors raised by built in pipelines and events in Sitecore?



I cannot see how this is related to Mattermost - can you please specify?
