Hey, @Balamurugesh ,
Short answer: yes, it does!
Basically, you can setup a Slack integration based on any Alerting Profile:
And you can setup an Alerting Profile containing only problems related to Errors on Application:
As there isn't (at least, not that I know of) any way to filter Impact Level on an Alerting Problem (to only alert on problems on the Application impact level), they way to do it (as pointed out by my second arrow) is through tags.
You need to tag all Applications (at least, all the ones you want to be alerted on Slack) with that tag.
An advantage of this approach is that you can tag Web Applications, Mobile Applications, Custom Applications and even Synthetics with it, and they will be accounted for on this Alerting Profile and, as such, be present on Slack alerts.
Hope this helps!
