Just a query for neatness sake really! We have a Tableau 8 setup with 2 gateway servers (active/warm-standby) and 2 worker servers. As part of infrastructure testing I noticed that if you stop the Tableau service on one of the worker servers then, if users happened to be connected to that one, for 5 minutes you'll get "HTTP 500" errors whilst the application sorts itself out in the background.
To make things as smooth as possible for end users I want to put up a custom HTTP 500 error page saying something along the lines of "service is currently impacted please wait 10 minutes and try again. If the problem persists contact support...".
I assumed that as the implementation uses Apache in the background a quick tweak to httpd.conf to point to a custom page would do the trick but it doesn't seem to be the case. Has any got any suggestions on if this is possible and how to do it?
