No, it's in Reporting, but no longer on the Dashboard.
I think it was causing too many "false" support tickets, so they decided to do away with it in V9. Unfortunately, V9 intorduced a memory leak in the httpproxy, so it would have been nice to leave swap on the Dashboard.
false reports? no it's due to the belief by sophos that linux systems digging into swap isn't abnormal behavior for a properly functioning system..which has been proven to be incorrect.
