My team discontinued use of TBSM and moved to its replacement DASH, in early 2017. Although we still rely on it as our fail-over/back-up Event Presentation console, we have moved to another vendor product that provide Event Analysis and Incident Isolation via automation.
Product version discussed: 6.x
The most valuable feature for my team is the ability to taken event feeds from all/any source tool and put them in a single pane of glass. It's being replaced for our work by another Tivoli tool.
