Or, I used to work for a major bank and part of my job involved making sure if we had a problem like a server crashing ops could see it was a server for service X and it was 1 of 8 backup servers. Our servers just in Europe were in the 10s of thousands so we needed that kind of triage.
So we had this tool that showed services something like a spiderweb (technically a directed acyclic graph) with the service (say internet banking) as the hub and all the servers, databases etc at the ends. If we had a problem you'd see a yellow or red line from the node towards the hub. Alerts would reinforce each other, so if two DB servers in the same cluster had a problem it would be marked as more serious. Very sensitive to make sure we caught every problem. Most people would see the subtree of a given service but we also has a total overview for heads of ops etc. It was a tool for ops and service support teams to give context to alerts.
Our senior manager didn't tell us he'd launched his own project to include this in a new management dashboard for the regional CIOs, COOs and boardroom for which he'd take all the credit. The first we heard was when the owner of a very visible service for very very rich people was pissing his pants because his service was "down". All the people looking at this saw was that it was "down" not that 2 backup servers, 1 out of 4 sql servers in a cluster and a couple of other things had the kind of BAU issues you expect of busy servers. RAM at 80% use, disk space below low warning threshhold. Most of these wouldn't even go to ops, just automatically generate a ticket to go the appropriate team.
I had a chat with ops management and built a "context sensitive view for management oversight" (IIRC). I calculated once that if you nuked 3 out of 4 of our biggest datacenters you might just get a "service affected" warning. In the meantime, my team, ops, service management, the support teams in the various services and so on spent many thousands of man hours trying to explain to panicked business managers that their services were just fine.
