Proactive Issue Resolution
Working in break-fix mode doesn't cut it anymore.
You need to know where the problems are in your network so you can proactively fix them.
If you knew where every misconfiguration or dropped packet existed, and why the problem was occurring, you could spend a few minutes fixing the problems before users are affected.
This means you no longer run a network that's full of unknown mysteries – you oversee a network that is perfectly operating because you know what your equipment knows about problems.
