NMS Primer 6: Ongoing Feeding

We’ve covered what an NMS does, selecting an NMS, and some tips on implementing an NMS. But how do we keep an NMS up-to-date and relevant? Signs of a well-maintained NMS: Most Operations Engineers have the console up at their desktop. It’s just part of the routine to look at it each morning. When people […]
