One day, after overhearing endless complaints about outages and network slowdowns, a seasoned ex-IT manager stepped into my cube to make a suggestion. "Measure the actual network speed all day, graph it and tape it to the wall outside your door," she said. "Do the same for system availability, and you and the users will know where you stand." I quickly went about implementing this and it worked. First, I found out that I had a network bottleneck because I had based my LAN design on the shape of the building rather than on the number and type of workers in those areas. But the important finding came next. By proactively recording and sharing performance and availability metrics, my users became much happier with the state of our systems. They now understood that a single outage was an anomaly rather than the rule. So let's talk about how you can use metrics to improve service and satisfaction. We'll start with a discussion of base metrics and ... Access >>>
