  Top Talkers
bulletUnderstand bandwidth usage by device
bulletDetermine if a station is consuming too much bandwidth
bulletView LAN use patterns
bulletDetect faulty network hardware
bulletMake informed decisions about network segmentation
bulletFind broadcast storms
bulletReview switch usage and resource allocation

Top Talkers is the first screen I check every morning. It's a good snapshot to help me see if the network is healthy or if something is out of the ordinary. I can watch protocols, see what traffic is work-related - sometimes its an easy problem like a bad NIC sending out too much chatter. With Observer I can see all this activity and proactively manage my bandwidth levels.
