Observer offers both real-time monitoring and troubleshooting, as well as a complete trending and baselining collection system to  view historical data collected for days, weeks, months or even years.

Observer can be upgraded to Expert Observer or Observer Suite to track multiple SNMP-enabled devices, view data from any RMON1/2 or HCRMON probe, provide expert analysis and modeling, or display Web based reports. The Observer product line can provides a complete management solution for even the most complex LAN/802.11/WAN/Gigabit environments.
