I am in a discovery phase of trying to find out what is out there for Network Monitoring. Beside realtime and historical reportings I am also looking for something that can help in troubleshooting LAN/WAN related issues. For example: I have users reporting slowness at one of my remote sites and today I can see the traffic load on the WAN interface but I can't tell what type of traffic or who is taking up bandwidth.
Thanks in advance !!! I appreciate any inputs / suggestions !!
