Our small company is sometimes experiencing real slow down issues on our Internet connection. The problem is we don't have any idea where it comes from.
I wanted to be able to monitor computers' network usage to spot where the issue comes from, but I haven't found a good software to do so. I can use
Wireshark but I would like to view the data in a graphical way.
Other software I tried are only trials or limited versions, so it's not really long term solutions.
Almost all our computers are using Windows (XP, Vista, 8 or 10) and we have two Allied Telesis switches AT-GS950/48.
I'm looking for a solution that does not imply to install an agent on every computer.
I don't know which kind of data it is best to monitor. Since I want to know if the switches are overloaded, I would say Bytes/sec. I don't know if the switch have a monitor port, but it is possible to configure them with SNMP.
