Appropriate Network monitoring software - Network Performace Monitor

Hi there,

Thanks for reply,

As networking support company, sometime new customers call us to find out issue related to their Local area network such as slow access during the day to the servers and internet, part of the network connected to a particular switch is working fine but computer connected to other switch in the building are getting slow access to share files from the server etc. We manually (by turning off part of network) find issues such as bottlenecks or network broadcast etc.

So looking for a solution which can help us provide network health.

Hope this information will help to suggest a product

best regards
