Introduction to WanSpy
Today?s computer networks doesn?t just confined to LAN, it is distributed over wide area across building, cities and countries through WAN Link. WAN link is still expensive and may be point of bottleneck many a times. It can be very difficult to keep computer networks up and running without monitoring and analysis of WAN utilization.
Monitoring and Analyzing WAN utilization may be important if Internet is the case.
How well this very useful resource of Organization is utilizing, may be a point of consideration in any organization.In these scenarios Network Administrator may look for a tool with which he can monitor WAN link and Internet Usage.
Overview of WanSpy
WanSpy is intended to give Network Administrator a visual view of how his
Expensive Wan Bandwidth is getting utilized. In addition to online monitoring WANlink, WanSpy also facilitates Network Administrator to keep record of WAN usages for inventory purposes.
WanSpy is based on SNMP (Simple Network Management Protocol) accepted acrossindustry for management of computer networks.
Key feature of WanSpy is to showdata transferred by each host IP pair in terms of bytes and packets through Wan Link.WanSpy uses Cisco Router?s IP accounting for this purpose.
WanSpy also have various utilities graphs to show Network Administrator IP traffic,Interface traffic, Memory, CPU utilization and WAN Bandwidth utilization of Cisco Router.
Application of Wanspy
WanSpy can be use for two different applications.
•Monitoring, how WAN is currently utilizing.
•Generating Reports of Wan usages in certain time period for inventorypurpose.
