We are bringing our IT support back to in house from a local british IT service provider.

We need the best network monitoring tool we put our hands on. I have selected Solarwinds Orion and OpManager. Can you please do a comparison between the products or please suggest any other better product.

We have more than 100 sites span accross UK and connected them via BT MPLS cloud.
Please let us know if there is any tool to monitor changes in the agreed bandwidth.

The reason why i ASKED THIS QUESTION IS BECAUSE WE HAVE INTERMITTEND PERFORMANCE ISSUES IN SOME OF OUR SITES.

I COULDN'T FIND ANY ISSUES IN THE LAN.

With the number of sites (assuming multiple devices per site), do make sure you select a tool up to that task ... many "simple to use" tools will quickly hit the brick wall trying to monitor large number of devices due to sequential checks and data access.
Personally, I'd go with OpenNMS - open source, designed for enterprise use (many devices, flexible). You can get commercial support from either OpenNMS Group itself or possibly certified (or at least experienced) service providers, which are able to help you with role-out, configuration, modification to your needs etc.
By its design, it can easily be scaled for large deployments, while keeping a decent central management (in contrast to some other "scalable" solutions which are more like "multiple instances with central display" - not very manageable ...)

First of all, to setup a network monitoring system in an enviroment as yours is not to be taken lightly, and it requires extensive training and testing before putting it live. It could take many months to setup, and I believe that you can troubleshoot your problem with much simpler and easier ways than just installing a new network monitor system.

When that is said, one of the best is CA's eHealth. I have been using that for 2 different ISP's, but it is also very compliacted to setup and you need to go to courses to learn about it, this is just one system that you cannot learn yourself.

Edit: I almost forgot the other tool I was using, Spectrum, a great multi-WAN realtime monitoring system: http://www.ca.com/us/root-cause-analysis.aspx

For network devices monitoring, I would recommend "spiceworks".

To monitor internet connections and bandwidth, "WFilter" is your choice.
