Veeam Monitor 1.0 is very similar to VC performance graphs but it is improved in several ways:
First of all it uses performance data that VMware provides but stores it more efficiently into SQL database.
The data is condensed and optimized for the historical reporting.
Second, Veeam Monitor provides for single-screen detailed monitoring of key usage and performance statistics, such as CPU, memory, disk, network, and swap usage for cluster, resource pool or virtual machine
Because of the better UI, you can easily switch between metrics and select multiple counters.
Another thing is the TOPs section where you can immediately see the top 3 consumers (VMs) for CPU, Memory, Disk, Network and Swap.
