I have been working on Integration of vCOPS with other devices to explore the capability and the large scope of monitoring vCOPS can perform.
Here i would like to share some steps to monitor Cisco Switches using SNMP Adapter provided for the vCOPS.
Pre-requisites for this configuration
1. vCOPS
2. Download the SNMP Adapter from here.
3. IP Address,community and SNMP version details of the Switch to be monitored.
Now Login into vCOps Admin UI with a user with appropriate access rights.
Click on Update ---> Browse the location of the Adapter (vcops-SNMPAdapter-X-XXXXXXX.pak) that was downloaded.
Click on Update.
Accept the EULA and Proceed further.
Once the Installation completes. It shows Update is successfull.
Now Login into vCOPS Custom UI with appropriate access rights.
Click on Admin---->Support-----> Info
On the Adapters Info Tab Click on the small icon 
Once this is done the SNMP adapter should show up in the list
Now that the adapter is installed. We need to Add an adapter instance and credentials to start discovering the devices.
Select Environment---->Configuration----->Adapter Instances
Select Collector (vCOPS)
Select SNMP Adapter from the Adapter drop down menu.
Now Add the credential for the switches
Click OK.
Now Discover the resources. Goto Environment overview---->List-----> Auto Discover resources
Now enter the details like IP range and map the credentials to the Instance as shown below
Once these details are given. vCOPS starts discovering all the devices that are present in this range.
Wait for the discovery results to populate the results of the discovered resource.
Click on Import to just discover and not collect any data and collect to start collecting the data.
Click OK
Now all the devices will show up on your Custom dashboard widgets.
