Nslookup is a command testing and troubleshooting the DNS servers.
Nslookup can be run in two methods.They are interactive and noninteractive. Noninteractive mode is useful when only a single piece of data n eeds to be returned.
Syntax: nslookup [-option] [hostname] [server]
some times it may need to get the dns details for the large number of servers at that time we need to run the command multiple times and capture the values each and time we hit the command.
To simplify this situation i have found an interesting too named as dnsdataview tool.
You can nslookup multiple number of servers at a single click with the clean GUI.

Perceiver is the new monitoring tool.This is introduced because Companies invest in enterprise applications and infrastructure to deliver optimal service to their end-user community. IT organizations are asked to manage more systems with fewer resources, while reducing costs. Performance Analysts and Capacity Planners are often asked to create volumes of custom charts and graphs for different audiences, instead of focusing on high value capacity planning and performance engineering responsibilities that provide a greater return on investment for the company.For this it is the best solution to use the BMC perceiver tool.
