Thanks for response.
For ssh and DBI we will have two separate programs, and will be easy to maintain. for running in sequential, we will have problem.
Example: there is poosility of delay in process for few servers and might create problem when report won't be available on time.
I am thinking to use Thread::queue, will divide servers into 10-15 groups and kick off programm with GRP
as input parameter.
1. collector. pl GRP1 ## GRP1 will contain 30-40 dataserver
