We are using TOP to monitor load on LInux production server.
I just wanted to know if TOP is a resource intensive command?
Whether TOP adds up to the load on server. Say for example TOP running simultenously from 5/6 putty sessions.
Running top with default parameters is not a resource intensive process. There were issues with long running top sessions in the past, with ported versions of the top command on certain Unix platforms, but Linux was not affected. I don't think you will notice a performance issue running several top sessions. You can easily test it. Whether or not the top utility is the right tool for what you are trying to accomplish however is a different question.
