Your question is too vague to answer. What do you mean by "complete user activity"? Any windows opened? Just logins/logouts? Shell history only? What?? And did you try putting "linux user activity monitoring" into Google first???
And, as has been said to you several times now, have you contacted Red Hat support???
They can answer questions like this, and perhaps even have solutions they can point you to. Since you're using RHEL, you should be PAYING for it...since you are, you're also paying for support/assistance, and access to their knowledegbase.
