Hello;

I need to know if I have to increase my RAM on the machine as I am running call center application on it and the results as following:

Is it working well?

It is normal for linux to use most of the RAM. If you had less memory, it would probably still run well, but would have to reload some data (or software) from disk a little more often.

I mostly pay attention to swap use. You are not using much – 300M out of 8G. And your system has been up for 42 days. That looks fine to me.

Unless your system is behaving sluggishly due to heavy swapping, I would not add memory.
