Clueless at the prompt

Linux! I don't know how it works anymore.

Lately, I have been putting a few hundred RHEL boxes into production and am finding it very difficult to do very simple things.

How do I make sense of the top output? How do I find out how many packets are being dropped because there is no listening socket? Which partition is mapped to which volume? How do I use “ip addr” commands? How do I detect disk/mem failures?

I bet I will have to relearn most things in another years time. Why cant things just stay the same???
