Hello, I have an Aritfactory setup which works, but not the best, probably the server resources are too low. What would be the best tool to monitor CPU/RAM/IO, etc. that also generates a nice graph or something in PNG format, readable by non-technical people?

The server is CentOS 7.

Based on this I can request resource increase, but at the moment without serious evidence, it's a bit harder.

Any info would be helpful, thank you!

KSAR is my default for people who want to visualize that which they fail to conceptualize.
BTW "serious evidence" would be the SAR output itself, this thing just makes cartoons . ( That said, one cannot underestimate the "Oooh Shiney!!!" factor of a well rendered cartoon on the soft minded).


If you really want to have fun and establish yourself as a "serious" 'puter scientist/engineer (sans the choo choo, of course) you probably want MATLAB, which is basically a 256 million color etch-o-sketch, but you have to be able to write in C/C++ to twist the knobs (It has a python API but if you use it, all the other 'puter scientists will say mean things about you, they are a snooty bunch...)
