The indicator system performance - indicator-multiload showing graphs of CPU, memory and swap, and network traffic.
Sorry for the spelling and phonetic errors in the text.

By default indicator-multiload displays only one graphic processor.
Settings allow you to fully customize the indicator: what parts of your equipment monitored, how often, and what graphics displayed in the panel. You can also customize the colors used for the graphs on the panel.
Installation into Linux Mint:
sudo apt install indicator-multiload
If you want to install the most recent version of the indicator, connect the official repository. But in my (Linux Mint 17 Mate) the latest version is not stable worked.
sudo add-apt-repository ppa:indicator-multiload/stable-daily sudo apt update sudo apt-get install indicator-multiload
