|
|
|
|
|

This is a simple python tool that uses sysstat (sar) to plot cpu and ram usage.

Best used with screen:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
$ screen -dmSL chart python sargraph.py
|
|
|
|
|
$ sleep 1
|
|
|
|
|
$ screen -S chart -X stuff "label1\n"
|
|
|
|
|
$ sleep 1
|
|
|
|
|
$ screen -S chart -X stuff "label2\n"
|
|
|
|
|
$ sleep 1
|
|
|
|
|
$ screen -S chart -X stuff "q\n"
|
|
|
|
|
$ sleep 3
|
|
|
|
|
```
|
