         -o O        Output file name for collecting data (default: None)
         -i I        Time Interval(in seconds) to take samples (default: None)

system_monitor draw_chart -h

         usage: system monitoring draw_chart [-h] [--files-to-compare file_names]
                                [--process_name process_name]
                                [--field-name field_name]
                                [--chart-type chart_type] [-o O] [-i I]

         optional arguments:
         -h, --help            show this help message and exit
         --chart-type chart_type
                    Type of chart to plot Chart type can be line or column
                    (default: line)

         required named arguments:
         --files-to-compare file_names
                    Excel files to compare (default: None)
         --process_name process_name
                    Process name to draw chart (default: None)
         --field-name field_name
                    Field name to compare. Field name can be memory, cpu,
                    loadavg1x, loadavg5x, loadavg15x (default: None)
         -o O       Output file name for drawing chart (default: None)
         -i I       Time Interval(in seconds) to take samples (default:
                    None)

Example:

         system_monitor system_monitor -p "systemd glusterfsd glusterd" -o "/tmp/node_1.xlsx" -i 5
         system_monitor draw_chart --files-to-compare "/tmp/node_1.xlsx /tmp/node_2.xlsx" --process_name "glusterd" --field-name "loadavg1x" -o "/tmp/chart.xlsx" -i 5

Note:

With system_monitor option, the data will get collected in excel sheet unitl user terminates the script. If you try to monitor different process in the subsequent runs, then collect the data in new output file.

Future Enhancements:

• Adding error handling if process names are not found in system.
• Feedbacks are welcome.
