pmon

pmon is a computer performance system monitor tool which can capture process information for a period time and save it to a file. It's a tool based on nmon having all the functionalities of nmon and an additonal functionality with atop to capture specified process information and save it to a file which can be shown as charts in NMONVisualizer.

• nmon is a computer performance system monitor tool(see https://nmon.sourceforge.net/pmwiki.php)

• atop, which is an ASCII full-screen performance monitor for Linux that is capable of reporting the activity of all processes(see https://github.com/Atoptool/atop), is integrated in pmon to support capturing disk I/O and network information

Additional functionality

Multiple processes can be specified to capture their resources usages, including CPU, memory, disk I/O and network.

The root privilege is needed to capture the disk I/O information, for the network information, netatop service should be started before running pmon.

Please check https://www.atoptool.nl/downloadnetatop.php for netatop installation.

Option to specify the processes

The option to specify the processes is:

-i pid1,pname1[,pid2,pname2][,pid3,pname3]...

Multiple processes can be specified. The process name can be anything you want which is just used to show the metrics in NMONVisualizer. The metrics/resources usages will be shown as pname.cpu, pname.mem, pname.disk and pname.net.

Example to capture process information

The following is an example to capture the process information for both the processes with pid=26165 and pid=287:

./pmon -f -c 100 -s 1 -F ./example.nmon -i 26165,node1,287,node2
