Our development department has developed the monitoring program 'N2' with which you can easily monitor the resource consumption of your VPS. This program also makes it easy to investigate the causes of problems that have occurred. It is also possible to configure it to send e-mail notifications when certain problems occur.
We have made this system available as open source software so it can be used by everyone.
N2 works for Windows and Linux.
