I have installed an Ubuntu server 16.04
in a VM from vultr (my plan is 2 CPU, 4GB RAM) and I noticed today in the admin panel that the CPU usage the last month is over 100% (currently is in 103%).
In the server a web server is deployed (Apache
) and some small WordPress
sites are hosted.
How is possible to use over 100% than you have? Is this a sign that I should upgrade to a higher plan with more resources?

If you should be worried or not depends on what the data represents. If it's per cpu then you have a "100%" for every cpu. Say, if the server it's a quad processor you could have a total load of 400%.
That said, it's possible to have an overload or spikes because the processes are putted on queue. Here you ave a simple but good reading

Before upgrading i would check top and optimize apache and php processes.
