Memory usage reported in pm2.io does not correspond to what is shown by `htop`

I suspect that the memory calculation displayed on PM2.io may be calculated or labeled incorrectly. In the images below, PM2.io shos that there is 25% memory free with 0.8 GB of memory used (I assume the discrepancy here is just a rounding error). However, when compared to the output of htop when on the machine, I only see ~25% memory utilization.

PM2.io pm2-server

htop htop

The number, at least, are in agreement but may be labeled incorrectly on the web portal? Thanks for such a great tool and service!

Now I'm a little more confused, as the number from top seem to be similarly disagreeable image

Perhaps, this is because this is a cloud server on shared hardware?

Does pm2-server-monit itself take up significant resources? Has anyone documented how much? Does it increase with the number of processes?
