Memory useage
Posted: Thu Apr 13, 2017 3:20 am
Hi all, I'm wondering if someone can help me understand my server's memory usage.
I have a 4 GB DigitalOcean droplet running 6 WordPress websites. 20,000 total monthly pageviews.
My DigitalOcean graph shows me approaching 80% memory usage:

But free -m shows this:
This doesn't match the 80% suggested by the DigitalOcean graph.
To add to the confusion, when I run htop sorted by memory I see 21 mysql processes each using 7% memory (which comes to 161% memory).

I am not sure what to make of this. Thanks in advance for any help.
