CPU usage 100%
Hi there!!!
My Linode CPU Utilization is 100%. I have only 2 websites currently integrated on this and have 160gb disk space out of that only 20% used and also ram with 8 GB out of this 81.4% is used why ram is taking more usage even though we have only two websites.
Load status?

Hi! I'd recommend first checking which processes are consuming the most CPU and memory resources on your Linode. You can monitor this in real time with top, or run the following commands from your terminal (or through Lish):
CPU
top -bn 1 -o %CPU | head -n 15
Memory
top -bn 1 -o %MEM | head -n 15
If one particular process is running away with most of the resources, you could try tuning it. For example, a few common applications that you might experience this with are Apache, MySQL or PHP. Here are some related guides on tuning these:
