Besides running top, is there a way to see what RAM is allocated to my linode?
Generally, Linode plans are named after RAM allocated to them. For example, a 1GB/1024 plan has 1GB of RAM, while a 4GB/4096 plan has 4GB of RAM.
Otherwise, you can always check your RAM usage by logging into your Linode and running the command free -m which will output statistics in MB.
free -m
