Memory Available is the most important memory metric for performance and preventing OOM.

Currently Memory Utilization is provided, but this has another calculation which for example sets all buffers as memory used. This way for example warnings of Memory Usage above 80% are triggered, while the droplet still has 50% memory available: Linux will try to use all free memory for caches and buffers.

Providing the Memory Available metric (which should conform to Memory Available in for example the command) will enable to set alerts which are useful and reduce false positives in alerts.
