Add swap visualizations to Nodes dashboard.
In cases where there are services that take a lot of memory or when there are bursts of memory consumption, a lot of this memory can be sent to swap.
If it's too much, and many/important services are using swap memory, they can become very slow.
In the current dashboard, the memory usage visualizations could drop after sending a lot of this memory to swap. But the services might actually be using a lot of swap and become slow.
I'm attaching an image of how it looks like.
