Memtierd Demo

Showcases how Memtierd can be used as a memory manager in Kubernetes to save memory by swapping out idle processes to swap.

This demo showcases how “high-prio” and “low-prio” workloads behave when they are managed by Memtierd. Low-prio workloads are swapped out more aggressively than high-prio workloads.

To replicate the demo you need more than just the dashboard. The required steps can be found here.

About the metrics

RAM Saved (G)

  • Tells how much RAM is being saved by swapping out the idle workloads.

RAM Saved (%)

  • Tells how big the total memory saved is in comparsin to the overall memory of the system.

Compressed (%)

  • Tells how well the data is being compressed.

RAM vs Swap

  • Tells how the memory is being distributed between RAM and Swap.

Page faults

  • Tells how many new page faults happen in between the requests from Grafana. This is a way to express the possible performance hit workloads experience if being tracked by Memtierd.
