What these steps have in common is that monitoring tools are not in sync with new changes in code or topology and this observability data is often siloed within different tools and teams. Observability is the ability to measure a system’s current state based on the data it generates, such as logs, metrics, and traces.

In a steady-state process (not allocating excessively) on a system with sufficient memory (this system had 64 GiB of RAM and roughly 47 GiB of that was available) the number of page faults should be close to zero, and this was a long way from that. I then looked in the “Virtual Memory Snapshots” table at the Working Set column.

How much time and effort does that save?
