Threshold of 4GB is arbitrary and depends on the process being monitored. Adjust per group.

comments: |
Threshold of 80% is per-core. Adjust based on expected workload.

Threshold of 10000 switches/s is a rough default. Adjust based on the workload profile.

Detects restarts by watching for changes in the oldest process start time within the group.
