License block: Vezha capabilitiesWhat showsRAM free, % in Vezha corresponds to the mem.free_pct metric.It normalizes the available memory as a percentage and allows you to compare nodes with different amounts of RAM.Why is this important?For a fleet with mixed configurations, a percentage is often more informative than an absolute number.This makes it easier to set unified alerting policies and see risks even before critical conditions.An example from practiceThe two servers had different amounts of RAM, but the same percentage of free memory dropped sharply after the release.This quickly showed the systemic nature of the problem, rather than a local failure of a single node.
