Notes
Short pieces on application analytics for network infrastructure capacity — written for operators who prefer clarity over chart theatre.
Average utilisation hides the paths that actually fill
A calm fabric average can mask a single saturated uplink if your application analytics never see path-level capacity.
Capacity windows need clean events before they need bigger pipes
Headroom debates collapse when duplicate counters and missing properties pollute the utilisation stream.
Measure relief, not only saturation
Capacity metrics that ignore time-to-relieve leave planners flying blind after the first congestion alert.
Hong Kong peak hours and capacity cadence
Regional traffic peaks change which capacity windows matter — and how often packs should refresh.
