dev.queue-depth Calculator
Calculates message queue depth growth rate, consumer lag, and time to drain at various consumer scaling levels. Queue depth growing faster than consumers can drain indicates under-provisioning — the queue acts as a buffer until consumers scale out.
Inputs
Arrival
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Service
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Workers
Energy transferred by a force over a displacement (J = N·m).
Timeout
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
utilization
Fraction of capacity actually being used. Above 80–85% is typically considered high utilisation; above 95% leads to queuing and latency spikes.
avg queue depth
The computed depth.
avg wait (ms)
Reference formula or conversion factor shown for context.
avg in system
Sample size or count used in the calculation.
stable?
Reference formula or conversion factor shown for context.
