Kafka - Monitoring and Operations

You want to calculate the broker's network throughput efficiency. You have these metrics:
BytesInPerSec = 3,000,000
BytesOutPerSec = 2,500,000
RequestHandlerAvgIdlePercent = 20
Which formula best estimates throughput efficiency?

ABytesOutPerSec + BytesInPerSec + RequestHandlerAvgIdlePercent

B(BytesOutPerSec / BytesInPerSec) * (100 - RequestHandlerAvgIdlePercent) / 100

C(BytesInPerSec / BytesOutPerSec) * RequestHandlerAvgIdlePercent / 100

DRequestHandlerAvgIdlePercent / (BytesInPerSec - BytesOutPerSec)

Step-by-Step Solution

Solution:

Step 1: Understand throughput efficiency components
Efficiency depends on output/input ratio and active request handler time (100% - idle percent).
Step 2: Apply formula combining these metrics
(BytesOutPerSec / BytesInPerSec) * (100 - RequestHandlerAvgIdlePercent) / 100 correctly multiplies output/input ratio by active handler fraction.
Final Answer:
(BytesOutPerSec / BytesInPerSec) * (100 - RequestHandlerAvgIdlePercent) / 100 -> Option B
Quick Check:
Efficiency = Output/Input * Active handler time fraction [OK]

Quick Trick: Combine output/input ratio with active handler time for efficiency [OK]

Common Mistakes:

MISTAKES

Adding metrics instead of multiplying ratios
Using idle percent directly without subtracting from 100
