NCP-GENL Production Monitoring and Reliability Practice Question
Which metric provides the best indication of 'inference queue saturation' in a Triton deployment?
⚠ Common exam trap
Candidates often choose GPU utilization or throughput. These metrics indicate how well the hardware is working, but they do not reveal if requests are being delayed in the server's input buffer.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Request queue duration
Queue duration is the most direct indicator of saturation. It measures how long an inference request spends waiting in the server's input buffer before it is processed by the GPU. In a production environment, monitoring this metric is crucial to identify when the server's request capacity has been exceeded, allowing for auto-scaling triggers to provision more instances and maintain performance standards during traffic spikes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Total GPU memory usage
Why it's wrong here
Memory usage tells you if the model fits, not whether the server is keeping up with requests. High memory usage is not directly correlated with queue saturation, as a server could have plenty of free VRAM but still have a massive request queue.
- ✓
Request queue duration
Why this is correct
Queue duration measures the time a request waits before being executed. An increasing trend in this metric is the definitive sign that the inference server is unable to process incoming requests as quickly as they arrive, indicating clear saturation.
- ✗
GPU temperature
Why it's wrong here
Temperature reflects the physical health and cooling efficiency of the GPU. While overheating can indirectly slow down processing, it is not a direct measure of request queuing or saturation, making it an unreliable indicator for this specific purpose.
- ✗
System clock speed
Why it's wrong here
Clock speed is a hardware-specific metric that fluctuates based on power management states and workload demands. It does not provide actionable insight into how many requests are being queued or the overall throughput capacity of the inference server.
