PAS-C01 Technology Practice Question
A company is running an SAP NetWeaver system on AWS. The system includes a primary application server (PAS) and a dialog instance. The administrator wants to monitor the SAP system health using Amazon CloudWatch. Which THREE metrics should be monitored to proactively detect performance issues? (Choose THREE.)
⚠ Common exam trap
The trap here is that candidates often focus on CPU and memory metrics (like SwapUsage) because they are common in general server monitoring, but for SAP on AWS, storage I/O performance (EBS Queue Length) and SAP-specific work process utilization are more directly tied to application responsiveness and must be included alongside CPU Utilization.
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
✓
EBS Volume Queue Length
EBS Volume Queue Length is a critical metric for SAP workloads because it directly indicates I/O latency. A high queue length means the storage subsystem cannot keep up with the SAP database or application server I/O requests, which can cause transaction delays and system hangs. Monitoring this metric allows proactive detection of storage bottlenecks before they impact SAP performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
EBS Volume Queue Length
Why this is correct
High queue length indicates I/O requests waiting, often a sign of storage bottleneck.
- ✗
EC2 SwapUsage (as custom metric)
Why it's wrong here
Swap usage is important but not a standard CloudWatch metric; it requires custom monitoring.
- ✓
EC2 CPU Utilization
Why this is correct
High CPU utilization can indicate performance issues.
- ✗
EC2 NetworkIn
Why it's wrong here
NetworkIn is usually not a direct indicator of SAP health unless there is a network bottleneck.
- ✓
SAP work process usage (via SAP monitoring)
Why this is correct
If work processes are fully utilized, the system cannot handle more requests.
