Topic: Professional Cloud Architect topic 1 question 190
You have a Compute Engine application that you want to autoscale when total memory usage exceeds 80%. You have installed the Cloud Monitoring agent and configured the autoscaling policy as follows:
✑ Metric identifier: agent.googleapis.com/memory/percent_used
✑ Filter: metric.label.state = 'used'
✑ Target utilization level: 80
✑ Target type: GAUGE
You observe that the application does not scale under high load. You want to resolve this. What should you do?
A.
Change the Target type to DELTA_PER_MINUTE.
B.
Change the Metric identifier to agent.googleapis.com/memory/bytes_used.
C.
Change the filter to metric.label.state = 'used' AND metric.label.state = 'buffered' AND metric.label.state = 'cached' AND metric.label.state = 'slab'.
D.
Change the filter to metric.label.state = 'free' and the Target utilization to 20.
