✑ 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?
✑ 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?
