問題文
The monitoring pages show processor utilization for a new instance but no memory utilization at all. The instance is running and healthy. What explains the gap?
選択肢
- The metric namespace for the instance is set to the infrastructure namespace and the instance needs a second interface that carries the values when it publishes them.
- The retention period for the metric has already passed and the console keeps a value for a shorter window than it keeps a log.
- The alarm for memory utilization has not been created yet and the console shows a metric once an alarm names it inside a query of its own.
- The plugin that gathers metrics from inside the guest is disabled and the instance also needs a service gateway or a public address before it can publish those values.
