The cloud monitoring service CES cannot see the memory usage and disk usage of the elastic cloud server. This may be because the current operating system is Linux.

Question

Options

• ATrue
• BFalse

• A
  24% (7)
• B
  76% (22)

Explanation

Option B is correct because the inability of CES (Cloud Eye Service) to display memory and disk usage is not caused by the operating system being Linux - it applies equally to Windows instances. The real reason these metrics are missing is that the CES Agent (also called Telescope) has not been installed on the Elastic Cloud Server. Without the agent, CES can only collect hypervisor-level metrics like CPU usage and network throughput, since memory and disk usage require in-guest data collection.

Option A is wrong because it incorrectly treats Linux as the root cause, implying Windows would not have this limitation - which is false. Both Linux and Windows ECS instances need the CES Agent installed to report memory and disk metrics.

Memory tip: When CES is missing memory or disk data, think "agent not installed," not "wrong OS." The agent requirement applies to all operating systems equally.
