An application that you are managing has EC2 instances & Dynamo OB tables deployed to
several AWS Regions In order to monitor the performance of the application globally, you would
like to see two graphs 1) Avg CPU Utilization across all EC2 instances and 2) Number of Throttled
Requests for all DynamoDB tables.
How can you accomplish this?
A.
Tag your resources with the application name, and select the tag name as the dimension in the
Cloudwatch Management console to view the respective graphs
B.
Use the Cloud Watch CLI tools to pull the respective metrics from each regional endpoint
Aggregate the data offline & store it for graphing in CloudWatch.
C.
Add SNMP traps to each instance and DynamoDB table Leverage a central monitoring server
to capture data from each instance and table Put the aggregate data into Cloud Watch for
graphing.
D.
Add a CloudWatch agent to each instance and attach one to each DynamoDB table. When
configuring the agent set the appropriate application name & view the graphs in CloudWatch.
B
b
Why not C?
b
the Answer is B
A- Wrong because the CW is only per reigon
C- wrong because the CW doesn’t support SNMP
D- wrong becaus there is no agent for the DynamoDB
Answer C is more appropriate after trying to verify from multiple sources , although there is no verifiable source or explanation from Amazon .
Also Video Courses from Acloudguru suggests the use of a Central Monitoring Server.
Correct answer is C .
I have verified this from multiple sources .
Also this follows the lead where you have monitoring agents are installed on all servers ( similar to SNMP traps ) and they send the information to the central monitoring server
