A user is publishing custom metrics to CloudWatch. Which of the below mentioned statements will help the
user understand the functionality better?
A.
The user can use the CloudWatch Import tool
B.
The user should be able to see the data in the console after around 15 minutes
C.
If the user is uploading the custom data, the user must supply the namespace, timezone, and metric
name as part of the command
D.
The user can view as well as upload data using the console, CLI and APIs
Explanation:
AWS CloudWatch supports the custom metrics. The user can always capture the custom data and upload the
data to CloudWatch using CLI or APIs. The user has to always include the namespace as a part of the request.
However, the other parameters are optional. If the user has uploaded data using CLI, he can view it as a graph
inside the console. The data will take around 2 minutes to upload but can be viewed only after around 15
minutes.
B I like
C – Publish Custom Metrics
http://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html
You can publish your own metrics to CloudWatch with the put-metric-data command (or its Query API equivalent PutMetricData). For more information, see put-metric-data in the AWS Command Line Interface Reference. You can view statistical graphs of your published metrics with the AWS Management Console.
Ans B:
http://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html
When you create a new metric using the put-metric-data command, it can take up to two minutes before you can retrieve statistics on the new metric using the get-metric-statistics command. However, it can take up to fifteen minutes before the new metric appears in the list of metrics retrieved using the list-metrics command.
B is right
Description
Add metric data points to a metric. This call will put time-series data, for either the raw value or valid statistic values of a given metric name. It supports the input of a single data point at a time.
Note
When you create a new metric using the mon-put-data command, it can take up to two minutes before you can retrieve statistics on the new metric using the mon-get-stats command. However, it can take up to fifteen minutes before the new metric appears in the list of metrics retrieved using the mon-list-metrics command.
B
b
I will go with B.
Even though option C makes sense, it is good that user must know the data uploads in 2min and he/she can see only after 15mins.
b
D is incorrect, console is not an option, CLI and API are valid.
C is incorrect, namespace is the only mandatory variable
A is incorrect, only CLI and API are valid
B is the correct answer
D
With my own tests I noticed the “–metric-name” and ” –value” are also mandatory, in spite of what the man pages tells me.
The timezone is not a valid parameter, so B is the correct answer, but the Explanation is not correct.
