Enabling Metrics for the AWS SDK for Java failed without no error msg about aws-sdk-java HOT 4 CLOSED

-Dcom.amazonaws.sdk.enableDefaultMetrics=cloudwatchRegion=us-east-1

If there's no error in the logs and no metrics are being published to Cloudwatch, my guess is that the system property is not being picked up by your application for some reason, or the application doesn't live long enough to send Cloudwatch metrics (metrics are pooled and sent every 2 minutes or so).

I tested the system property in my local machine and it is working normally, I tested us-east-1 and ap-northeast-1 regions.

If you still want to investigate this, you can try to increase the log level to see if more detailed errors show up when the metrics publisher try to send the requests to Cloudwatch.

Hi, I have a test with this sdk and here is what I found.

As a workaround, I tried to enable this feature by adding
AwsSdkMetrics.enableDefaultMetrics();
before sending s3 requests and finally java sdk can send metrics to aws cloudwatch successfully.

However, adding system properties -Dcom.amazonaws.sdk.enableDefaultMetrics=cloudwatchRegion=us-east-1 to jvm is not an effective method since now.
If it is, this may be a sdk issue.

Just for your reference.

Hi, debora.
Thanks for your reply.

I have a test in my local machine and still meet the issue.
Before you reply, I have run the application for a long time(0.5h) and enbled the debug level with the log4j tool.
Below is the config of log in my applicatiopn.

log4j.rootLogger=DEBUG, A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c -  %m%n
# Turn on DEBUG logging in com.amazonaws.request to log
# a summary of requests/responses with {AWS} request IDs
log4j.logger.com.amazonaws.request=DEBUG

Can you provide the version of java and the java sdk, and do you pass the system property same as my method as below.
java -cp test.jar org.example.S3ClientDemo -Dcom.amazonaws.sdk.enableDefaultMetrics=cloudwatchRegion=cn-north-1

Thanks for your help.

I believe system properties should go first:

java -Dcom.amazonaws.sdk.enableDefaultMetrics=cloudwatchRegion=cn-north-1 -cp test.jar org.example.S3ClientDemo
