CloudWatch2: InvalidParameterValueException

I tried using micrometer-registry-cloudwatch2:1.3.0 registry to publish metrics to CloudWatch. The metrics are generated by Spring Boot, and the repository is configured with a filter for “http.server.requests” metric.

I am getting this exception:

software.amazon.awssdk.services.cloudwatch.model.InvalidParameterValueException: The parameter MetricData.member.4.Unit must be a value in the set [ Seconds, Microseconds, Milliseconds, Bytes, Kilobytes, Megabytes, Gigabytes, Terabytes, Bits, Kilobits, Megabits, Gigabits, Terabits, Percent, Count, Bytes/Second, Kilobytes/Second, Megabytes/Second, Gigabytes/Second, Terabytes/Second, Bits/Second, Kilobits/Second, Megabits/Second, Gigabits/Second, Terabits/Second, Count/Second, None ]

Okay - while I do indeed have a memory leak that was introduced at the same time I moved to the cloudwatch2 library, it turns out to be a bug in my own application code (doing something badly with SQS queues). The coincidence in timing is that I moved to cloudwatch2 because I’m moving to the AWS SDK for Java v2.

So it all looks good to me.

I can indeed see metrics being published to Cloudwatch correctly now.

I’ve noticed that the earlier version also had a memory leak - my dev server was falling over after a few hours of idle use with the broken Cloudwatch logger. I’m now running a test to see if that continues with the SNAPSHOT, and will let you know of the results. (Again, all I have is the JvmMetrics being logged)
