Description
When initializing a metrics context, but not emitting metrics, aws-embedded-metrics still generates output.
Here is a minimal example:
#!/usr/bin/env python3
import os
os.environ["AWS_LAMBDA_FUNCTION_NAME"] = "dummy-function-name"
from aws_embedded_metrics import metric_scope
@metric_scope
def foo(metrics):
pass
foo()I'd expect no output from this script, however this is what I get (pretty-printed for better readabillity):
{
"LogGroup": "dummy-function-name",
"ServiceName": "dummy-function-name",
"ServiceType": "AWS::Lambda::Function",
"executionEnvironment": "",
"memorySize": "",
"functionVersion": "",
"logStreamId": "",
"_aws": {
"Timestamp": 1598537498307,
"CloudWatchMetrics": [
{
"Dimensions": [
[
"LogGroup",
"ServiceName",
"ServiceType"
]
],
"Metrics": [],
"Namespace": "aws-embedded-metrics"
}
]
}
}I believe this behavior is unintended and I see not much benefit in such output without actual metrics.
