How to get all dimension values in MetricDataResults in CloudWatch

I have a search expression that looks like this:

stats = cloudwatch.get_metric_data(

        MetricDataQueries=[
            {
            "Id":'m1',
            'Expression': "SEARCH('{ABC/HEARTBEAT,Client_Email, Clinic_Id, NodeName} MetricName=\"PING_PONG\" Clinic_Id = 7667', 'Average', 864000)",
            'ReturnData': True,
        },

        ],
        StartTime=Util.utcnow() - timedelta(hours=2),
        EndTime=Util.utcnow(),
    )

It returns:

{
    "Messages": [],
    "ResponseMetadata": {
        "RetryAttempts": 0,
        "HTTPStatusCode": 200,
        "RequestId": "2f33cc09-61ff-40b0-9d28-72c4d949b2f0",
        "HTTPHeaders": {
            "x-amzn-requestid": "2f33cc09-61ff-40b0-9d28-72c4d949b2f0",
            "date": "Fri, 06 Dec 2019 22:47:25 GMT",
            "content-length": "928",
            "content-type": "text/xml"
        }
    },
    "MetricDataResults": [
        {
            "Timestamps": [
                "2019-12-06 20:47:00+00:00"
            ],
            "StatusCode": "Complete",
            "Values": [
                1
            ],
            "Id": "m1",
            "Label": "[email protected]"
        },
        {
            "Timestamps": [
                "2019-12-06 20:47:00+00:00"
            ],
            "StatusCode": "Complete",
            "Values": [
                1
            ],
            "Id": "m1",
            "Label": "[email protected]"
        }
    ]
}

I need to get value of Client_Email, NodeName for the metrics that have Clinic_Id = 7667

Currently, I get Client_Email as Label (Not sure why) but I need both Client_Email and NodeName

Update:

u'MetricDataResults looks like this for me:

u'MetricDataResults': [{u'Timestamps': [], u'StatusCode': 'Complete', u'Values': [], u'Id': 'm1', u'Label': 'abc'}, {u'Timestamps': [], u'StatusCode': 'Complete', u'Values': [], u'Id': 'm1', u'Label': 'abc2'}]

Why do I have empty array in Timestamps and Values?

Label is the only place in the response where this value could be. I suspect you only have 1 distinct value for NodeName and that is why the label contains only the Client_Email. If you had more combinations of emails and node, they would show in the label, separated by space.

If you're not interested in the values of the metrics, but only in the values of dimensions, you could use list-metrics API, like this for example:

response = cloudwatch.list_metrics(
    Namespace='ABC/HEARTBEAT',
    MetricName='PING_PONG',
    Dimensions=[
        {
            'Name': 'Clinic_Id',
            'Value': '7667'
        },
    ],
)
