Can't append procstat to config

[damiendurant]

Hi,

I use ssm to configure cloudwatch using AmazonCloudWatch-ManageAgent.

First with configure action, and the following configuration from parameter store :

{
	"agent": {
		"logfile": "c:\\ProgramData\\Amazon\\AmazonCloudWatchAgent\\Logs\\amazon-cloudwatch-agent.log"
	},
	"metrics": {
	    "append_dimensions": {
			"InstanceId": "${aws:InstanceId}"
		},
		"metrics_collected": {
			"Memory": {
				"metrics_collection_interval": 5,
				"measurement": [
					"% Committed Bytes In Use"
				]
			},
			"procstat": [{
				"exe": "KAVFS",
				"measurement": [
					"pid_count"
				]
			}],
			"LogicalDisk": {
				"measurement": [{
					"name": "% Free Space",
					"unit": "Percent"
				}],
				"resources": [
					"*"
				]
			}
		}
	}
}

Then, I use the append action to add some metrics :

{
"metrics": {
    "metrics_collected": {
			"procstat": [
                                {
				"exe": "W3SVC",
				"measurement": [
					"pid_count"
				]
				},
            	{
				"exe": "IISADMIN",
				"measurement": [
					"pid_count"
				]
			}]
}
}
}

Therefore the agent crash trying to merging the configuration

2020/12/01 14:40:53 Under path : /metrics/metrics_collected/procstat | Error : Different values are specified for procstat

How to handle this ?
