Hi Manula,

Here is the autoscale-policy I am using for cartridge subscription

Syntax used for subscription is :   “subscribe-cartridge <type> <alias> -ap 
<autoscale-policy-name> -dp <deployment-policy name> “

{
        "id": "economyPolicy",
        "loadThresholds":
        {
            "requestsInFlight":
            {
                "average": "300",
                "gradient": "0",
                "secondDerivative": "0",
                "scaleDownMarginOfGradient": "1.0",
                "scaleDownMarginOfSecondDerivative": "0.2"
            },
            "memoryConsumption":
            {
                "average": "6000",
                "gradient": "0",
                "secondDerivative": "0",
                "scaleDownMarginOfGradient": "1.0",
                "scaleDownMarginOfSecondDerivative": "0.2"
            },
            "loadAverage":
            {
                /* Load average is multiplied by 100 then divided by no. cores.
                 * Thus it's basically box utilisation % */
                "average": "40",
                "gradient": "0",
                "secondDerivative": "0",
                "scaleDownMarginOfGradient": "1.0",
                "scaleDownMarginOfSecondDerivative": "0.2"
            }
        }
}

Hi Manas,

Can you please share the autoscaling policy JSON which you have used for 
subscribe cartridges.

Thanks !

Hi,

I am getting following  messages periodically in wso2carbon.log for all of the 
subscribed cartridges which came Active.
Want to know what is triggering this error to come & what is its impact if any.
