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"
}
}
}
Regards
Manas

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.
