Powershell Output to an Email message

Try these 2 alert variables.

Component Statistic: ${N=SwisEntity;M=ComponentAlert.StatisticData}

Component Message: ${N=SwisEntity;M=ComponentAlert.ComponentMessage}

On the Alert email action, within the body of the message this would be the variable you would use:

Integer:

${N=SwisEntity;M=MultipleStatisticData.NumericData}

Char:

${N=SwisEntity;M=MultipleStatisticData.StringData}

You can find these on the variable list within the alert actions tab.

Depending on your powershell output you can use either.
