-|`MetricTriggerMetricResourceUri`| Specifies the resource that the `MetricTriggerMetricName` metric belongs to. `MetricTriggerMetricResourceUri` can be any resource and not just the resource that's being scaled. For example, you can scale your VMSS based on metrics created by a load balancer, database, or the VMSS itself. The `MetricTriggerMetricName` must exist for the specified `MetricTriggerMetricResourceUri`.

 |`MetricTriggerTimeGrain`|The sampling frequency of the metric that the rule monitors. `MetricTriggerTimeGrain` must be one of the predefined values for the specified metric and must be between 12 hours and 1 minute. For example, `MetricTriggerTimeGrain` = *PT1M*"* means that the metrics are sampled every 1 minute and aggregated using the aggregation method specified in `MetricTriggerStatistic`.
 |`MetricTriggerTimeAggregation` | The aggregation method within the timeGrain period. For example, statistic = "Average" and timeGrain = "PT1M" means that the metrics are aggregated every 1 minute by taking the average.

 |`MetricTriggerDividePerInstance`| When set to `true` divides the trigger metric by the total number of instances. For example, If message count is 300 and there are 5 instances running, the calculated metric value is 60 messages per instance. This property isn't applicable for all metrics.
 | `ScaleActionDirection`| Specify scaling in or out. Valid values are `Increase` and `Decrease`.

 |`ScaleActionCooldown`| The minimum amount of time to wait between scale operations. This is to allow the metrics to stabilize and avoids [flapping](./autoscale-flapping.md). For example, if `ScaleActionCooldown` is 10 minutes and a scale operation just occurred, Autoscale won't attempt to scale again for 10 minutes.
