In APM Insight, you can configure alerts at the application level. You can choose to receive alerts if there's a threshold breach in any of the following parameters: application response time, error count, error rate, and exception count. You can choose one or all four parameters while configuring your alerts.
You also don't need to configure alerts with the same specifications for every APM Insight application. Instead, save yourself the time and use existing APM alert templates if you'd like to use the same existing configurations for your new APM applications.
