Mitel Performance Analytics.
Would like the ability to filter alerts so that an alert has to be present for a certain amount of time before sending the email.

Example, we have the occasional SIP link alarm that only lasts for 5 seconds. But we get sent the alert. We send alerts to Pagerduty to alert on call team members out of hours. We don't want to be called during the night for an issue that cleared after 5 seconds.

So would be nice to have a filter option that we could set to only send an email if an alarm was present for more that 180 secs for example.
