When in Australia we had  DST change Sunday, 5 April 2020 (at 3:00:00 am clocks were turned backward 1 hour to  2:00:00 am )we’ve got a few false alarms that applications were not running.

The alerts are set to trigger if there is no any events within the last 15 minutes. The application sends heart beat messages every 5 minutes.

Unfortunately, SumoLogic shows that between 2am and 3am there were no events.

Can you suggest any way to prevent these false alarms?

  Never mind, it’s a bug in our applications when we generate heartbeat events during DST change
