Dead Man's Snitch will send alerts to Opsgenie when a Snitch goes missing or errors. Pausing a Snitch will automatically acknowledge alerts. Alerts will be closed when a Snitch starts reporting successfully again.
To integrate with Opsgenie you'll need to create an API Integration with appropriate permissions then create a new integration in Dead Man's Snitch.
Create a new API Integration in Opsgenie with the below permissions. The steps are different depending on which plan your team is on so follow the steps here.
