You can use the power of the alerting features with Watcher to get alerts on error occurrences. The Watcher assistant, which is available on the Errors overview page, can help you set up a watch per service.
Configure the watch with occurrences threshold and time interval and set the desired actions, such as email or Slack notifications. Your team can be set up with alerts in minutes.
Watches are managed separately in the dedicated Watcher UI available in Advanced Settings.
