Alert channels

Lenses supports secure channels configuration to allow fine-tuned alerts routing. You can choose from predefined channel types like Slack, PagerDuty, DataDog, Alert Manager, CloudWatch, or use custom Webhook to connect to any external service of your choice.

Once the channel is created, it can be used by you or any other user with correct permissions to route alerts of your choice into this specific channel. It means you can send a Slack notification when Kafka broker is down, or send notifications to PagerDuty when some partitions are offline. It’s up to you now where specific alerts will be delivered.
