Notification Channels

Notification Channels are destinations for Last9 to send alert notifications. We support the following channel types: Slack, PagerDuty, Opsgenie, Webhook, and Email. The Webhook channel supports auto-detection for MS Teams, Flock, Google Chat, Telegram, Jira, and Zenduty.

Open the Channels section from the Alerting sidebar to see every configured channel, its Usage (the alert groups and scheduled searches using it), and whether Send Resolved is enabled. Use Add Channel to create one and Settings for channel defaults.
