Alerts

CPU, memory, and downtime alert rules with email, Slack, and webhook channels.

The project’s Alerts tab defines rules evaluated continuously in the background. When a rule fires, Dequel notifies the channel you chose — and failure emails link straight back to the logs.

Rule types

• CPU — fires when average CPU % exceeds your threshold (default 80%) for the window.
• Memory — same for memory % (default 85%).
• Downtime — fires immediately when the deployment stops responding.

Create a rule with a metric, threshold (1–100), and channel. Toggle rules on/off without deleting them.

Channels

• Email — delivered through your SMTP settings. Failure notifications include a link to the relevant logs.
• Slack — posts to an incoming webhook URL (Slack webhook format).
• Webhook — generic HTTPS POST to any URL for PagerDuty, Opsgenie, or custom receivers.

Evaluation cadence

Rules evaluate on the platform interval (ALERT_EVAL_INTERVAL_MS, default 60s; see System Configuration). Thresholds combine with duration so brief spikes do not page you.
