Alert rules

Alert rules fire a webhook when a metric crosses a threshold for a given duration.

Add an alert rule

curl -X POST https://manage.yourdomain.com/api/alerts/rules \
  -H "Authorization: Bearer sd_..." \
  -H "Content-Type: application/json" \
  -d '{"app_id":1,"metric":"cpu_pct","operator":">","threshold":80,"duration_sec":300,"webhook_id":1,"enabled":true}'

Field	Type	Notes
`app_id`	int	Target app (omit / null for system-wide)
`metric`	string	`cpu_pct`, `mem_bytes`, `mem_pct`
`operator`	string	`>`, `<`, `>=`, `<=`
`threshold`	float	Numeric threshold
`duration_sec`	int	Sustained breach window before firing
`webhook_id`	int	Webhook to dispatch to
`enabled`	bool	Toggle without deleting

Compose label shortcuts

Default rules can be created automatically from compose labels:

labels:
  simpledeploy.alerts.cpu: ">80,5m"
  simpledeploy.alerts.memory: ">90,5m"

Format: {operator}{threshold},{duration}. Rules created this way can be tuned or disabled later via the API/UI.
