Synology

Process webhook notifications from Synology DSM with automatic device identification, severity detection, and priority inference.

Input Handling

For string and binary inputs, the interpreter returns a simple notification with title Synology DSM, priority 3, and the tag synology. The full parsing pipeline only runs for JSON object inputs.

Payload Detection

When the input is a JSON object, the interpreter tries multiple field names to accommodate Synology's variable payload format:

• Message body: Checks text, message, body, content, description (in order).
• Hostname: Checks prefix field (format: hostname | date time), then hostname, host, device.
• Timestamp: Extracted from prefix or from date/time fields.
• Severity: Checks severity and level fields.
• Event type: Checks event, category, type fields.

Priority Inference

Priority is determined in two ways:

1. Explicit severity field — critical = 5, error = 4, warning = 3, info = 2.
2. Keyword matching (if no severity field) — Scans the message body for keywords:
   • "is down", "lost link", "unreachable" = 5 (urgent)
   • "error", "bad sector", "failure" = 4 (high)
   • "warning", "packet loss", "high latency", "running out" = 3 (default)
   • "is available", "restored", "completed successfully" = 2 (low)

Notification Output

• Title: The hostname if available, otherwise Synology DSM.
• Body: Timestamp (bold) and message text.
• Priority: Inferred from severity or keywords.
• Tags: Includes synology, sanitized event slug (if present), severity (if explicitly set and not info), and emoji.
• Actions: Link to the DSM URL if provided in ntfy-reverse-proxy.url field.

Custom Fields

Add an ntfy-reverse-proxy object to the payload with a url field pointing to your DSM login page. This creates an "Open DSM" action button in the notification that also clears it when tapped.
