Monitor a file for changes and send an alert

This automation can monitor any text-based files including logs, CSVs, JSON, configuration files, and documents. The system compares file contents rather than just modification timestamps, detecting actual content changes even if the file size remains the same.

Common use cases include monitoring server logs, configuration changes, or shared documents where version tracking is critical. For binary files, you would monitor checksums rather than direct content comparisons.

• Works with any text encoding format
• Handles large files efficiently
• Configurable change sensitivity

Alerts are delivered in real-time, typically within seconds of a detected change. The workflow polls files at configurable intervals (as frequently as every minute) and immediately triggers notifications through SIGNL4's multi-channel alert system.

For mission-critical files, you can set up immediate SMS or voice call alerts to ensure rapid response. The system includes prioritization rules so urgent changes bypass any notification queues.

Yes, SIGNL4 supports team alerting where notifications are broadcast to all authorized personnel. You can configure different notification channels per team member (SMS for some, push notifications for others) based on their roles and response requirements.

The system also tracks acknowledgment of alerts to ensure critical changes aren't missed. Escalation rules can be set up to notify additional team members if initial recipients don't respond within a specified time.

• Role-based alert routing
• Response tracking and escalation
• Customizable alert schedules

The workflow includes built-in error handling and retry logic. If the monitoring service is temporarily unavailable, it will resume checking files once connectivity is restored. Missed changes can be detected when the system comes back online.

For critical systems, you can configure secondary alert paths or heartbeat monitoring to detect any interruptions in the monitoring service itself. The n8n platform provides health monitoring features to ensure reliability.

The workflow operates with read-only access to monitored files and doesn't store file contents permanently. All alert transmissions are encrypted, and SIGNL4 provides enterprise-grade security for notifications.

For sensitive files, you can implement additional encryption at the file system level before monitoring. Access controls ensure only authorized systems can read monitored files, and alert messages can be configured to show only necessary details.

• End-to-end encryption options
• Compliance with data protection standards
• Audit logging of all access

Yes, with additional configuration. While this template monitors local or network files, n8n can integrate with cloud storage APIs to monitor files on platforms like Google Drive, Dropbox, or SharePoint.

The workflow would periodically check file versions or content hashes rather than direct file access. Cloud monitoring typically requires API authentication and may have different rate limits than local file system monitoring.
