Overview

This node performs a Heapsnapshot operation within the Observability resource. It is designed to capture and analyze memory heap snapshots, which is useful for monitoring and debugging memory usage in applications. Common scenarios include identifying memory leaks, optimizing memory consumption, and understanding application performance.

Use Case Examples

1. Capturing a heap snapshot to analyze memory usage during a specific workflow execution.
2. Using heap snapshots to detect and troubleshoot memory leaks in a Node.js application integrated with n8n.

Properties

Output

JSON

• heapSnapshotData - The captured heap snapshot data representing memory usage at the time of the snapshot.
• status - Status of the heapsnapshot operation, indicating success or failure.
• timestamp - The time when the heap snapshot was taken.

Dependencies

• Requires an API key credential or authentication token to access the observability service endpoint.

Troubleshooting

• If the node fails due to SSL certificate issues, enable 'Ignore SSL Issues' to bypass validation, but be aware of security risks.
• Timeout errors may occur if the server is slow to respond; increase the 'Timeout' value accordingly.
• Proxy configuration errors can prevent the node from connecting; verify proxy URL and credentials if used.
