About This Workflow
Overview
This n8n workflow is designed to automate the monitoring and logging of server health data. It utilizes a Webhook Trigger to receive real-time server status updates. The incoming data is then processed by Text Splitter, Embeddings, and Weaviate nodes to create a searchable vector database. A RAG Agent with a Chat Model and Window Memory then intelligently processes this data. Finally, the processed information is appended to a Google Sheet using the Append Sheet node, and any errors encountered during the process trigger a Slack Alert.
Key Features
- Real-time server health data ingestion via Webhook.
- Advanced data processing using Langchain (Text Splitter, Embeddings, RAG Agent).
- Intelligent data storage and retrieval with Weaviate vector database.
- Automated logging to Google Sheets for historical tracking.
- Error alerting to Slack for immediate issue notification.
