Proactive Meraki Network Health Monitor
detail.loadingPreview
This n8n workflow automates the crucial task of monitoring your Cisco Meraki network infrastructure. It proactively identifies sites experiencing high latency or significant packet loss, enabling rapid response and maintaining optimal network performance.
About This Workflow
This comprehensive n8n workflow empowers IT professionals and network administrators to automatically monitor the health and performance of their Cisco Meraki networks. By leveraging the Meraki API, the workflow systematically retrieves organization and network details, then fetches critical performance metrics like packet loss and latency. It then applies custom logic to calculate average performance over recent intervals and intelligently filters out only those sites that exceed predefined thresholds for latency (300ms) or packet loss (2%). This provides a powerful, automated mechanism to detect and flag potential network issues before they impact end-users, ensuring proactive network management.
Key Features
- Automated Meraki API Integration: Seamlessly connect to your Cisco Meraki dashboard to fetch organization, network, and performance data.
- Dynamic Network Data Retrieval: Automatically iterates through all your Meraki organizations and networks to gather comprehensive information.
- Real-time Performance Monitoring: Extracts and processes time-series data for packet loss and latency across your networks.
- Customizable Performance Thresholds: Define specific limits (e.g., >300ms latency, >2% packet loss) to identify problematic sites.
- Intelligent Issue Filtering: Automatically filters and highlights only the networks that are currently experiencing performance degradation.
How To Use
- Manual Trigger: Initiate the workflow by clicking "Execute Workflow". For automated monitoring, consider replacing this with a
Schedule Trigger. - Get Meraki Organizations: Ensure your Meraki API key is configured as an
HTTP Header Authcredential (e.g., "Header Auth account" with ID "12"). Set theAcceptheader toapplication/json. - Get Network IDs: This node dynamically retrieves network IDs for each organization. Confirm your Meraki API key is correctly passed in the
Authorizationheader. - Critical Missing Step - Fetch Device Performance Data: Crucially, a node to fetch device loss and latency data (e.g., another HTTP Request node targeting a Meraki performance API endpoint) is implied but not present in this snippet. You will need to add a node here that pulls time-series performance data for each network or device, which should output fields like
networkIdand atimeSeriesarray containinglossPercentandlatencyMs. - Average Latency & Loss over 5m / Filters Problematic sites: These
Codenodes contain JavaScript logic. Review and adjust the hardcoded thresholds (currently 300ms latency and 2% loss) if you need different criteria for identifying problematic sites.
