Consume Aruba Central Next Gen API

Overview

This node interacts with the Aruba Central Next Gen API to retrieve information about Access Points (APs) that have performance issues within a specified site. It is designed for network administrators and IT professionals who want to monitor wireless infrastructure health by identifying APs experiencing problems such as high channel utilization, poor channel quality, elevated error rates, or high CPU usage.

Typical use cases include:

  • Proactively detecting APs that may degrade wireless network performance.
  • Automating alerts or remediation workflows when APs exceed defined performance thresholds.
  • Generating reports on AP health status for network maintenance and troubleshooting.

For example, a user can configure this node to fetch all APs in a particular site that have channel utilization above 80% or CPU utilization above 80%, helping pinpoint devices that might require attention.

Properties

Name Meaning
Debug Mode Enable detailed debug logs for troubleshooting purposes.
Domain Select the API domain to interact with:
- Monitoring: Monitor devices, clients, and sites
- Configuration: Configure devices, groups, and profiles
Site ID The identifier of the site for which to retrieve AP information.
Issue Detection Options Collection of threshold settings to detect AP issues:
- High Channel Utilization Threshold (%) (default 80%)
- Low Channel Quality Threshold (%) (default 50%)
- High Error Rate Threshold (%) (default 5%)
- High CPU Utilization Threshold (%) (default 80%)

Output

The node outputs JSON data representing a list of Access Points that meet the specified performance issue criteria. Each item typically includes details about the AP's identity and its performance metrics relative to the configured thresholds.

If binary data were involved (e.g., logs or diagnostic files), it would be summarized accordingly; however, this node focuses on JSON output describing AP performance states.

Dependencies

  • Requires an active connection to Aruba Central Next Gen API via an API authentication token credential.
  • The node depends on n8n's OAuth2 credential setup for Aruba Central Next Gen.
  • No additional external dependencies are indicated beyond the bundled helper modules for operation execution and logging.

Troubleshooting

  • Common Issues:

    • Incorrect or missing Site ID will result in failure to retrieve AP data.
    • Misconfigured thresholds may lead to no APs being returned if none meet the criteria.
    • Network connectivity or API authentication failures can cause errors.
  • Error Messages:

    • "Unknown error in node execution": Generic catch-all error; check API credentials and network access.
    • Errors related to invalid parameters usually indicate missing required fields like Site ID or invalid threshold values.
  • Resolution Tips:

    • Verify that the Site ID corresponds to an existing site in Aruba Central.
    • Ensure API credentials are valid and have sufficient permissions.
    • Enable Debug Mode to get detailed logs for diagnosing issues.
