Dell EMC Unity
Overview
The Dell EMC Unity integration with Motadata AIOps enables the extraction and monitoring of comprehensive health, performance, and capacity KPIs across storage arrays, enclosures, file systems, and logical unit numbers (LUNs). These KPIs are essential for operations teams to monitor infrastructure health, perform capacity planning, and trigger anomaly detection or alerts.
This documentation outlines all supported KPIs, grouped by category and displayed in a structured tabular format with metric names and descriptions.
Prerequisites
Please ensure the below prerequisites:
- The Dell EMC Unity device must be accessible over the network.
- API or SNMP access must be enabled and credentials should be available.
- Appropriate roles/permissions are required to fetch monitoring data.
- The device must be discovered successfully via the AIOps Discovery Module.
