Products

• VMware Aria Suite

Issue/Introduction

• This article describes a scenario where Capacity data for Cluster Compute Resources became unavailable in Aria Operations SaaS / Operations On-Prem

Environment

• Aria Operations (SaaS)
• Aria Operations 8.x

Cause

• An incorrect custom alert definition with duplicate symptom sets prevented the Resource cache from loading
• This, in turn, hindered data collection for the Capacity engine and Super Metrics for specific resources

Resolution

• Access the Custom Alert Definitions: Navigate to the section where custom alerts are configured within Aria Ops SaaS / Operations On-Prem (Configure > Alerts > Alert Definitions)
• Identify Relevant Alert Definition: Locate the customized alert definition associated with Cluster Compute Resources (E.g., "Company_name - Cluster CPU Capacity Remaining is low")
• Review Symptom Sets: Verify if the same symptom set is used multiple times within the alert definition (An E.g. screenshot of Duplicate Symptom Sets is geiven below)
• Remove Duplicate Symptom Sets: If duplicates are found, delete the unnecessary ones
• Wait for Data Refresh: Allow some time (30 minutes) for the Resource cache to reload and data collection to resume

Additional Information

• Incorrect custom alert definitions can impact data collection for various resources within Aria Ops SaaS / Aria Operations On-Prem
• Ensure proper management and avoidance of duplicate symptom sets in custom alert definitions
• This specific issue might not be exclusive to the mentioned Aria Ops SaaS / Aria Operations On-Prem version and could potentially occur in other versions as well
