Aria Automation UI performance degrades when managing over 150 Image Mappings per profile

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

When managing Azure image mappings within Aria Automation 8.18.x, customers may experience significant UI unresponsiveness and slow loading times if an image profile contains more than the maximum supported number of images. For instance, profiles with over 300 image mappings have been observed to take 10-15 minutes to load in the UI, rendering management through the graphical interface impractical. This issue specifically affects the management of image profiles that utilize the imageRef property for Azure image mapping.

Environment

VMware Aria Automation 8.x

Cause

The root cause of the UI performance degradation is exceeding the documented maximum supported number of images per image profile. According to the official Aria Automation reference architecture, a single image profile supports a maximum of 150 images. When this limit is surpassed, the UI struggles to process and display the large number of entries, leading to severe slowdowns and unresponsiveness.

Resolution

To resolve the UI performance degradation, it is recommended to reduce the number of image mappings per image profile to stay within the documented limit of 150 images. If an image profile currently exceeds this limit:

1. Reduce Image Mappings: Consolidate or split image mappings across multiple image profiles to ensure no single profile contains more than 150 images.
2. Workaround (API Management): If immediate UI management is required for an oversized profile, or if splitting profiles is not immediately feasible, management of the image profile's logical construct can still be performed using API calls (e.g., via curl or Postman). While tedious, this method bypasses the UI performance bottleneck.
