How to adjust maxIssuesThreshold for SDDC Manager LCM precheck results rendering

Products

• VMware SDDC Manager / VCF Installer
• VMware Cloud Foundation

Issue/Introduction

When you prepare for SDDC Manager upgrades, a "Precheck"  can be run to find potential issues (errors or warnings) that might affect the upgrade.

For large VCF environments, this Precheck can generate a huge amount of data in excess of 100 MB.
Attempting to view all these results directly in the SDDC Manager interface (under Workload Domains > Domain > Upgrades > Prechecks > View Details), might take a very long time to load or even freeze completely due to the large amount of information.

The system has a built-in limit (maxIssuesThreshold). It will only display the Precheck results directly in your browser if the number of issues found is below this limit.
If there are too many issues to display directly

Alternatively, the EXPORT FULL REPORT option to view in CSV format and opened in Microsoft Excel or Google Sheets.

Environment

VCF 9.1.x
