Red Hat recommends running the Log Collection Analysis tool prior to performing updates and for troubleshooting. The tool analyses your environment and displays any known issues that may prevent you from performing an update and suggests how to resolve the issue.

The tool gathers detailed information about your system and presents it as an HTML file.

Note

The Log Collection Analysis tool is available from Red Hat Virtualization 4.2.5.

Procedure

  1. Install the Log Collection Analysis tool on the Manager: 

    # yum install rhv-log-collector-analyzer

  2. Run the tool: 

    # rhv-log-collector-analyzer --live
    Copy to Clipboard Toggle word wrap

    A detailed report is displayed.
