  • Troubleshooting:

    • Utilize vCenter logs/monitoring for VM/host issues.
    • Identify/resolve performance bottlenecks.
    • Employ effective troubleshooting tactics.
    • Interpret error messages, alerts, and logs.

  • Monitoring and Reporting:

    • Use vCenter tools for performance monitoring.
    • Generate reports from performance data.
    • Analyze data from logs.
    • Analyze CPU, memory, and storage utilization.

  • Performance Tuning:

    • Address performance issues for VMs/hosts.
    • Optimize settings for optimal VM performance.
    • Fine-tune resource parameters.
    • Diagnose performance issues to find root causes.
